Synth modules

Notes: 'Beast's Chalkboard' is dual channel stepped voltage source and adder for your eurorack modular synthesizer system. It primarily is intended as a dual octave switcher for VCO's but has many other uses including sequence transposition, FM ratio creation, buffered CV distribution and VCO calibration.

Technical Specifications:

Supply: +/-12V (Reverse voltage & polyfuse protection)
Current Draw: ~30ma
Size: 6 HP
Depth: 22mm (including power header)
Offset Error: +/- 10mV

Notes: This is a simple 1U module designed to allow the monitoring of a system using headphones. However, if your cat isn't easily scared, the headphone jack doubles as a TRS stereo line level output. Simply connect the signal that you want to monitor to the 1/8? jacks, plug in your headphones, and adjust the volume as desired.

Notes: The Listen IO is a simple module which gets signals in and out of a Eurorack system by converting to and from normal modular levels. The top section converts any external signal to modular levels by providing up to 30x gain (+30dB), allowing you to use table-top synthesizers, keyboards, phones/tablets, computers, toys, microphones, etc. in your patches. The bottom section does the opposite: modular signals are converted to normal line level signals. The bottom two jacks can be used as line outs or as headphone jacks, so you and a friend can listen in stereo at the same time.

Each section has two inputs and outputs for use with a stereo signal or two mono signals. An LED bar graph for each output shows the signal level and clipping.

Notes: An expander for Zadar, adding one more assignable input for each Zadar channel and manual triggers.

Notes: Excellent Eurorack sequencer based on random chance and evolving patterns. Dial in a series of notes and build melodies, generate and tweak patterns in real time. Huge depth for studio production or live performance.

Supplier's Notes:
The Melodicer from Vermona is a CV/Gate sequencer with an innovative concept; the melody sequencer offers twelve faders for setting the note probability and two dice-(or random) buttons for generating melody and rhythmic structure.

Notes: Module A-185-2 is a precision control voltage adder/buffer. Precision means that the amplification of the inputs without attenuators is exactly 1.00 and is suitable to add control voltages for the pitch control of VCOs (e.g. from keyboard + sequencer 1 + sequencer 2). Summing resistors matched to 0.1% are used to obtain an accuracy of 0.1% for the added voltages.

The module is equipped with four CV inputs: one with attenuator and three without attenuator. Each input is normalled to +1 V (i.e. if no plug is inserted the input contributes 1 V to the sum appearing at the output).

The input with attenuator can be used for common modulations (e.g. from an LFO, ADSR, Theremin, Pitch-Bender) for all VCOs connected to the output. The Lev.1 control is used to adjust the depth of the modulation, the first switch selects the polarity of the modulation. If no signal is connected to the first socket the attenuator works as a (fine) tuning knob because a voltage in the range 0...+1V (right position of the switch) or 0...-1V (left position of the switch) is added to the CV output.

The inputs without attenuators are planned to add control voltages coming out of keyboards, sequencers, Midi-to-CV interfaces, ribbon controllers or other CV sources that follow the 1V/oct standard. For example the CV of a keyboard can be used to transpose the CV coming from a sequencer, or the CV of a slow sequencer can be used to transpose the CV from a fast sequencer.

Each input is equipped with a three-position switch that determines if the corresponding voltage is added (right position), subtracted (left position) or if the input has no effect (centre position). If no plug is inserted the corresponding switch works as an octave switch for the lower three sections as the default 1 V are added or subtracted to the output voltage according to the switch position. The first switch can be used to add a variable voltage to the sum output. The variable voltage is adjusted with the Lev.1 control and the knob works then as kind of a (fine) tuning control.

The module is equipped with 4 outputs: three non-inverting and one inverting ouput. An internal jumper can be used to connect the non-inverted or inverted output to the CV line of the A-100 bus. That way the module can used to control several VCOs that are connected to the same bus board as the A-185-2 (same functionality as A-185-1).

Notes: Multi-model stereo delay with reverb, featuring tape, bucket brigade and crossfading digital models, plus saturation, filters, internal modulation plus tons of CV control. Vibey as hell.

Supplier's Notes:
It's all gone a bit wobbly

Intellijel's design goal for Sealegs was to create the warmest, most musical and organic delay module possible - something that would sweeten and enhance any audio one chose to feed into it. As such, great care has gone into modelling the most distinctive and desirable sonic characteristics of three different types of delay circuits: Tape; Bucket Brigade, and Crossfading Digital.

A plethora of onboard controls enable you to dial in exactly the sound you want; synced or un-synced delays times (for both left and right channels); a built-in modulator with seven morphing waveshapes, a Wow & Flutter emulation, and an envelope follower; plus dedicated low- and high-pass filters; built-in hiss & crackle noises; per-model colour controls; a spacious reverb; and a re-configurable signal flow through the unit. In addition, attenuverted modulation inputs abound - ensuring the delay ebbs and flows with your musical needs.

Features
Three Unique delay models with per-model "Color", modulation behaviour, and saturation/limiting
Three Stereo configurations (PONG, L/R, Time/Width)
Built-in modulator with multiple, morphing wave shapes
Lush, routable 1970s-inspired reverb
Noise control to introduce hiss and crackle.
Highpass and lowpass filters for filtered repeats
Input drive with level trim
Per-model Freeze functionality for holding the delay contents and looping
Delay times up to 6 sec (L channel) and 8 sec (R channel, Width adds 33% to Time)
9 CV inputs (with attenuverters)
Stable external clock syncing (or tap tempo)
96 kHz, 32-bit stereo floating point processing

Size: 20HP
Depth: 29mm
Power: 116mA @ +12V 10mA @ -12V

Notes: Mult is a 2 input, 6 output signal splitter. Channel 1 is normalled to channel 2 when no cable is present, allowing the user to split an input signal six ways, or two input signals with three outputs each.

Notes: Module A-148 (Dual S&H) has two identical sample & hold modules, designed to produce 'staircase' voltages. The signal present at the sample input is sampled at a rate set by the signal at the trigger input, and held at that voltage at the S&H output.

The exact shape of the staircase depends on the sort of waveform at the sample input: NOISE or RANDOM signals produce random patterns; an LFO produces rising or falling staircase patterns.

Two LEDs for each S&H indicate the voltage (positive or negative) of the sampled signal.

Notes: Module A-118-2 is the slim version of module A-118-1 and offers essentially the same features as the A-118-1. But the distances between the controls are smaller and rubberized small-sized knobs are used. In return the front panel has 4 HP only which is half the width of the A-118-1. The module is primarily planned for applications where only limited space is available. The functional difference between A-118-1 and A-118-2 is the additional T&H/S&H unit which is not included in the A-118-1.

The module generates the signals white noise, colored noise, continuous random voltage and stepped random voltage (derived from the continuous random voltage by means of a S&H/T&H unit).

The noise signal is generated 100% analog by amplification of the noise of a transistor. White and colored noise are usually used as audio sources. The random voltages are normally used as control voltages (e.g. for filter frequency or any other voltage controlled parameter).
The A-118-2 gives you the ability to mix the relative amounts of Red (low frequency component) and Blue noise (high frequency component) in the colored noise output.

For the continuous random voltage the rate of change (Rate) and amplitude (Level) of the random voltage can be adjusted. The continuous random voltage is derived from the colored noise signal by low pass filtering. Consequently the settings of the controls for the colored noise (Blue, Red) affect the behavior of the random voltage! A dual color LED (red = positive / yellow = negative output voltage) indicates the continuous random voltage.

The continuous random voltage is used as source for the S&H/T&H unit. The type of operation can be set to S&H (sample and hold) or T&H (track and hold). When T&H is chosen the output signal follows the input signal (= continuous random voltage) as long as the Clock input is "high". As soon as the clock signal changes to "low" the last voltage is stored. When S&H is chosen the input signal (= continuous random voltage) is sampled at the rising edge of the Clock signal.

For the Clock signal a "digital" signal (e.g. Clock, Gate, rectangle output of an LFO) is required. It does not work with slowly changing continuous CV signals. Another dual color LED (red = positive / yellow = negative output voltage) indicates the stepped random voltage.

Controls:

Blue: share of the high frequencies in the the colored noise output
Red: share of the low frequencies in the the colored noise output
Rate: rate of change of the continuous random voltage
Level: amplitude of the continuous random voltage
TH/SH: switches between T&H and S&H

Inputs and outputs:

RND: continuous random voltage output (with LED display)
TH/SH: stepped random voltage output (with LED display)
Clk: Clock input of the S&H/T&H unit
C Noise: colored noise output
W Noise: white noise output

Important notes:

After power on it takes a few minutes until the two noise signals and the random signals are generated. The module is not faulty when after power on the signals do not appear immediately!

The S&H/T&H function is realized by pure analog circuitry (electronic switch followed by a holding capacitor and buffer). Consequently the output voltage drifts a bit in the holding state because the capacitor is discharged by parasitic resistors. The drift depends also upon environmental conditions like humidity or temperature.

Notes: The Spectral Multiband Resonator from 4ms Company is an innovative resonant filter which can process audio like a classic filter bank, ring like a marimba when plucked/struck, vocode, re-mix tracks, harmonize, output spectral data, quantize audio to scales, and much more...
A gorgeous ring of colored lights displays the frequency of each filter, as well as the levels and current scale selection(s).

At a glance, the SMR works like a normal six-band graphic EQ: six frequency band-pass filters are mixed together using sliders. Resonance/Q is variable, which changes the "ringy-ness" or width of the bands.

But here's where comparison stops. The frequency of each channel is treated like a note in a scale, and the six bands form a chord. Spin the Rotate knob and the "notes" circle around the scale, rotating back to the bottom once they've reached the top. Adjust Spread and the distance (interval) between each note changes. Triggers for up/down motion, CV inputs for sequencing and scale selection allow for flexible control with external modules. Morph, which automatically cross-fades between frequencies, together with variable Slew allows rhythmic clocks drive the SMR as a variable-speed evolving resonant filter.

At maximum Resonance/Q, the SMR can be struck like a gong or marimba by inputting clocks or triggers. The frequency of each channel is quantized to a scale: beautiful chords, ethereal tones and eerie ambiance flows easily. With lower resonance, the SMR can pull out particular frequency bands, and sweep these across the spectrum.

Two 1V/octave Frequency jacks allow for tracking even and/or odd bands and creating floating melodies over evolving chord bases, or complex percussive membrane sounds.

Save your settings into one of six storage banks, and recall on the fly. On startup, the SMR instantly jumps to the last saved settings. The color scheme of the lights can be adjusted, so if you prefer all white lights on your modular, you can have that (or all red, or rainbows, pastels, etc..)!

Advanced features:
- Program your own scale. The frequency of each of the 20 notes can be assigned by setting the octave, the semi-tone, and coarse and fine micro-tone. Up to 11 scales can be saved permanently in the user bank
- Adjust color scheme of the LEDs. Pick a pre-programmed color scheme or create your own using the sliders to set Red/Green/Blue values. Custom color schemes can be saved permanently
- Save your settings in one of six parameter banks. Note position, scale and bank selection, Q value, Lock settings and color scheme can be saved and recalled on the fly. On startup, the SMR loads settings from the last saved bank.
- Optional alternative filter type for a more exponential decay when plucked and different timbral qualities. Freq jacks no longer track 1V/oct in this mode.
- Slider LEDs can be assigned to display level for each channel (combination of slider position and CV on the jack), or clipping for each channel.

Notes: Small and efficient MIDI to CV courtesy of Intellijel's 1U series. Works in conjunction with an Intellijel case or the MIDI IN Jacks 1U module to give you Pitch, Velocity, Mod, CC, Gate, Trig, Clock and Reset.

Supplier's Notes:
The MIDI 1U system provides all the essentials to control and sync your Eurorack modular from your computer, mobile, or hardware MIDI device with a minimum of fuss. Several of the module's most important features can be changed using the two front panel buttons, with full configuration capabilities offered via the Intellijel Config app, which is available for both Mac and Windows. The connectivity, feature set, expandability, and compact size make the MIDI 1U system ideal for integrating your modular gear with the rest of your rig.

Intellijel's MIDI 1U system comprises several elements, which work together to provide flexible, programmable MIDI-to-CV conversion to your Eurorack modules: The system comprises two mandatory components, and one optional component:

MIDI 1U module - This 14HP 1U module receives MIDI from an attached, external MIDI input connector (7U case, Palette case, or MIDI IN Jacks 1U module), and extracts (by default) Pitch, Velocity, Mod, CC, Gate, Trig, Clock and Reset messages i sending the proportional voltages to individual 3.5mm jacks for patching.If desired, the CC and MOD jacks may be configured to respond to either Channel Aftertouch or High Resolution CC, and the Reset jacks can be configured as a Run jack, instead. Additionally, MIDI 1U features an alternate Dual Mode, which maintains the Clock & Reset functionality, but uses the other six jacks to transmit Pitch, Velocity and Gate messages derived from two separate MIDI channels.
MIDI input connector - the MIDI 1U module does not have its own MIDI input jack. This enables you to use the MIDI/USB inputs built-in to your Intellijel 7U Performance Case or Palette Case. If you don't own one of these cases, you can purchase the MIDI IN Jacks 1U module to connect an external MIDI device.
MIDI Expander 1U module - This optional 14HP 1U module connects to the MIDI 1U module and adds an additional eight 3.5mm CV outputs. These outputs are fully programmable using the Intellijel Config app, and greatly expand MIDI 1U's ability to control your entire Eurorack system.

Notes: Module A-130-8 contains eight linear voltage controlled amplifiers (VCAs). Each VCA features a control voltage input (CV), a signal input (In) and a signal output (Out). In addition three mixers are included: the socket labelled "1-4" outputs the sum of the VCAs 1-4, the socket labelled "5-8" outputs the sum of the VCAs 5-8, the socket labelled "1-8" outputs the sum of all eight VCAs.

The signal inputs are able to process levels up to about 20Vpp without clipping (20Vpp = 20V peak-to-peak or about -10V...+10V) . Each CV input is equipped with a trimming potentiometer that is used to adjust the sensitivity of the CV input in question. In the factory the module is adjusted for the CV range 0...+5V but can be re-adjusted by the user for other control voltage ranges (e.g. 0...+10V).

The amplification range for each single VCA is 0...1. The signals of the sum outputs have a lower amplification to avoid distortion at the sum outputs.

The VCAs and mixers are fully DC coupled, i.e. the module can be used for the processing of both audio and control voltage signals. The control voltage and signal inputs can be normalled by means of small solder pads (e.g. 1 > 2 > 3 > 4 and so on, or 1 > 5, 2 > 6, 3 > 7, 4 > 8 for the stereo application mentioned below).

Typical applications

any kind of VCA application (e.g. voltage controlled attenuation of audio or control voltage signals)
two voltage controlled mixers with four channels each
voltage controlled stereo mixer with four channels each, for this the control voltage inputs have to be correspondingly patched or internally normalled: CV1=CV5 /CV 2=CV6 / CV3=CV7 / CV4=CV8
voltage controlled mixer with eight channels
add-on for the Joystick module A-174-4
Technical notes

The following document shows the positions and functions of the jumpers and trimming potentiometers of the module: A130_8_trimming_potentiometers_and_jumpers.pdf
When the trimming potentiometer in question is moved CCW (counterclockwise) the sensitivity of the CV input in question increases (view to the top edge of the module).
Trimming procedure: apply the max. CV voltage that will occur in your application (e.g. +8V) to the CV input and a constant audio signal to the audio input (e.g. a VCO sawtooth). Then adjust the trimming potentiometer in question until the max. output level is reached and does not become higher even if the trimming potentiometer is turned further. Possible the the trimming potentiometer has to be turned back again a bit to find the correct position.
With the trimming potentiometer adjusted to max. sensitivity the linear amplification starts at about +0.1 control voltage (CV). We introduced this small dead range of about 100 mV to make sure that the VCA fully closes with CV = 0V.
It's possible to change the amplifications of the internal mixers used for the sum outputs (1-4, 1-8, 5-8) also to 1. Pay attention that then clipping/distortion may occur at the sum outputs. For this the 22k resistors R41 (Sum 1-4), R44 (Sum 5-8) und R51 (Sum 1-8) have to be replaced by 47k. As they are smd resistors sufficient experience with soldering/desoldering of smd parts is essential. And we have to point out that warranty is void if such modifications are carried out by the customer. The positions of the resistors are shown in the document A130_8_trimming_potentiometers_and_jumpers.pdf.
If multiple exponential VCAs are required module A-132-4 is recommended.

Notes: Module A-106-5 is a 12dB multimode filter that is based on the filter circuit of the Oberheim SEM module.

The filter is equipped with a band pass output and a combined low/notch/high pass output. For this output a control knob defines the relation between low and high pass signal. If both signals appear at the same level (i.e. middle position of the Mix knob) one obtains a notch filter. Otherwise the low or high pass signal predominates.

The module does not feature self-oscillation in contrast to most of the other filters of the A-100 system.

The module generates a distorted audio signal if the level control is set to about 50% (i.e. centre position) or more with A-100 standard signals like VCOs.

Notes: A-182-2 is a simple passive module that contains four changeover switches, which are used to connect or disconnect the sockets of the corresponding socket triplet:

- In the upper position of the switch the upper socket of the corresponding socket triplet is connected to the centre socket
- In the lower position of the switch the lower socket of the corresponding socket triplet is connected to the centre socket
- In the centre position of the switch the sockets are not connected

Each unit of the module can be used to switch between two signals or to interrupt/connect a signal. In the last case the third socket of the triplet is not used.

The module is fully passive and both audio or control signals can be switched.

Notes: The Intellijel/Cylonix RAINMAKER eurorack-format module provides a high-quality (96KHz sampling rate with 32-bit internal processing) stereo rhythmic delay and stereo comb resonator effect.

The stereo rhythm delay has 16 taps, each with its own resonant 2nd-order filter and granular pitch shifter. The filters have independently adjustable resonance and cutoff frequency, and can be set to either lowpass, bandpass, highpass or bypass operation. The filters are also capable of self-oscillation, enabling modal synthesis techniques. The granular pitch shifters have a range of 15 semitones up or 16 semitones down. Each tap can repeat at a rate value set in tap#'s in order to create regenerating echo effects. The feedback signal has a lowpass/highpass tone control and its own pitch shifter. The tap delay times can range from 0.1 millisecond up to a maximum of 20 seconds. The overall delay times can be set with the rotary encoder, the tap tempo button, or synced to an external clock.

The stereo comb resonator section has 64 time-delayed taps which are summed together. This produces a deep comb filter or resonating effect. At large comb sizes (long time delays) a multiple echo effect is produced. The density of the resonator can be varied from 2 to 64 taps. The tap with the longest delay time is fed back to the input. High feedback levels, with short comb sizes, produce "Karplus-Strong" types of plucked string sounds. The relative timing of the 64 taps are set according to one of 16 different preset patterns, which provide different resonator timbres or echo rhythms. The comb size can be set either with the rotary encoder, an external clock or through a transposable 1v/oct input voltage.

The Rainmaker module has extensive voltage control capabilities. Direct voltage control is available for the delay feedback level and tone, the global pitch shift for all delay taps, the comb resonator size, and comb feedback level. There are two assignable modulation inputs, which can be assigned to different parameters in each preset. A trigger input with assignable functionality can trigger built-in types of noise bursts, freeze the delay buffer, reverse the delay, randomize parameters, mute taps, and much more.

Notes: Cylonix and Intellijel have collaborated to bring you a very sophisticated and deeply complex Wavetable VCO. At the core of this module is very powerful FPGA board that he has pushed to the absolute max of its capabilities and crammed full of features. We wanted to create a module that really worked well in the modular context so there are a lot of modulation and control possibilities.

CHORDS
Oscillator 1 can be operated in a CHORD mode, which runs 8 copies of the oscillator in parallel with adjustable detuning, leading to very fat, rich waveforms. The oscillators have extensive modulation capabilities including audio rate (98KHz) Frequency and Phase Modulation (FM and PM) via external sources. Nonlinear combination processes allow the outputs of the two oscillators to interact to generate complex timbres and sonic textures.
There are 64 user selectable chords.

WAVEFOLDER
The SHAPESHIFTER module also includes the analog wave folder circuitry from
module to add analog warmth and metallic rasps to the digital oscillator output.
External signals can also be patched in.

PRESETS
The module includes a sophisticated preset mode where panel settings can be stored. There are 12 user-programmable preset slots and another 52 volatile slots that can be used as a scratchpad. These scratchpad slots are initialized to interesting presets on module powerup. The capabilities of the preset mode is not limited to mere passive storage of settings, however. In this mode the user can also step through, or sequence, the settings, either in order or randomly in response to pulses input to the external sync input. This gives the user the ability to generate complex sequences of sounds. The preset mode also allows the user to morph between the current panel settings and a preset providing a very powerful real-time performance tool.

SYNC
8 Different sync modes: HARD, SOFT, REV, HOLD, BUMP, 2=1, 1=2, OFF
with the ability to internally sync to a sub oscillator

PULSE
User selectable modes for the PULSE output: OR, AND, XOR, GLCH, +OSC1, EOC, +OSC2, -OSC2

MOD A modes: (audio rate modulation)
COMBO IN, SHAPE IN, PHASEMOD, VOCODER

MOD B options (all with CV control)

-Combo modes for OSC1 and OSC2:
NORMAL, RING, MIN, PONG, INLV, AND, XOR, GLCH
-Waveform TILT
-Chord mode overdrive
-Delay depth and FB
-Percussive mode decay time

Notes: Four channel voltage controlled Clock Divider/Multiplier with master Tap Tempo. Each channel can be synced to the tap tempo, to the channel above, or to an external clock. Each channel also has a reset jack.

With a Tap Tempo button and five sync'ed clock outputs, the QCD is a versatile head-of-the-chain "Master" clock module, and/or a complex rhythmic pattern generator.

Notes: Scales is an 8hp dual-channel note quantizer and step sequencer. Fundamentally, it takes an input voltage, quantizes it to notes in a user-defined scale, and sends that quantized voltage to an output, where you can use it as a melodic pitch source for oscillators or any other module that expects to see discreet note values at its input.

Scales goes far beyond the fundamental, allowing you unprecedented control of the pitches and intervals hiding inside your control voltages; turn LFO's into arpeggiators; random voltages into harmonic counterpoint; and unquantized external CV sequencers into chromatically tuned note sequencers.

Quantization can be locked to an incoming trigger. There are a number of trigger output options as well, ranging from no triggering (good for pitch shifting drones); through triggers that sync with either of the two outputs (or both); to a trigger or gate transmitted in sync with one sent to the module's TRIG input.

Shift:

Scales features two independent outputs, enabling you to create shifted harmonic intervals within your chosen scale using only a single pitch input. Using the SHIFT input you can modulate changes on OUT A and/or OUT B.

You can also use the shift input to switch between scales or to change the root of any existing scale pattern or split Scales into two quantizers - each conforming to a common scale, but fed entirely different voltage sources.

Sequence:

Scales also features a 128-step SH-101 style step sequencer (complete with storage for up to 35 fully programmable patterns) - allowing you to feed OUT B with sequenced notes and rhythm patterns, while OUT A continues to function as a standard pitch quantizer for external voltages. You can even sync the sequencer to quantizer events on OUT A.

Notes: Yet more bargain Buchla collabs from TipTop Audio with this dual voltage processor. Generate CV outputs algorithmically based on multiple inputs, allowing for some seriously complex modulation.

Supplier's Notes:
Model 257 Dual Control Voltage Processor consistsof two identical sections, each of which permits several applied control voltages to define a single output voltage according to the equation:

(Va * K) + ((Vb * (1-M)) + (Vc * M)) + Voset = V_out

The algebraic manipulations possible with this module include addition, subtraction, scaling, inversion, and multiplication. Also incorporated is the capability of using one control voltage (M) to transfercontrol from one applied voltage (V_b) to another (V_c).

Functions

- Attenuverter
Va is the voltage input a for attenuverter (left jack on the panel)
K knob can scale the incoming Va voltage either positively or negatively

- Crossfader
Vb is the voltage input b for the left side of the crossfader (second jack from the left)
+.5 switch adds 5 volts to the input of Vb
Vc is the voltage input c for the right side of the crossfader (fourth jack from the left)
M scales Vb from 1 to 0 based on the position of M knob
M scales Vc from 0 to 1 based on the position of M knob
The middle CV input at M/M can crossfade between Vb and Vc (third jack from the left)
The M knob and M CV added together to control crossfade position

- Oset
Voset Adds 0 - 10 volts to any combination of Va + Vb + Vc

- Output
Vout is the combined voltage of the attenuverter, crossfader and oset (right jack on the panel)

Notes: The Spherical Wavetable Navigator (SWN) is a six-channel synthesiser that makes it easy to create slowly morphing drones, polyphonic melodies, evolving sequences, and rich textures.

The SWN features six wavetable oscillators with independent pitch, level, and waveform controls. Six LFOs (Low Frequency Oscillators) can be used as modulation sources and/or envelopes, making it easy to add dynamic motion to your patch. Each channel is a full voice and can be "played" using the top row of buttons, the internal LFOs, or note-change detection on the 1V/oct jacks. The SWN ships with 12 three-dimensional (spherical) wavetables and an easy interface which allows you to record and edit custom wavetables from live audio. Open-source software for Mac, Windows, and Linux called SphereEdit can be freely downloaded and allows you computer to create, edit, and convert .wav files into Spherical wavetables to transfer into the SWN with an audio cable.

New firmware available which adds extra features, visit https://4mscompany.com/p.php?p=820&c=5 for details.

Notes: Duatt is a dual-channel active/buffered attenuverter and summing mixer. Each channel has a knob, which can function as a unipolar attenuator or a bipolar attenuverter, depending on the setting of its corresponding two-position polarity switch. It's a versatile and super handy utility module that will find its way into almost any patch you make!

Each input is normalled to a built-in +5V DC voltage source. With nothing plugged into the jacks, each knob controls a voltage range of 0 to +5 V or -5 to +5 V depending on the position of the channel polarity switch.

Channel A's output is normalled into the output of channel B for mixing duties, and channel A has a 2x voltage multiplier switch, allowing you to double the voltage sent into Channel A.

Notes: Proper creative stuff with this one. Lush, characterful stereo reverb with CV control, distortion, pitchshifting, a freeze button and more. Oh, and it's got user-customisable DSP firmware for good measure.

Supplier's Notes:
Desmodus Versio is Noise Engineering's take on a synthetic-tail generator reverb. In only 10hp, it features true stereo in and out, seven CV-controlled parameters, and three reverb modes. Desmodus Versio's feedback control sets the length of reverberation, from short echoes through infinite regenerations.

At its max, the reverb ducks when it receives input, useful for creating sidechain ducking and atmospheres for percussion. The different reverb modes offer even more sound options with clean, distorted, and pitch-shifting shimmer settings. The FSU button acts as a freeze and also creates some noise to stimulate the reverb when there is no external input.

Desmodus Versio isn't just a reverb, though: it's a DSP platform. Its firmware can be changed via USB, so users can load future firmwares onto it or develop their own with upcoming open-source support.

Notes: Tune is a multi-scale pitch quantizer. It features 11 scales ranging from chromatic to octatonic with everything in between. In addition, the bias control allows the user to transpose the melody to a different octave or starting note.

This functionality opens up every musical mode for each of its 11 scales and provides a performable control for transforming melodies on the fly.

Notes: Multi-function eight-channel LFO, joystick, movement recorder and drone oscillator that packs in lots more functionality than you might expect. A real modulation powerhouse in a compact format.

Supplier's Notes:
Erica Synths Black Joystick2 is 8 channel multi functional CV and sound source - joystick, movement recorder, distinct LFO and drone/noise oscillator. It provides great interaction with the modular system and allows to develop unconventional modulation patterns instantly.

Notes: Third-party clone of the open-source Mutable Instruments Plaits oscillator/sound source. All the same functionality in a compact 8hp format with full-size knobs for the key functions.

Supplier's Notes:
Functionally identical clone of the Mutable Instruments Plaits. Beehive strikes a nice balance between size, reducing 12hp down to 8hp, and playability by offering full size knobs for the four main functions. Beehive also retains the same depth of the original module at 25mm. This module uses After Later's new aluminum knobs which have a nice non-slip texture and allow for more finger space over the standard 1900H Davies knobs.

Notes: 2HP narrow version of the A-180 multiples module. It is a passive signal splitter suitable for audio or CVs. Two sets of four jacks are interconnected, by placing a solder bridge you can connect all eight jacks.

Notes: 'Akemie's Castle' is a dual voltage controlled oscillator with authentic 4 Operator digital FM using 'new-old-stock' Yamaha IC's for audio signal generation.

Each of the 4 operators feature independent waveform selection, frequency multiplier and level control via direct panel operation and voltage control. Operators can be combined in various ways across both oscillators, which together with independent feedback control on each VCO, offer an extremely wide palette of sounds.

Oscillator A also features a chord mode providing a range of up to 5 voice chords and voltage controlled inversion.

Notes: The Buff Mult is a buffered multiple with LED indicators to show positive and negative voltages. Using wide bandwidth opamps, it functions as a dual 1-to-3 or a single 1-to-6 mult for audio, video, or CV signals.

Notes: Highly sought-after utility tool that always sells out quickly. Full colour display gives visualisation as an oscilloscope, spectral analyser, spectograph, tuner and more. Waveform and clock generator options too.

Supplier's Notes:
The Ultimate Eurorack Utility Module (and a whole lot more!)

The DATA is a digital platform for testing, measurement, and signal generation in Eurorack modular synthesis systems. It is a modular tool kit, with functions applicable to any system and style.

Use the DATA's scope to view the interactions between your control voltages and audio signals, allowing you to master your modules by understanding their voltage ranges, control shapes, and parameter responses. Use the DATA's dual waveform generator to dial in a precisely scaled LFO for CV control, or use the waveform's frequency "note mode" to effortlessly make dyads (two note chords). Use the DATA's clock program as a master clock or to divide or multiply an incoming clock signal, sending four different clock outs to gate modules directly or as control to sequencers.

The possibilities of the DATA are basically unlimited; with the included microSD you can update the DATA's firmware and we can continue to refine and create new programs.

Notes: Rossum Electro-Music Software Architect Bob Bliss (who also, as it happens, fathered E-mu's famed "EOS" Emulator Operating System) has created Panharmonium, a unique music and sound design tool that analyses the spectral content of any audio signal and uses that analysis to drive a bank of from 1 to 33 oscillators. Depending on various control settings, Panharmonium can accurately reproduce the input spectrum in real time or modify it in a multitude of wildly creative ways. All with an interface whose immediacy encourages performance and interaction.

Panharmonium input can be anything from a single oscillator to an entire mix (including vocals). From dense, swirling pads and drones that evolve with the input's changing spectrum, to clock-syncable spectral arpeggiation, to as-yet unnamed harmonic effects, Panharmonium opens up an entirely new world of sonic possibilities.

Additionally, Panharmonium can take a snapshot of an instantaneous spectrum and use that as a complex harmonic oscillator, which can then be modified and modulated by all of Panharmonium's other controls.

Panharmonium accomplishes its magic though a combination of functional submodules:

Spectral Analyser:

The Spectral Analyser provides tools for defining the analysis process.

- The Slice parameter sets the rate at which the incoming audio is transformed to spectral data. It can be set by the Slice and Multiplier controls, the Tap button, or by an external clock signal. Very short slice times result in real-time spectral data, while longer times can create rhythmic spectral patterns.
- The Centre Freq and Bandwidth controls (and associated CV inputs and attenuverters) control the range of frequencies to be analysed. The Bandwidth control allows the selection of narrow to wide pass bands on the left side of the pot and narrow to wide notches on the right side of the pot. The ability to sweep the frequency and modify the bandwidth under CV control opens up a wide range of sonic effects.
- The Freeze button lets you freeze the spectral integrator, sustaining the currently analysed spectrum.

Spectral Modifiers:

These controls allow you to creatively modify the analysed spectra.

- The Voice parameter lets you select from 1 to 33 oscillators to resynthesise the spectrum.
- The Blur parameter (and associated CV input) is a spectral lag processor that controls how quickly the spectrum can change.
- The Feedback control (and associated CV input) lets you route the re-synthesised audio back into the entire processing chain for subtle or dramatic feedback effects. At its max, the output becomes self-sustaining, even if the input is removed.

Oscillator Bank:

The Oscillator Bank resynthesises the analysed spectra.

- The Waveform parameter selects the oscillators' waveform. In addition to the usual sine, triangle, sawtooth and pulse waveforms, two special crossfading sine and sawtooth waveforms are included.
- The Freq control lets you tune the oscillators over a +/-7 semitone range. The frequency is further controlled by the 1V/Oct input and the FM input and attenuverter.
- The Octave control, not surprisingly, shifts the pitch of the output by octaves.
- The Glide parameter sets the amount of polyphonic glide (i.e., each oscillator has its own glide circuit).
- The Mix control (and associated CV input) sets the balance between the original input audio and the resynthesised audio.

Optional Functions:

A number of optional functions can be selected by using the Output Mode and Tap buttons.

- Holding the Output Mode button and adjusting the Slice control enables Drums Mode, which optimizes the spectral analysis for drums and other percussive inputs.
- Holding the Output Mode button and adjusting the Centre Freq control allows you to instead set the lower frequency of the analysis range.
- Holding the Output Mode button and adjusting the Freq control enables Spectral Warping. In contrast to conventional frequency adjustment, where the harmonic relationships between the spectral elements are preserved, Spectral Warping shifts the harmonic elements individually, producing a variety of clangourous, swarming textures.
- Holding the Tap button and adjusting the Freq control quantizes the resulting frequency adjustments to semitones.

Spectra Memories and Presets:

Panharmonium provides 12 user Spectra memories and 12 user Presets (in addition to 12 each factory memories).

- The Spectra memories let you store up to 12 frozen slices. When selected, a spectrum (up to 33 oscillators wide!) replaces any live input and can have its pitch controlled by the 1V/Oct input and FM controls.
- A Preset is a snapshot of all of the module settings, along with the value of any CVs present at the moment the preset is saved.

Panharmonium is 26HP wide and 25mm deep.
Power requirements (max): 140mA +12V, 30mA -12V. Reverse polarity protected.

Notes: Another cracker from Xaoc, the Timiszoara is a take on digital multi-effects with stereo in and out, an intuitive interface and CV control of effect parameters. Big power with 176 factory programs.

Supplier's Notes:
Timiszoara is a stereo, Eurorack compatible, voltage-controlled multi-effect signal processor based on the popular Spin Semiconductor FV-1 DSP chip. It features a full stereo signal path with two adjustable audio inputs, two outputs, and a stereo voltage-controlled wet/dry mixer. In addition, there is a microSD memory card slot on the front panel that allows for loading factory and custom effects without any restrictions or copyright protection, which means you can use many effects available on the Internet and even create your own.

Effect programs are organized in banks of 8 and can be selected using a rotary encoder, as well as CV and trigger signals. Timiszoara features a crisp OLED screen that displays the program parameters and its name. It also facilitates navigating the list of banks. Up to three parameters per effect can be controlled from the front panel with illuminated slider potentiometers and dedicated CV inputs.

Xaoc Devices have prepared quite a few banks of algorithms (176 in total) that cover most effects needs: delays, reverbs, filters, modulation effects (such as choruses and flangers), pitch shifters, and, of course, shimmers (no multi-effects unit would be complete without its share of those). However, Xaoc Devices wanted to ensure that users had access to some more adventurous programs, so some special banks have been created to allow you to take a walk on the wild side.

For detailed description, please refer to the manual.

Notes: Module A-199 is a spring reverb module. The reverb effect is electronically simulated by means of 3 spiral springs. Spring reverb systems have a very characteristic sound that is based on the (insufficient) mechanical properties of the springs like signal delays, audio resonances, limited frequency range, acoustic feedback behaviour, sensitivity to mechanical shocks and others.

The 3-spring system used in the A-199 ensures a "dense" reverb because of the different properties of the three springs.

The A-199 implies some special features that are not self-evident for spring reverb units:

The reverb signal can be fed back to the input using the Feedback control. Even self-oscillation of the springs similar to the self-oscillation of filters is available. The feedback loop can lead even via external modules like VCA, VCF, phaser, frequency shifter, vocoder, distortion/waveshaper, ring modulator and others. In this case the reverb output of the A-199 is connected to the input of the external module(s) and the output of the external module(s) is fed back to the Ext. Feedback In socket of the A-199. This socket contains a switch that interrupts the internal feedback loop as soon as a plug is inserted.

Another feature is the Emphasis control. This enables the adjustment of the accentuation of middle frequencies (around ~ 2kHz).

With the Mix control the relation between original and reverb signal appearing at the mix output is adjusted.

Using all these features very extreme and unusual effects can be generated with the A-199.

Notes: 32 unique audio effects arranged in 4 banks of 8 effects. Three effect controls plus analog Dry/Wet control with dedicated CV input. High quality stereo signal pass. Assignable CV input to effect controls or to Sample Rate reducer (changes internal clock). Four user storable presets - stores selected program and all three controls. Spin FV-1 based.

The last used effect, assigns and presets are always remembered.

32 effects are simultaneously available, but FX AID can be reflashed with other user selected Happy Nerding effects in any order. Also the possibility to run freely available third party effects will be added too.

Reflashing procedure is quite easy: playing 40 sec long "wav" file of line level amplitude to CV input.

Reflashing mode: hold both buttons for 10 sec.

Please note the reverse CV operation of the Dry/Wet control: positive CV crossfades from Wet to Dry, and negative CV crossfades from Dry to Wet.

By default it runs on 32.77 kHz and, if sample rate reduction assign is used, this sample rate can be decreased down to 150 Hz or brought up to 48 kHz.

Notes: VCO:

- Tune: manual tune control (with an internal jumper the range can be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)
- Oct: range switch -1 / 0 / +1 octave
- Mod: modulation depth (attenuator wired to the Mod. socket)
- Dest: switch that is used to address the modulation to frequency modulation (position FM) or pulsewidth modulation (positon PM), in centre positon no modulation
- PW: manual pulsewidth control for rectangle waveform, PW can be also modulated by the Mod. input as mentioned above
- Wave: waveform switch (sawtooth / off / triangle), the sum of the waveform chosen by this switch and the rectangle is fed into the VCF (to turn the rectangle off the PW control has to be set fully CCW or fully CW)
- 1V/Oct. (socket): external CV input for VCO frequency (1V/octave)
- Access to internal bus CV (via jumper, optional, please remove the bus jumper if this feature is not used to avoid unwanted frequency modulation as then the unused CV line of the bus works as a kind of antenna)
- Triangle core VCO, frequency range about 32Hz ... 8kHz

Balance unit:

- The balance unit is made of two VCAs which are controlled by the sum of manual Balance control and the balance CV input in the opposite direction.
- The audio input of VCA1 is hard-wired to the VCO output, audio input 2 is connected to the socket Ext.In.
- The output of the balance unit is used as audio input for the VCF
- Bal.: manual balance control, fully CCW the internal VCO is used, fully CW the external signal (Ext.In) is used, at centre position both signals have about the same level
- CV Bal.: CV input for balance (range about 0...+5V)
- Ext. In: external audio input for VCA2, about 5 Vpp level required for similar loudness as the internal VCO
- This socket is normalled to the internal VCO suboctave f/2 signal (rectangle with half the frequency), if no external signal is applied the suboctave signal is used as the second signal for the balance unit

VCF:

- 24 dB low pass
- Frq: manual frequency control
- FM1: frequency modulation depth (attenuator wired to the VCF FM1 socket, the socket is normalled to the internal Envelope signal and then FM1 controls the modulation depth of the internal envelope applied to the filter)
- FM2 (socket) : second CV input for VCF without attenuator (about 1V/octave), can be used e.g. for VCF tracking by connecting the same CV which is used also for the VCO frequency
- Res: manual resonance control (up to self oscillation)
- If the VCO is turned off (waveform switch = centre position, pulsewidth control = fully CCW or CW) and the VCF resonance is set to maximum the module can be used as a sine oscillator, the tracking at socket VCF FM2 is about 1V/octave (not as precise as the VCO but much better than most other filters)
- ~ 11 octaves frequency range (~ 10 Hz ... 20kHz)

VCA:

- Gain: manual amplitude control (initial gain), can be used to open the VCA without envelope signal
- VCA (switch): used to switch between gate and envelope as control signal for the VCA, in centre position the VCA is not controlled by envelope or gate
- Note: when gate is used the VCA is controlled directly by the gate signal (i.e. hard on/off), this may lead to clicking noise under certain conditions (especially with low VCO/VCF frequencies)
- Special control scale: exponential scale in the range from about -20dB to -80/90dB, linear scale from about -20dB to 0dB
- Remark: this special control scale results in a loudness behaviour that is a bit different from pure linear or exponential VCAs
- Out: audio output of the module (= VCA output)

Envelope:

- Gate (socket): Gate input (min. +5V), can be normalled to the bus gate signal by means of a jumper
- Att: manual control for Attack
- D/R: manual control for Decay/Release
- Env. (switch): used to switch between A/D, ADSR and A/R mode of the envelope generator, in centre position (ADSR) the sustain level is fixed to about 50%
- Envelope (socket): envelope output (about +10V)
- CVT (socket): CV input for time control, by means of two internal jumpers one can select which time parameters are controlled by the CVT input (e.g. A only or D/R only or A/D/R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question)
- Envelope LED display
- Attack time range: ~ 1ms ... 5 sec (can be extended by using the CVT input)
- Decay/Release time range: ~ 1ms ... 15 sec (can be extended by using the CVT input)

Notes: Really impressive sequencing module with a few clever tricks up its sleeve. Eight tracks of CV/gate with built-in effects (quantise, swing, arpeggiator, etc) for processing MIDI or CV inputs. Real-time recording, step sequencing, looping and much more.

Supplier notes:
Hermod brings together a powerful step sequencer, a CV looper, a real-time effect processor, LFO generators and a complete bi-directional MIDI-USB-CV input/output interface.

Record a performance at any time thanks to the CV inputs, the USB HOST, the USB DEVICE and the MIDI input. Create and edit your tracks with the STEP mode and its piano roll and automation view. Generate crazy patterns with the randomization tool.

Hermod is polymetric, it means that each track can have a different length, from 1 step to 64 steps. Moreover, you can zoom in to increase the resolution of the step sequencer (up to 512 steps).

Polymorphic tracks:

Thanks to Hermod architecture, a track can be a simple mono CV/GATE voice, but can be easily configured as a polyphonic track (up to 8 voices), a CV/GATE + velocity + aftertouch track, a modulation + clock track... in order to perfectly fit your Eurorack system!

Sequences and Projects:

The 8 tracks are grouped into one of Hermod's 8 sequences. Every sequence is totally independent and contains a new set of tracks to be played with, for a total of 64 tracks in a single project.

Dynamic effects:

All the fun in Hermod resides in its effect system, allowing you to transform input signals, whether it's MIDI or CV. You can stack on each track up to 8 real-time effects: Quantize, Swing, Arpeggiator, Ratchet, Random, Euclid, Glide, Harmonizer, Delay, Chance, Scale, LFO... Experiment with the effects position and parameters to generate eccentric melodies!

MIDI-USB-CV interface:

Full connectivity: control Hermod with plug-and-play midi USB devices, midi keyboards, computers or other Eurorack CV systems.

Hermod is also a great midi hub, allowing you to sequence midi synthesizers/drum machines and computer's virtual instruments. Of course, Hermod can be perfectly paired with Pyramid or other hardware and software sequencer, in order to benefit from its CV/GATE outputs.

With Hermod's rock-solid clock, this module becomes a great synchronization tool for all your setup! Thanks to its powerful CPU, even when synced/slaved, Hermod allows an ultra-low latency to make the perfect link between the digital world and the analog world.

The package includes:

- Hermod "Modular Brain" Black Edition
- 1GB micro SD card + SD adapter
- Power ribbon cable
- User guide (English)

Notes: The Ensemble Oscillator is a unified polyphonic voice of sixteen complex oscillators combining additive, FM, phase-distortion and wavefolding synthesis techniques in new unorthodox ways. By quantizing the oscillators to scales or series of harmonics, the Ensemble Oscillator allows you to explore the sonic boundary between musical chords and rich evolving textures. Easily create a wide variety of sounds ranging from aggregates of pure sine waves to pulsar synthesis or pristine harmonic tones and lush wide chords to rich dirty drones and rumbling glitches. Custom scales can quickly be "learned" and saved using a CV keyboard or by manually entering notes with the controls.

The Ensemble Oscillator is designed by Matthias Puech and 4ms Company.

Notes: Based on a new digital hardware platform, the Spectraphon is a powerhouse spectral oscillator, capable of everything from analogue-style dual complex oscillators to FM and much more.

Supplier's Notes:
The Make Noise/Soundhack Spectraphon is a dual Spectral Oscillator coded by Tom Erbe of Soundhack. It uses real-time spectral analysis and resynthesis to create new sounds from those that already exist. It is inspired by classic electronic musical instruments of the past, including spectral processors, additive synthesis, vocoders, and resonators especially the Buchla 296 and Touche, but it takes a physical form more resembling the classic analogue dual complex oscillator in the lineage of the Buchla 259 and the Make Noise DPO.

The Spectraphon is the first module to be built by Make Noise on its new digital hardware platform. This hardware, engineered by Jeff Snyder and Tony Rolando, provides more i/o at higher resolutions, and a lower noise floor than we have ever had access to in a digital module, allowing us to unleash Tom Erbe's DSP code to a previously unattainable degree.

The Spectraphon has two nearly identical sides, A and B, which oscillate in one of two ways: Spectral Amplitude Modulation (SAM), or Spectral Array Oscillation (SAO). In SAM, instead of oscillating at all times like an analogue VCO, sound at the Spectraphon's input is used to modulate the amplitude of a set of harmonics. In SAM the Spectraphon can be sequenced and frequency modulated like any VCO. At any time the current spectrum can be used to create an Array for later use in SAO mode where the Spectraphon oscillates at all times, with the spectrum at the Odd and Even harmonic outputs being drawn from those stored Arrays.

The Slide and Focus controls are mode-dependent: in SAM, they determine how the Spectraphon responds to sound at the input for Spectral AM, while in SAO, they are used to modulate the Array.

In either mode (SAM or SAO), the Partials control works as a combined amplitude and timbre gate for the Odd and Even harmonic output and the FM Bus will create high definition internal frequency modulation from the opposing side of the Spectraphon. The two sides can also interact via the internal FM Bus, the Follow and Sync modes, and by patching them together.

Notes: Mult is a 2 input, 6 output signal splitter. Channel 1 is normalled to channel 2 when no cable is present, allowing the user to split an input signal six ways, or two input signals with three outputs each.

Notes: A really clever take on looping, falling somewhere closer to granular synthesis depending on how you use it. Layer and repeat multiple sound sources to create textures, chords and unique timbres.

Supplier's Notes:
Endless Processor is a dual-channel infinite sound sustainer machine.

Put your favourite instruments, unique timbres, or field recordings - virtually any sound - and make it last forever.

It is not a looper in the usual sense - Endless Processor resynthesizes your sounds to create a perfect clickless stream while preserving the timbral and tonal character of the original.

Endless Processor always listens to audio input and keeps a most recent history. Experiment with sustaining little bits of a sample or make a massive wall of sound with the ability to select how much memorized audio to process.

Stack your sounds to create harmonies, textures, or drones with 5 layers per channel. Each layer can be re-processed or cleared while keeping other ones in place. Set fade-in and fade-out time to quickly or gradually introduce a new layer or remove the existing one.

Additional controls will help you to adjust or shape a channel volume (think built-in VCA).

Notes: The 2hp VCA is a dual, linear VCA. It uses the renowned 2164 SSM architecture, giving it extremely low distortion and high quality audio outputs. With a CV input attenuator, and DC-coupled inputs this is your new go-to module for voltage controlled amplification of audio or CV.

Notes: Module A-156 is a Dual Control Voltage Quantizer. A quantizer converts a continuous control voltage in the range 0...+10V into a stepped output voltage in the same voltage range (i.e. only certain voltages occur). Normally 1/12 V steps are used to obtain semitone steps. Quantizer 2 of the A-156 allows has more sophisticated quantizing modes like major scale (i.e. only voltages corresponding to the major scale), minor scale, major chord, minor chord, fundamental + fifth and addition of seventh or sixth when chords are selected. Only those voltages appear at the CV output which comply with the selection rule (e.g. minor chord with seventh). The mode setting of quantizer 2 is done with 3 switches (1-0-1 type with middle position). From the factory quantizer 1 is working in the semitone mode. But there is a jumper on the pc board that can be changed so that even quantizer 1 uses the same scale as quantizer 2.

For each quantizer the following in/outputs are available:

- Control voltage input (CV In): The input for the continuous voltage to be quantized
- Control voltage output (CV Out): The output of the quantized voltage
- Trigger input (Trig.In): If this jack is left open the quantizer is working permanently. If a rectangle voltage is applied quantisation happens only at the rising edge of the signal (e.g. from an LFO or MIDI-to-Sync interface). Thus the quantizing can be synchronized with other events
- Trigger output (Trig.Out): Whenever a quantisation happens (i.e. a new voltage is generated at the CV Out) a positive pulse occurs at this output. It may be used to trigger an envelope generator (ADSR) or for triggering other modules (sequential switch A-151, trigger divider/sequencer A-160/161, trigger delay A-162, ...). If none of these functions are used the jack is left open

On top of that the A-156 is provided with a common transpose CV input having an additive effect on both quantizers. This input is quantized in semitone steps. A typical application is the transposition of a sequence generated by the A-155 by a second control voltage (e.g. coming from the MIDI-CV interface A-190).

Typical applications:

- Quantizing the CV sequence generated by an A-155 (semitone, only major scale, only minor scale and so on)
- Quantizing the voltage coming from the Trautonium Manual / Ribbon Controller A-198, Theremin A-178 or Light-to-CV module A-179 to get accurate semitones or major/minor scale tones
- Arpeggio-like effects with LFO, random, noise, envelope generators as CV sources (for negative or symmetrical voltages an offset must be added, e.g. with the offset/attenuator module A-129-3, to obtain positive voltages for the A-156 input)

Notes: Triplatt is a three-channel active/buffered attenuverter and summing mixer. Each channel has a knob, which can function as a unipolar attenuator or a bipolar attenuverter, depending on the setting of its corresponding two-position polarity switch.

Each input is normalled to a built-in precision +5V DC voltage source. With nothing plugged into the jacks, each knob controls a voltage range of 0 to +5 V or -5 to +5 V depending on the position of the channel polarity switch. Outputs A and B are also capable of a range of 0-10 / -10 to +10 when using the special function switches.

Each output is normalled to mix into the output of the channel below, making it possible to do sub mixes in groups of two or three.

In addition, each channel has a "special function" switch to alter its input voltage in a specific way. Channel A has a 2x voltage multiplier switch, allowing you to double the voltage sent into Channel A. Channel B has a +5V switch, allowing you to add 5V to whatever voltage is sent into Channel B. Channel C has a mute switch, allowing you to completely turn off the signal being sent into Channel C.

Notes: LINK is the module that bridges Eurorack to destop mixers - it has 5 sections that attenuate Eurorack signals to line level signals and sends them to 6.3mm jacks for quality connection to the mixer.

Notes: Delay is a flexible, full-featured delay audio processor. CV over all parameters provides dynamic access to its nuanced controls. The feedback path ranges from slapback to infinity, allowing for wild permutations of the original signal.

With delay times from milliseconds to nearly two seconds, Delay is sure to find a use in every patching situation. Add subtle echo to a melodic line, or crank up the feedback and hear a bed of layered sounds to bury your listeners in.

Notes: nRings

This is a new build of a micro version of Rings from Mutable Instruments. MicroRings, also called NanoRings, retains all the same functionality as a full-size Rings module.

The module is fully assembled, tested, and calibrated. Eurorack power cable is included.

These modules use tall bushing potentiometers to offer a more stable feel.
