Notes: The DIODEFILTER is an adaption of the well-known diode ladder filter that became most popular by Roland's TB-303 bassline. And here it is for the AE modular!

Notes: The module was named Kuzmin Filter in the past as a tribute to the developer of the Polivoks, Vladimir Kuzmin. For certain reasons, the module will now be called GRUNGE Filter (due to the sound), with the circuitry remaining unchanged.

The Polivoks was a Russian synth that was produced between 1982 and 1990.This module is the AE version of the filter that gave the Polivoks a unique, rough sound.

Beyond the basic design, this filter offers some additional features:

Two different resonance characteristics, hard and soft
An FM function, that adds the input signal to the modulation of the filter
An optional overdrive for the output, making the sound even more rough and untamed.

Notes: Unique, vintage reverb sound.

The SPRINGREVERB module brings the unique sound of this quite old (introduced in the 60's) technique for creating reverbs to the AE modular.

The reverb works by sending the audio signal to a set of 3 springs; at the other end of the springs the sound is picked up by a transducer, converting the mechanical movement of the springs back into an electrical signal. When the audio signal arrives at the end of the springs, the waves are reflected several times; these reflections create the reverb sound.

The spring "tank" (a metal box containing the springs and transducers, size approx. 24 x 9 x 3.5 cm) is connected externally by a cable.

The product contains all components: The module itself, the spring tank and the connection cable.

Note: The sound of a spring reverb is quite unique and has a strong vintage character; if you are looking for a more "clean", natural sounding reverb please take a look at the MULTIFX module.

Notes: With the STOMP-IO module, you can integrate guitar effect pedals and similar devices into your AE modular system! For output (send) and input (return) return there is a mono minijack socket; two minijack to 1/4" socket adapters are included as effect pedals usually work with the latter ones. Send and return levels can be controlled with separate knobs.

Notes: XMIX is a swiss knife for signal mixing and attenuating, offering four(!) mixers and two attenuators in a 1U module. It is designed especially with very small AE systems in mind.

You get:

A three channel mixer "A" with knobs
a passive mixer "B" with four channels
two four-channel mixers "C" and "D" with full level / one-third-level inputs
two attenuators with seven different attenuation levels

All mixers can be used / switched for audio and CV signals.

Notes: The Cali oscillator is a new and improved version of the classic Buchla 258 wave shaping oscillator with an additional pulse width modulated output. The oscillator features the classic Sine to Square and Sine to Saw wave shaping with dedicated CV control. The Cali Oscillator differs from previous versions of the 258 in that it has a 3-way position switch rather than 2-way. This new middle position features a bonus waveform that will shape from a pulse into a kind of triangular trapezoid shape. The shaping control is more unpredictable in this middle position and the switch reacts to body contact when the wave shape is set low - it can be thought of as an extra bonus waveform, great for producing glitchy sounds! There are dedicated inputs for linear and exponential FM and the Cali also adds a Pulse output with it's own width control and PWM CV input. The behaviour of the pulse output can be affected by the position of the waveform switch and wave shape control. The module features Coarse and Fine frequency controls and an LFO mode, LFO range is accessed via an LED pushbutton that also acts as the LFO speed indicator - the button will light up when the waveform moves through its positive cycle. Because the wave shape modulation is independent of pitch this oscillator is very useful for creating complex timbres whilst retaining musical pitch.

Features

Sine to saw/square waveform output with cv over wave shaping

Pulse output with voltage controlled PWM

Linear FM with attenuator

Logarithmic FM with attenuator

Bonus 'trapezoid' output

Coarse & fine controls with LFO mode

Includes power supply isolation on frequency controls

Notes: Gorgeous vintage-style through-zero FM here, featuring five simultaneous waveform outputs, pulse width modulation, soft sync and a dedicated LFO mode.

Supplier's notes:
The EN129 Thru Zero Oscillator is an all analogue triangle-core VCO specialising in frequency modulation. Analogue through-zero FM modulation produces a wide array of timbres particularly useful for bell like or percussive sounds. Through zero linear frequency modulation can be precisely dialled in thanks to a dedicated CV input attenuator and through zero offset control. Logarithmic FM is also available via it's own dedicated input with attenuator and both FM inputs have an LED to indicate incoming voltages. Simultaneous analogue wave outputs include: Sine, Triangle, Sawtooth, Square and Pulse wave with Pulse Width Modulation. The PWM control goes to zero at either end of it's range, which is very useful for creating rhythmic sounds with voltage control. Furthermore the PWM control doubles up as wave shape modulation for the Sawtooth wave - gradually altering the waveform until it shifts half a cycle. The EN129 features Coarse and Fine frequency controls as well as an LFO mode. LFO range is accessed via an LED pushbutton that also acts as the LFO speed indicator - the button will light up when the waveform moves through its positive cycle. A new addition of a Soft Sync Input allows the phase of the oscillator to be controlled by an external oscillator for an even greater range of timbres.

The EN129 is based on the pioneering work by Douglas Kraul and Bernie Hutchins. You can read the original Electronotes article from 1981 that the design is based upon here.

Notes: The Dannysound Dynamics is a compressor / expander originally designed to process drums but, like most processing devices, it can be used for a wide variety of applications.

The module comprises of:

Compressor / Expander
Sub Bass Enhancer
3 Band Inductor-based EQ
Harmonic Exciter

The compressor / expander section uses a discrete transistor-based circuit that allows for soft clipping when overdriven.

The envelope detector is known as a feedforward type of circuit; taking its input from the signal before it goes to the compressor rather than after. This type of circuit is known for having fast attack times.

The Sub Bass enhancer has its own compression circuit that "ducks" the initial transient. This allows the sub bass to be increased without distortion on the transient peaks, increasing the overall level.

There is a MIX control to allow the unprocessed signal to be mixed back in with the processed signal.

The 3 band EQ is an inductor based LCR design. After Dannysound tryed out various EQ topologies, this was the design that sounded the nicest. When overdriven it gives a nice "bite" to the sound, and it has a certain characterful charm that's hard to put into words. The controls have a response that are subtle to begin with and get more pronounced as the controls are increased.

The Harmonic Exciter adds a little distortion to the high frequencies, which bring out the sparkle of cymbals or the snap snare drums. The operating bandwidth can be switched between Low (snare drum snap) or High (Cymbals sparkle).

There are inputs for side chaining and control with an external envelope as well as an envelope out to make the envelope detector output available to drive other modules.

It also features separate inputs and outputs for the Compressor / Expander and EQ sections, so they could be used as 2 separate modules.

Features:

Compressor/ Expander
Sub Bass Enhancer
3 Band Inductor-Based EQ
Harmonic Exciter
Envelope In/Out
Sidechain Input
Seperate In/Out for Compressor, Expander and EQ-Section

Notes: The updated "Skiff friendly" design of the mml filter now features bipolar "Attenu-verters" for the cv controls as well as an all new red mode!

This new mode activates a feedback distortion circuit capable of actually changing the pitch of the notes coming in to the filter in a musical way that adds instant variety to acid basslines, creates weird and strange alterations to drones or adds some nice overdriven distortion to whatever goes into it!

The multi-mode ladder (mml) filter is based on the classic transistor ladder low pass filter by dr. Robert a. Moog. This filter updates the classic 4-pole ladder design to provide band pass and high pass filter responses as well as the traditional low pass filter. There are 2 bipolar controls with attenu-verters for the cut-off frequency plus a cv input for the resonance.

The core of the circuit features a fully discrete transistor design with an op-amp buffered output, this allows soft saturation of the input signal to get the classic overdriven tones of the ladder filter. A bass compensation circuit has been included to retain the bass response in low pass mode when the resonance is increased. The bass compensation also helps to improve the response of the high pass filter.

The red mode is activated/de-activated by holding the mode button for 0.3s. In this mode the filter cut-off, input volume and resonance all interact and the effect is to produce alterations to the incoming frequencies. The pitches of the audio coming into the filter also affect the alterations as well selecting between low pass, band pass and high pass filter modes whilst in red mode.

Features

Low pass, band pass and high pass modes.
Red mode feedback distortion.
CV controlled resonance.
Added low frequency compensation.
Soft saturation of input.
2 x bipolar attenuverter CV inputs.

Notes: The Timbre is a 6HP Eurorack module based on the wave folder section of the Buchla 259 oscillator as implemented in the Music Easel.

The wave folder adds extra harmonics to input signals that have low harmonic content to create rich and interesting timbres. Typical input sources to use would be Sine and Triangle waves but you are welcome to try other sources as well! The Dannysound Timbre adds an extra input to the Buchla design to allow 2 oscillators to drive the wave-folder simultaneously - this dramatically increases the range of possible tones that can be generated and allows the folder to go wild!

Features:

Osc1 / Osc2 Mix - Adjusts the mix between the Oscillator 1 and 2 inputs, also acts as an attenuator if only one input is used.
Timbre Control - Adjusts the overall amount of wave fold
Timbre CV - Bipolar (attenuator) controls the Timbre CV input
Symmetry - Adds an offset to the input so that the top half of the wave begins to fold earlier
Blend - Mixes between the clean and effected sound

Power consumption: 46mA at +12V and 48mA at -12V

Depth: 25mm

Notes: The Looping VC-ADSR is a 4-stage, loop-able, envelope generator based on the ENVGEN 8C IC from Electric Druid. The individual sections of the Envelope (Attack, Decay, Sustain, Release, Level and Time) can all be individually controlled via CV.

The module has 5 MODES of operation that can be selected via the pushbutton LED switch with the status indicated by the five LEDs above:

Normal Envelope - Gate signal at the GATE/TRIG input, fires the ADSR.
Trigger Mode - Trigger signal at the GATE/TRIG input fires the AD portion of the envelope. The sustain control determines the final value the envelope rests at after the decay portion has ended.
Gated Looping Envelope - ADSR loops whilst gate signal is high.
Looping Envelope - ADSR loops regardless of gate signal.
LIN response (Hold switch to select between LIN/EXP Mode) - Sets the envelope response to be Linear. The response is Exponential when the status LED is off.
When the envelope is looping, all 5 controls affect the output. Attack and Decay operate, as one would expect. The Sustain control sets the minimum voltage the decay part of the envelope will decay to. The Release sets a release time from the end of the Sustain period to the beginning of the next cycle. When the Sustain is set to 0 you can use the Release control to add a delay between the Attack and Decay cycles.

In Normal Envelope mode the Sustain CV input can be used with an LFO source to add amplitude modulation that gradually increases as the Envelope transitions from the Attack/Decay part of the envelope into the Sustain part. The Level CV is also a useful point for amplitude modulation or can be used for Velocity Sensitivity via CV.

The Time CV is set so that increasing voltage shortens the overall envelope time to better mimic the sounds of percussive instruments.

Features:

5 Modes of Operation: Gate Input ADSR, Trigger Input ADS, Gated Loop, Constant Loop and EXP/LIN Envelope Responses
CV over: Attack, Decay, Sustain, Release, Level and Time
Works with Gate or Trigger Signals from +5V to +12V
CV Input Range 0V to +10V
Output CV Range 0V to +10V

The BXx2 is a dual channel preamp, EQ and mixer based on the classic Boss BX series mixers. With the inclusion of both input gain and level controls, each channel can be overdriven, producing the signature saturated and lively sound the BX mixers are known for. The EQ controls provide the channels with simple but great sounding high and low shelf EQs for emphasising and shaping sounds and an additional 'Aux' input allows another mixer or extra sound source to be chained in.

Input gain controls

Sets the input gain of the channel preamp. Higher settings will cause source to overdrive the channel.

Inputs

In 1 - Input to channel 1 of the mixer.

In 2 - Input to channel 2 of the mixer.

Aux - Auxillary mix input for chaining with another mixer or extra source.

Fixed gain (-6dB).

EQ High

Sets the gain of the fixed high shelf EQ. Boosts high frequencies when set above 12 o'clock and cuts when set below.

EQ Low

Sets the gain of the fixed low shelf EQ. Boosts low frequencies when set above 12 o'clock and cuts when set below.

Level

Sets the channel level in the mix. Use level controls to trim back volume when overdriving the preamp.

Output

Audio output producing the mix of the 3 inputs.

Technical specifications

Power: +12V 10mA / -12V 10mA
Size: 8HP
Depth: 32mm

The BXx2 was designed in collaboration with Feedback Modules and is based on their single channel 'PRE BX' module.

Notes: ***B-STOCK: Slight dent om the edge, otherwise in perfect condition***


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: R2M is module 1 of a pair of two 2 HP modules that allow you to connect a chain of controllers to your DROID master through a standard 3.5 mm stereo cable (sometimes also called aux-cable).

The usual idea is that you put all your DROID controllers into a skiff case and mount your DROID master, X7 and G8 into another case, together with all your fancy Eurorack sound modules.

R2C is module 2 of a pair of two 2 HP modules that allow you to connect a chain of controllers to your DROID master through a standard 3.5 mm stereo cable (sometimes also called aux-cable).

The usual idea is that you put all your DROID controllers into a skiff case and mount your DROID master, X7 and G8 into another case, together with all your fancy Eurorack sound modules.

While you could do this with the typical 6-pin ribbon connector (e.g. the 80 cm version that we offer), using the R2M/R2C combination has some serious advantages:

The connection cable can be almost arbitrary long (20 m have been tested and works perfectly).

Since the connection is done on the front of the modules, you can quickly disconnect your skiff for the purpose of travelling to a gig.

You can use a standard 3.5 mm stereo TRS cable for the connection.

These modules are not just passive connectors but contain special driver ICs that transform the electronic voltage levels, which run in the 6-pin ribbon, to something more stable and reliable that is fit for longer distances in a more hostile environment.

The controllers do not receive their power from the master but from the R2C module, which has a power connector and a voltage regulator for that purpose. Each chain of the R2C module provides the same power to its controller chain as the master does (it contains the identical voltage regulator). That means that you can connect up to 32 controllers (!) to one R2C.

Another nice thing: The R2M/R2C combination allows for two of these master / controller connections in parallel. That means that you can have two masters being attached to their individual controller chains. That does not mean, that each of the masters can access each of the controllers at the same time, however. Both master / controller connections work completely separately.

Package contents:
* one R2M module
* one R2C module
* one Eurorack power cable for the R2C
* two 6-pin ribbon cables for connecting the R2M to two masters
* two 3.5 mm stereo TRS cables, approx.. 1.2 m
* 4 red M3 screws for mounting the two modules

For this item, Frequency Central offer a CHIPSET which contains the following:

3 x LM13700

For all other components required, please see the build document.

Features:

4 x input channels, each featuring LEVEL, HIGH, LOW, FX send, PAN, MUTE and CV control of level.
FX send and stereo return + FX phase jumper
Left and Right Eurorack level inputs (2 x 3.5mm sockets)
Left and Right line level outputs (2 x 6.35mm sockets)
Scribble strips!

Strips is also expandable! You can add a second strips, connected to the first via a 16 pin to 16 pin cable. The cable powers the second Strips and gives you 8 channels to play with. The second Strips accesses the first Strips FX bus. When using in expanded configuration, the FX send/return and main outputs for the second Strips are not available. Here's how!

FX phase jumper - because not all FX that you might use in the FX loop are in phase with respect to their input/output. The phase jumper allows you to compensate for this and avoid weird phase cancellations.

Notes: This is an envelope follower based on a classic module from the seventies but with some improvements to suit modern needs.

The IN signal is bifurcated to the envelope follower circuit and also to a THRU output, so the original signal is also available for external processing.

The envelope follower has three controls, a switch to select response time (fast, medium, slow), a pot to adjust GATE threshold and a pot to adjust the envelope CV level.

This little module will help you shape the timbre and/or the level envelopes of your sounds. From dynamic envelope filtering to compressor like side chaining there are lots of possibilities to mangle your audio.

- 35mm depth behind front panel including the power connector
- standard 10 pin euro power +12V / -12V
- power consumption +12V 18mA , -12V 16mA

Notes: As the name suggests this module can produce sub frequencies of -1 and -2 octaves relative to the square wave signal provided at the input jack.

But this is not just a simple SUB generator. It also has a little mixer that will let you add different levels of -1 and -2 octave signals to the original square wave. You can select the -2 octave signal to be a square wave or a pulse wave.

The module has individual outputs for the mixed signal, the -1 octave and the -2 octave.

This little modules can produce enough timbral variation to make you bass sound exciting.

Notes: Module A-105-2V is a voltage controlled low pass filter with 24dB/octave slope.

It is the successor of the A-105 which had to be discontinued because the obsolete SSM2044 filter circuit. The A-105-2 is based on the SSI2144 which is in turn the successor circuit of the SSM2044. The features of both modules are nearly the same. The main difference is the clearly reduced front panel width of the A-105-2 (4HP instead of 8HP) and the associated changes of the controls and sockets positions. In addition the A-105-2 is equipped with 2 audio inputs.

The module has these controls and in/outputs available:

Control Frequ: manual frequency control
Control FCV2: attenuator for the frequency control voltage applied to socket FCV2
Control Q: manual resonance control
Control QCV: attenuator for the resonance control voltage applied to socket QCV
Control Input 1 Level: attenuator for the audio input signal applied to socket Input 1
Socket Input 1: audio input 1 (with attenuator)
Socket Input 2: audio input 2 (without attenuator)
Socket FCV1: frequency control voltage 1 (without attenuator, about 1V/oct scale)
Socket FCV2: frequency control voltage 2 (with attenuator)
Socket QCV: resonance control voltage (with attenuator)
Socket Out: audio output
Technical notes:

Frequency range: about 15Hz ... 15 kHz
Resonance up to self oscillation
Max. input voltage at Input 2 without clipping/distortion: about 15Vpp
Max. output voltage without clipping/distortion: about 15Vpp
The signals of both inputs are mixed before they are processed by the filter. This saves an external mixer for small setups.
Depth: 45 mm

Notes: Module A-130-2v is composed of two identical voltage controlled amplifiers (VCA). Each VCA has a manual gain control (also named Initial Gain) and a control voltage input with attenuator. The character of the control scale can be switched to linear or exponential. All inputs and outputs are DC coupled. Consequently the VCAs can be used to process both audio and control voltages (e.g. for voltage control of the level of LFO or envelope signals). The signal input has no attenuator available but is capable to process up to 16Vpp signals (i.e. -8V...+8V) without distortion. For the processing of higher levels an external attenuator (e.g. A-183-1) is recommended.

The amplification range is 0...1. Even with a higher external control voltage the amplification remains at 1 (kind of "amplification clipping" at 1).

Controls (for each of both units):

Gain: manual gain control (Initial Gain) in the range 0...1
CV: attenuator for the CV input
lin/exp: switches the VCA characteristic to linear or exponential, in center position the VCA is off (mute function)
Inputs and outputs (for each of both units):

CV: control voltage input, min. +5V required for max. amplification (1) with CV control fully CW and Gain fully CCW
In: signal input, max. 16Vpp (+8V...-8V) without distortion
Out: signal output

A-130-2v is the slim version of module A-132-3 and offers essentially the same features. 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-132-3. The module is primarily planned for applications where only limited space is available.

Power consumption: 30mA at +12V and 30mA at -12V

Depth: 50mm

Notes: MIX7 is a seven channel analogue summing mixer module for Eurorack. It is designed for summing any of the different types of signals you'll find in a modular system: Audio, CV, Triggers, or Gate.

MIX7 gives ability to sweeten your mix with more headroom using the power of low noise analog summing. A compact 3HP Eurorack utility module, MIX7 is an attractive mixing addition to any rig, especially with the ability to also combine rhythms, note patterns or CV automations from different control sources. The main output of one section can be connected to the input of another MIX7 to create larger mixing groups and complex signal routes inside your modular.

The MIX7 summing mixing circuit is built with low-noise operational amplifiers, giving it an excellent sound quality for mixing audio, the beautiful texture of classic analog mixing with plenty of headroom to handle hot modular signals, and the versatility to sum non-audio signals in your system to open up new creative possibilities.

Each input is labeled with a number of dots, 1-7, yellow for input and green for output. The module matches Tiptop's system look with clean white faceplate styling.

At the back of the module is a user-configurable jumper allowing users to configure the MIX7 for either unity gain (OUT = IN) or give increased headroom (OUT = 0.4IN) for use with hot audio signals, which makes it a great pairing for Tiptop Audio percussive modules. A peak indicator light on the front panel warns the user of even the slightest audio clipping in the mix, helping to keep all the incoming sound sources at their full original quality.

Notes: The Serge GTO is a newly designed, complex multi-functional module which can be patch programmed to provide various slew and sample functions both for audio and CV signals, but also act as a (dual) oscillator or filter or bitcrusher or ... It is one of the essential Serge modules. The GTO is an offspring of the famous Serge SSG.

The Smooth section will place a positive and negative slew on input voltage transitions for lag effects, voltage controlled portamento and for low frequency filter applications. In Cycle-mode (cycle jack patched to the input), the Smooth side “will oscillate yielding a voltage controlled triangle wave LFO. A high level into the HOLD input will enable the Smooth Function to be used as a track-and-hold circuit with voltage controlled slew rate.

The Stepped function can be used as a sample-and-hold with voltage controlled slew rate limiting. In Cycle mode, a pulse applied to the Sample input will generate complex staircase waveforms for control voltage applications and for use as audio signals.

Each side has a temperature-compensated 1V/Oct input for use as an oscillator with a frequency range of up to 20kHz (left) and 8kHz (right). Each side tracks over 5 or 6 octaves.

The Coupler is an internal comparator which compares the output levels of the Smooth and the Stepped Generators. This output is useful for generating complex control voltages or random voltages.

Notes: The Haible VC Resonator is an evolution of Jurgen Haible's Resonator which was inspired by the Polymoog Resonator. As Jurgen stated: The Polymoog, an early polyphonic synthesizer, featured a 3-band "Resonator" section that allows Formant-Filtering in addition to its dynamic Filters. Such a Resonator is a very useful feature for analogue synthesizers. Each of the three (now overlapping) filter bands has a control for frequency, signal gain, and emphasis (resonance). The VC Resonator now not only adds VC control for each band, but also extends the ranges whithin which each frequency band can be set - adjacent bands can now overlap or even cross over, for instance the LOW and MED bands can now be set (or moved!) so that the LOW center frequency is higher than the MED frequency.

Jurgen's original Resonator (like the Polymoog) had a switch to select one of 3 basic modes, i.e. only one mode could be used at a time. The Haible VC Resonator now provids the same 3 modes as separate outputs so they can be used simultanously, e.g. for further processing like crossfading.

Some details of the Haible VC Resonator:

Evolution of Jurgen Haible's design
Added Voltage Control for Filter bands
Extended range of each band (overlapping)
Three separate outputs
Burr-Brown op-amps and high-end VCAs
Eurorack (3U) format, 18 hp

Power: appr. 60mA @ +12V and 60mA @ -12V

Notes: The Morphor Plectrum - Analogue BBD Pluck is the successor of Morphor's successful module. Now only 8 HP instead of 10 HP with additional CV-able feedback!

Plectrum is a high quality, fully analogue Eurorack module that can produce plucked string-like sounds. It is a compact all-in-one solution for generating amazing bass, acoustic guitar, percussion and other amazing sounds.

The module is based on the Karplus-Strong principle with a true analog audio path built with an authentic bucket brigade delay (BBD) circuit which is recognizable by its specific timbre. By using carefully chosen high quality components, this module has a rich, warm analogue sound.

Now being only 8 HP in width, you won't need a lot of space to get going and start creating some incredible sounds. If you're looking to fully sculpt the string-like sound, you can extend the internal Karplus-Strong loop by breaking out the signal and adding external modules like filters and/or FX modules to it.

Notes: Building on the familiar dual VCO core arrangement of Carrier and Modulator, Mindphaser is a complex oscillator which departs from this bit of ancestral DNA with a modern toolkit focused on searing, phase-modulated leads, percussive basslines and other-worldly effects!

A diverse palette of intermodulation and harmonic experimentation is offered through the Modulation Bus, its unique Waveshaper and the dedicated Thru-zero Phase Modulation Bus. An intuitive interface provides colour-coded visual feedback and responsive indication while performing in dimly-lit environments.

Two precision analogue oscillator cores

Precision, wide-range V/oct ramp cores, each ranging from deep subsonic to supersonic frequencies (ramp cores, and not triangular, deliver the ideal waveforms for analogue phase accumulation in the TZ-PM Bus)
Each core generates fundamental waveshapes which interact and mangle one-another through the complex Modulation Bus and TZ-PM bus
Simultaneous waveform outputs for each base shape
Dedicated button to toggle between RAMP or SAW for each core, inverting the phase of the ramp output
V/oct, linear FM and exponential FM inputs which are all independent of the TZ-PM functionality. The Carrier's FM occurs inside the core itself, separate from the TZ-PM bus.
DC-coupled linear FM

Carrier

The heartbeat of Mindphaser, focused on audio-rate generation. Drives the WAVESHAPER and TZ-PM bus. This core's frequency range spans the audible spectrum.

- An external hard SYNC IN forcibly resets the core, useful for punchy sequences, percussive basslines and drum synthesis -- or to sync to another VCO.

- Coarse and fine controls conveniently span the audible spectrum. Ranges further with external CV.

Modulator

An extremely wide range oscillator, spanning from deep LFO frequencies all the way up to supersonic sound! Four base waveforms and diverse internal routing options form a versatile palette of modulations for the CARRIER to feed on.

- Activating hard SYNC on the Modulator locks its core to the Carrier's heartbeat. The effect can be dramatic. Try this while phase modulating!

- Octave RANGE switch lets you quickly flick up and down between octaves. All the way beyond audio-rate and LFO speed octaves. Perfect for experimenting with different PM sidebands and taming the wide frequency range of the Modulator.

- Manual PW (Pulse Width) control and dedicated CV input for PWM.

Waveshaper

This isn't a classic waveshaper! Developed anew from the ground up, this waveshaper is focused on deep harmonic experimentation and audio obliteration. Each waveshaper parameter is capable of being "turned up to 11".

FOLD up to 5 octaves above the fundamental Carrier frequency. A ceiling forms at maximum, imparting additional harmonics.

FEEDBACK the waveshaped and phase-modulated audio through a signal path internal to the waveshaper.

AMPLITUDE modulation spans thru-zero, allowing for full-range ring modulation effects with bipolar CV or audio signals.

CLIP the final stage of amplitude with the switch to introduce a last stage of harmonics before the complex signal exits through the final OUT.

Switchable inverting attenuators on each CV input, for quickly inverting the behaviour of your modulation. The indicator illuminates red to tell you the attenuator has been inverted.

Two distinct waveshaping modes

A press of the shape switch toggles Mindphaser between RAMPOID (green) and TRIANGULAR (yellow) waveshaping modes.

These modes have a remarkable effect on the behaviour of wavefolding and overall character of the final complex OUT, in addition to TZ-PM Bus character.

RAMPOID mode folds more asymmetrically, with raucous, buzzing harmonic artefacts as you sweep and introduce TZ-PM

TRIANGULAR mode folds more symmetric, splitting the complex sine wave at its peak centre of the waveform. TZ-PM character is less raucous, and more smooth.

TZ-PM Bus

Thru-zero phase modulation in the ANALOGUE realm! Unlike its digital counterpart, analogue TZ-PM has its own character we've come to expect from analogue circuitry!

A dedicated, voltage-controlled phase modulation bus completely separate from the Mod Bus
Modulator's SINE wave normalled to the PM SOURCE input
SOURCE input allows you to modulate phase with any signal you patch in
Dedicated voltage-controlled INDEX (amount)
Manual phase lets you zero in (or not!) on the base phase before introducing modulation
Independent of the Linear FM circuitry in the Carrier core

Mod Bus

The internal modulation powerhouse, normally fed by the Modulator core, but external signals are patchable as well.

Select from the PULSE, RAMP/SAW or SINE output of the MODULATOR, or inject your own SOURCE to the bus.

Voltage-controlled INDEX behaves like a macro control when combined with various amounts and polarities dialled in at each CV destination.

Internal sends include the Carrier's classic Linear FM, Amplitude, Feedback and TZ-PM Index, with variable amounts and polarities!

Modulator waveforms internally feeding the Mod Bus behave unipolarly, for predictable modulation of every Mod Bus destination, without external patching. By patching in one of the Modulator's bipolar waveform outputs manually (or any external signal), you can override this behaviour.

Eurorack is a synthesist's toy chest. Stompboxes are a guitarist's toy chest. Each industry offers a seemingly infinite variety of products that enable musicians to build systems unique to their needs and to create a signature sound. Each is also somewhat addictive. Rare is the musician who doesn't eventually need a larger toy chest to house the accumulated toys.

Fortunately for the budget-conscious musician, Eurorack modules and stompboxes have always existed in separate worlds - someone whose Eurorack system consumes an entire wall in their home is usually not the same person whose pedalboard now requires a dedicated roadie just to transport it to the gig.

Intellijel's Stomp removes the barrier between Eurorack and stompbox. It provides the modular synthesist with a portal to stompbox nirvana, and the guitarist with a wormhole to the sonic manipulations of Eurorack modules.

Stomp enables the modular synthesist to interact with the impressive assortment of delays, choruses, flangers, phasers, fuzz boxes, tremolos, wah-wahs, amp simulators, compressors, and pitch shifter pedals available to guitarists. If your effects pedal is adorned with an expression pedal input, Stomp supports that too, and even features a built-in LFO to modulate your pedal's expression input. Need something crazier? No problem. Simply patch any modulation source from your modular system into the expression control jack to override the built-in LFO.

Conversely, guitarists can plug their guitar directly into Stomp's RETURN jack, giving them access to the myriad filters, ring mods, wavefolders and - most importantly - the near-infinite CV modulation delights inherent in Eurorack.

Features:

Robust Neutrik 1/4" TS connectors for the SEND/RETURN and TRS for the Expression interface
Signals arriving at Stomp's RETURN jack pass through a Class A triode emulator, allowing for some tube-like overdrive at high gain setting.
Stomp is more than just a simple level shifter - it's also an impedance converter, which provides proper drive and loading for any FX pedals or instruments you connect.
Separate gain controls on both the SEND and RETURN. This enables you to adjust the level of any audio being sent to the FX pedals as well as any audio coming back into the modular. Not only does this allow you to optimize the signal-to-noise ratio, but by significantly boosting the RETURN level, you can achieve some pleasingly overdriven tones.
Supports both Instrument and Line levels via a front panel switch.
Use Stomp's RETURN circuit as a "direct box" for connecting any instrument.
The high input impedance of the RETURN circuit allows it to be used as a piezo pickup preamp for acoustic instruments.
Use Stomp in the studio as an active "re-amping" device to play pre-recorded tracks back through guitar amplifiers or pedals.
All inputs are protected for minimum RF interference.
Return signal can be phase inverted for use with those pedals or effects types that invert phase.
Low MIX output impedance for driving long cables, lower noise, and minimum interference from outside sources.
The Expression Pedal Output converts analogue CV sources (or the internal LFO) into an output compatible with most stompbox Expression inputs.

A-138s is a simple but useful 4-in-2 mixing tool. It has four inputs available. Each input is equipped with an attenuator (Level) and a panning control that is used to distribute the signal to the left and right output. Beyond stereo mixing it is equally suited to create variable parallel routings. For example: Any of the four inputs may be routed in variable intensity to feed two filters.

You may regard the A-138s as a smaller version of the A-138m Matrix Mixer.

Inputs and outputs are DC coupled, i.e. the module can be used for the mixing of control signals too.

Notes: Great value from this versatile percussion module, built around a noise generator and four linked envelope generators, each with its own VCA. Generate hi-hats, envelopes, shape drums or create modulation sequences.

Supplier's Notes:
Ricochet is a compact, fully analogue module featuring four interconnected decay envelopes, each with its own VCA and an integrated noise generator.

The module's design is inspired by the way skipping stones bounce on the water, creating a versatile tool for crafting percussive sounds.

The exponential envelopes are specifically designed to generate dynamic percussive tones. The unique linking function connects the end of one envelope's decay to the trigger of the next, enabling the subsequent envelope to activate once the previous one ends. This innovative feature allows you to create ratcheted envelope.

A front-panel trimmer lets you adjust the threshold for triggering subsequent envelopes, while a rear header enables connecting two Ricochet modules together, or linking the last envelope to the first. This feature transform the Ricochet to a weird sequencer where the steps length depend of the decay times.

Since Ricochet is fully analogic, trig inputs are velocity-sensitive, responding to a standard gates but also allowing attenuation to modify the envelope's velocity (you can play with the dynamic of your sound by attenuating the trigg input. Ricochet is also perfect to play with drum pads).

Each VCA features a gain control that can be pushed to achieve subtle saturation.

All envelopes and VCAs have separate outputs, but there are also mixed audio and envelope outputs. When an individual output is connected, it is removed from the mix. The decay modulation inputs are normalized between each other.

Last but not least, an analogue noise generator is normalised to the first input, so you can use ricochet on it's own to create hi hat kind of sounds

Main features:

- Fully analogue design so everything is responsive to the amplitude
- Unique linked envelopes feature
- Compact 4 envelopes 4 VCAs module
- Linkable to a second ricochet or looping back the last envelope to the first one

Some applications:

- Envelope generator
- Drum shaper
- Hi-hat
- Clap envelope shaper( with short ratcheted envelopes)
- Envelope sequencer
- Trigg delay
- Burst generator

Technical details:

- Fully Analogue design
- 14hp
- Skiff friendly
- Reverse power protection

Fortunately for the budget-conscious musician, Eurorack modules and stompboxes have always existed in separate worlds - someone whose Eurorack system consumes an entire wall in their home is usually not the same person whose pedalboard now requires a dedicated roadie just to transport it to the gig.

Intellijel's Stomp removes the barrier between Eurorack and stompbox. It provides the modular synthesist with a portal to stompbox nirvana, and the guitarist with a wormhole to the sonic manipulations of Eurorack modules.

Stomp enables the modular synthesist to interact with the impressive assortment of delays, choruses, flangers, phasers, fuzz boxes, tremolos, wah-wahs, amp simulators, compressors, and pitch shifter pedals available to guitarists. If your effects pedal is adorned with an expression pedal input, Stomp supports that too, and even features a built-in LFO to modulate your pedal's expression input. Need something crazier? No problem. Simply patch any modulation source from your modular system into the expression control jack to override the built-in LFO.

Conversely, guitarists can plug their guitar directly into Stomp's RETURN jack, giving them access to the myriad filters, ring mods, wavefolders and - most importantly - the near-infinite CV modulation delights inherent in Eurorack.

Features:

Robust Neutrik 1/4" TS connectors for the SEND/RETURN and TRS for the Expression interface
Signals arriving at Stomp's RETURN jack pass through a Class A triode emulator, allowing for some tube-like overdrive at high gain setting.
Stomp is more than just a simple level shifter - it's also an impedance converter, which provides proper drive and loading for any FX pedals or instruments you connect.
Separate gain controls on both the SEND and RETURN. This enables you to adjust the level of any audio being sent to the FX pedals as well as any audio coming back into the modular. Not only does this allow you to optimize the signal-to-noise ratio, but by significantly boosting the RETURN level, you can achieve some pleasingly overdriven tones.
Supports both Instrument and Line levels via a front panel switch.
Use Stomp's RETURN circuit as a "direct box" for connecting any instrument.
The high input impedance of the RETURN circuit allows it to be used as a piezo pickup preamp for acoustic instruments.
Use Stomp in the studio as an active "re-amping" device to play pre-recorded tracks back through guitar amplifiers or pedals.
All inputs are protected for minimum RF interference.
Return signal can be phase inverted for use with those pedals or effects types that invert phase.
Low MIX output impedance for driving long cables, lower noise, and minimum interference from outside sources.
The Expression Pedal Output converts analogue CV sources (or the internal LFO) into an output compatible with most stompbox Expression inputs.

Notes: The C-1U module is a one-channel module for recording and playing back movements of controller. Those can be recorded with channel's knob. The movements will be output as control voltage. The record time amounts to one minute maximal.

The track can be played once only (one shot) or in loop. The speed of the play back or the output offset is controllable with the pot. There are an additional CV input for CV recordings and a reset input.

The track data remains permanently stored when a 3V battery is used to buffer the RAM. When the module is switched on, the recorded data is available again. The module can be operated unipolar or bipolar (set by jumper on the back).

Note: The C-1U KnobRekorder uses a standard 3v lithium backup battery , type CR2032. The battery is needed to keep recordings and settings stored when the Eurorack case is turned off.

Module is a 1U tile.

Notes: A fresh twist on a simple 303-style acid synth, featuring a triangle/sawtooth/square wave VCO, multi-mode resonant filter, simple AD envelope and a VCA which can be overdriven. Excellent value.

Supplier's Notes:
ADDAC started this module with the idea of developing a complex drum source however, somewhere along the process, it was clear how much better it performed as a synth voice and this lucky accident was embraced.

It features a VCO with a [FREQUENCY] and [FINE TUNE] knob plus a dedicated CV Input and Attenuator knob (tunable over 4 octaves).

The VCO waveform output is achieved by selecting either a Triangle or Saw through a switch. the selected waveform can then be mixed/balanced against the square wave. The resulting mix is then sent to the Filter.

The Filter features a [CUTOFF] and [RESO] resonance knob plus a Cutoff CV Input and Attenuverter knob.

A 3 position switch is used to select the filter type: Highpass, Bandpass or Lowpass.

The resulting output is then sent to the VCA.

The VCA features an Input with [INPUT GAIN] knob which at maximum can amplify the incoming signal by a factor of 2.

This is a very important control, it accepts any signal Trigger, Gate or CV. Whatever input is plugged in the signal is then fed through an AD with a very short attack and controllable decay through the [VCA DECAY] knob plus the CV Input and Attenuverter knob. The resulting slewed signal is then used to control the VCA gain.

This signal is also sent to the CV OUTPUT as well as the LED monitor.

The Accent input adds to the Input signal creating a different amplitude output.


The CV OUTPUT is normalled to the Frequency and Cutoff inputs.

The [INPUT GAIN] knob

Usually Attack/Decay envelopes have a maximum voltage of +5v, no matter if the input gate is +5v or above the AD will clip at +5v. In this case, this clipping method was not used, and instead ADDAC allowed the incoming voltage to determine the maximum AD voltage, meaning that if a +5v gate is present then the AD maximum voltage will be +5v but if a gate of +10v is sent then the AD maximum voltage will be +10v.
This also means that with higher input voltages the decay, although falling at the same speed, will be longer than with lower voltages as it has a longer range to go back to 0v.

As previously mentioned, The [INPUT GAIN] knob can amplify the incoming input by a factor of 2, allowing to use a standard +5v gate or envelope and being able to make the resultant AD go up to +10v.

The AD signal is responsible for opening the VCA. Up to +5v the VCA will open to unity gain above this value the VCA will start to amplify and eventually saturate and distort. This saturation will add harmonics to the signal which will change its gentle timbrical nature to a more unique and peculiar timbre that will make the module shine in Acid contexts.

Adding high levels of Resonance or even filter self oscillation in combination with high VCA saturation will create even more harmonics that ADDAC highly encourage the user to explore.
