Notes: The ‘Pip Slope’ (rev II) is a compact envelope and function generator. It supports both Attack/Decay and Attack/Sustain/Decay type envelopes with both direct and voltage control of Attack and Decay times. Envelope shapes can be morphed between exponential, linear and logarithmic type slopes. Envelopes can be made to loop, repeating infinitely or decreasing with time or amplitude for echo and bouncing ball type effects. An ‘End of Cycle’ trigger output further extends the envelopes functionality for both clocking and burst or fill type effects.

The improved Pip Slope adds a number of new features and updates over the original Pip whilst keeping the same size. Improvements include increased output resolution, finer control of fast envelopes, a new morphing shape control, switchable 5v or 8v maximum envelope level, additional loop modes and an additional trigger output.

Features:
Compact envelope and function generator in 4HP.
Trigger and gate inputs.
Voltage and direct control of attack and release times.
Snappy or super long envelope times – ranging approx 1ms to 7 minutes per stage.
Optional self looping ability with 3 different loop modes: Decreasing amplitude, decreasing time, and regular loop.
Shape control that morphs the envelope shape from logarithmic to linear to exponential curves.
End of Slope trigger output that fires a trigger at the end the envelope or loop cycle.
Selectable 5v or 8v max envelope level output.
Reverse polarity protection.
Skiff friendly.
Designed and Made in the UK.

Notes: Module A-145-4 is a simple quad LFO (Low Frequency Oscillator). Not a very "exciting" module, just a bread-and-butter device and a simple demon for work. Virtually in every modular system several LFOs are required for modulation purposes. The module contains four simple LFOs with the waveforms triangle and rectangle. A dual colour LED (red = positive / yellow = negative output voltage) indicates the triangle output of each LFO. The frequency range can be chosen for each LFO individually by means of a jumper between about 50 Hz ... 0.04 Hz (about 20 seconds, jumper removed) and about 2Hz ... 0.002 (about 8 minutes, jumper installed).

The module can be treated as a slimmed version of the quad LFO A-143-3 as it has similar features available. 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 less than one third of the A-143-3. The module is primarily planned for applications where only limited space is available. The functional difference compared to the A-143-3 are the missing sawtooth outputs and frequency range switches.

Notes: Full-featured triangle core VCO/LFO

The Dixie II+ is a larger variant of the classic Dixie II. Using the same great triangle core oscillator, it adds a number of features to make it even more versatile with only a modest increase in size. The Dixie II+ makes a great primary oscillator for a modular system, or a great companion the Rubicon.

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: 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: 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: 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: 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: ***Now featuring Assimil8or Software Version 2.0! Available to download here: http://www.rossum-electro.com/products/assimil8or/

The ASSIMIL8OR is a CV/Gate-controllable sampler with eight independent channels. Each channel is not only its own voice, but also has a separate audio output and a gate/trigger and three CV inputs. Given ever get two sample inputs and main outputs. Thus, Stereo Sampling and playback is possible. Mixed operation of stereo or mono is possible and is limited only by the maximum number of eight channels or parts.

The ASSIMIL8OR works with high-quality 24-bit AD and DA converters. Internally, however, sample and bit rate for lo-fi sound can be lowered, the latter is even CV-controllable. The samples can also be otherwise manipulated in many ways. Thus, the phase of a sample via CV or a different sample can be modulated. Likewise, the loop points can be controlled and the sample can be traversed with CV control (scrubbing), whereby wavetable similar effects could be achieved. The following parameters can be addressed via the gate / trigger and CV inputs:

- Pitch
- Level
- Bit Depth
- Phase Modulation
- Pan
- Scrub
- Sample Start
- Sample Length
- Loop Start
- Loop Length
- Release Decay

Samples and presets are stored on an SD card, which is easily accessible plugged into the module front.

Notes: Javelin is a module that is basically an ADSR envelope with integrated VCA. However, it has several features that make the module an expressive sound shaping tool.

Three level ranges determine the total amplitude of the envelope, additionally three different time ranges are integrated, which can be switched between.

The accent behaviour is also unique. If several gates are applied to the Accent input at the same time, the envelope rises slightly with each gate.

Features:

Attack-decay-sustain-release envelope
Integrated VCA
Unique accent behaviour for expressive sequences
Reset input
CV control over attack and release
Looping mode for LFO-like modulations
Mode switch for gate and trigger behaviour

Notes: The legendary Buchla 259 complex oscillator gets the officially licensed Eurorack treatment from TipTop Audio. One of the most versatile and characterful VCOs ever made, with endless cross-modulation options and wave shaping features. Iconic.

Supplier's Notes:
The 259t is the largest and most complex analogue oscillator from Don Buchla's legendary 200 modular synthesiser. The 259 originated the concept of the "Complex Oscillator" in the 1970s and has been reissued by Buchla and Tiptop Audio in Eurorack format. The module consists of two oscillators, called the Modulator and Principal, with a middle section that provides voltage control over the internal modulation paths between the two oscillators, resulting in highly complex timbres. Additionally, the principal oscillator passes through multiple unique voltage-controlled waveshapers and crossfaders for further signal processing. The module's pitch can be controlled with 1V/OCT or via its internal auto-tuner and ART control to create precisely pitched notes.

Notes: A warm and deep sound source you can rely on

Notes: A true legend of modular synthesis, Make Noise's Maths is arguably the definitive Eurorack function generator. Based on analogue computing circuits, Maths draws on Buchla-style techniques to offer countless ways of generating and processing modulation signals.

Supplier's Notes:
The MATHS music synthesizer module is an analogue computer designed for musical purposes. Amongst other things, it will allow you to:

Features

Generate a variety of linear, logarithmic, or exponential triggered or continuous functions

Integrate an incoming signal

With no signal applied, generate a variety of linear, logarithmic, or exponential functions

Add, subtract and OR up to 4 signals

Generate digital information (Gate / Clock) from analog signals

Delay digital (Gate / Clock) information

If the above list reads like science rather than music, here is the translation:

Voltage Controlled Envelope or LFO as slow as 25 minutes and as fast as 1khz

Apply Lag, Slew or Portamento to control voltages

Change the depth of modulation and modulate backwards!

Combine up to 4 control signals to create more complex modulations

Notes: Delta-V is a fully analogue dual-channel function generator, featuring a dedicated VCA and LFO cycle switch for each channel. It packs a great deal of functionality in only 10HP, and will surely find use in almost every patch.

Generate envelopes, slew gates and signals, or run LFOs with precise control over attack and decay times. Using the SHAPE knob, Delta-v can create a wide range of envelopes, from very snappy exponential curves for percussion to logarithmic thumps for bass lines.

If VCA's input is unpatched, the module outputs a regular voltage envelope. When an audio signal is patched into the VCA input, the output signal becomes the audio signal amplified by the envelope.

Sending other envelopes or an LFO to VCA input lets you modulate those modulators, quickly creating complex control voltages that go beyond the usual attack-decay envelope.

Combine this with the SUM output, which sums the two channels, and the attenuverters, which can quickly attenuate or invert the signal, and you have a whole array of signal processing capabilities.

The TRIGGER input fires a Attack-Decay envelope, while the SLEW input will affect the rate of change of the signal.

The trigger for channel 1 and 2 can be linked together, so you can fire two envelopes with one patch cable.

Each channel has an End of Cycle output, (EOC) this outputs a short trigger at the end of each envelope cycle.

The output voltage ranges from -10 to +10 volts, set with handy output attenuverters.

The CYCLE switch starts looping the envelope, creating LFO's that go up to audio rate, and that can also be used as an interesting sound source.

There are many ways to utilise Delta-V.

Challenge yourself to explore new, unconventional territories!

Notes: A typically clever approach to modulation from Make Noise, the MultiMod takes a control signal and modifies it into eight related outputs, adjustable by phase and timing. Hugely versatile.

Supplier's Notes:
With MultiMod...from one control signal, we create many.

In a modular synthesiser, it is easy to create complex results via complex means - patching an elaborate network of independent control signals, for example. This can be very powerful but also cumbersome to set up, and potentially difficult to control in a meaningful way. MultiMod represents a new approach: it takes a single control signal and copies it 8 times, not unlike a simple mult, except that it allows you to modify those copies by weighted adjustment of their relative phase and speed. The result is modulation that is related to the source, but not identical at each destination.

Phase sets the spacing of the signal copies in time, weighted by channel, with each progressive channel getting more out of phase from the original signal and from each other. Spread allows for varispeeding the copies by different amounts, with each getting progressively faster or slower than the original Signal. Time determines the range of time captured at the input and therefore also the depth of modulation across copies of the input signal when Phase and Spread are manipulated. MultiMod also includes Tempo, Hold, and Reset features, and a variety of Read Shapes for temporal rearrangement of input signals.

When the input is not patched, MultiMod generates an LFO that is copied eight times and manipulated in the same ways.

MultiMod is built with the latest DSP hardware which offers eight high resolution outputs, with signal input and output ranges approaching the upper limits of the analogue eurorack modular system. All I/O is capable of a 20V range at +/-10V, greatly exceeding the typical 0-5V CV input ranges on typical digital modules.

Notes: The 'Quaid Megaslope' is a five stage function generator or modulator which operates in one of 3 modes; a multistage 'CZ' or 'Juno' style complex envelope, a super flexible LFO and a step sequencer with per step programmable slew or slides.

Each mode produces a varying output voltage moving from point to point across a set number of chained together stages. Each stage features a destination level, an overall rate or time to reach its destination level and a variable slope for the output path to take. As well as direct control, every stage feature voltage control of both level and rate. There are both unipolar and bipolar voltage outputs together with triggers emitted for the end of each stage and the end of a full cycle.

The Quaid Megaslope is designed to be fun, flexible and intuitive to use.

Notes: An updated version of the excellent Batumi quad LFO, version II introduces performance updates plus compatibility with the new Poti II expander. Original Poti I breakout functions are now included in the Batumi II.

Supplier's Notes:
Xaoc Devices presents Batumi II - a greatly improved and enhanced new iteration of the modern day classic that is/was the original Batumi, preserving its layout and form factor. The premise remains the same: four LFO's with individual outputs for sine, assign and rectangle waves. The channels can operate independently or they can be linked - phase shifted, divided or multiplied (new mode alert) with regard to the first channel. Multiple major and minor improvements have been implemented, e.g. when synced to an external clock source, each channel's frequency slider selects a clock division for that channel's outputs.

Xaoc Devices have managed to incorporate the features of the original expander into Batumi II (sync mode switching and assign waveform selection) without changing the size of the module which opened up new possibilities for the new optional expander. The Poti II expander for Batumi II adds multi destination inputs for sine wavefolding, assign output waveform selection or rectangle pulse modulation with the destination set for each channel independently. Poti II also features frequency input attenuation as well as sine and assign output attenuation. All adjustments may be performed separately for each individual channel or for all channels simultaneously.

The Batumi II software has been rewritten from scratch to ensure best performance. The hardware has also been updated to allow for V/oct tracking and stable operation up to audio rates (more powerful CPU, precise, wideband converters, antialiased waveforms).

-4 LFO's
- redesigned from scratch - both the hardware and software
- new waveforms for the assign output (including random)
- new frequency multiplication mode
- all features of the Poti expander incorporated into the main module
- very wide frequency range well into audio rate

- in the Phase/Divide/Mult modes the random waves at the ASGN output follow the values available in the master/A channel
- 10HP
- +90/-50mA

Notes: The Furthrrrr Generator has a main oscillator (carrier) with an extensive and fully voltage controllable wave multiplier and a modulation oscillator (modulator) that can cross-modulate the carrier. Each oscillator has hard and soft sync and also features an integrated tuner: if both LEDs are lit the VCO is at note A. Left LED is lit at note Ab and right LED at A#. Frequency potentiometers are ten-turn models and thus allow for easy tuning. Frequency range of the VCOs is 10Hz-10kHz (and much lower in modulator's LFO mode). Both VCOs feature 2 frequency CV inputs (1x with bipolar attenuator, 1x with 1V/octave), one FM input (jumper selectable between linear and exponential FM) as well as separate input for hard and soft sync. The voltage characteristic can be selected between 1V/octave and 1.2V/octave (Buchla norm).

The main oscillator (carrier) outputs the waveforms sine, saw, square and white noise. The two outputs marked with the magic eye are outputs of the "harmonic section" that generates very complex sounds by the wave multiplier and its parameters symmetry, order and Furthrrrr in the module's right-hand section. Symmetry lowers the level of even harmonics and amplifies the odd harmonics (this affects the pulse wave's width as well). Order adds saturation to the high order harmonics and resembles a low pass filter. Furthrrrr alters the level of harmonics set by the other parameters and produces very interesting, partly brute sounds with lots of harmonics by clipping and folding the wave. All three parameters can be voltage controlled. The carrier oscillator also has inputs for hard and soft sync, the sync-switch can synch directly to the modulator.

The modulation oscillator (modulator) has three wave forms with direct outputs: sine, saw and square. Using the internal modulation via the "mood section" the waveform is selected with a button; an additional staircase wave form is available here, but it can be overridden by inserting a signal into the external input socket. A switch activates the LFO mode.

The Mood section is responsible for the internal modulation of the carrier by the modulator. Switches determine the modulation destination(s) that can be activated simultaneously. These are the Furthrrrr parameter of the harmonic section, the amplitude and the frequency of the carrier oscillator. The "balanced" switch activates the ring modulation between both VCOs. intensity of modulation is controlled by the "mood index" potentiometer and the according CV input with bipolar attenuator.

Notes: A-111-4 contains four precision VCOs and has individual controls, inputs and outputs for each VCO available as well as a common control and output unit. After all the A-111-4 is very similar to four A-111-3 without LFO mode but built in output mixers for the three waveforms, and a master unit for all four VCOs.

Controls, inputs and outputs for each of the four VCOs:

- 1V/Octave CV input
- Octave switch (+1 / 0 / -1 octave)
- Tune control (range internally adjustable by jumpers: ~ 2 semitones / ~ 1 octave / ~ 4 octaves)
- Modulation CV input
- Modulation destination:
- Upper position: exponential frequency modulation (XM)lower position: linear frequency modulation (LM) or pulsewidth modulation of the rectangle (PM), selectable via internal jumper
- Frequency Modulation (FM) or Pulsewidth Modulation of the rectangle (PWM)
- Modulation intensity
- Triangle output
- Sawtooth output
- Rectangle output (about 50% without external PWM)
- Sync input (hard or soft sync internally selectable via jumper, CEM3340 hard sync type)
- Min. 10 octaves range (with appropriate external CV)
- CEM3340 based VCO (triangle core)
- Each VCO has it's own separate internal +/- power supply for each for best stability and the prevention of unwanted synchronisation of the VCOs

Controls, inputs and outputs of the master section:

- 1V/Octave CV input
- Octave switch (+1 / 0 / -1 octave)
- Tune control (range internally adjustable by jumpers: 2 semitones / 1 octave / 4 octaves)
- Frequency Modulation CV input (FM)
- FM intensity
- Triangle sum output
- Sawtooth sum output
- Rectangle sum output
- As soon as the single waveform output of a VCO is patched this waveform of the VCO in question is removed from the sum (this function can be turned off for each single output socket by means of solder bridges on the pc board, i.e. the sum contains then all signals independent of the patching of the single output)
- CV output (outputs the sum CV that is used to control all four VCOs)
- Bus CV (selectable via jumper)

Typical applications:

- Fat sounding monophonic VCO with the possibility to adjust any intervals
- Paraphonic patches in combination with the polyphonic CV interface A-190-5 (all four VCOs processed by one VCF/VCA)
- Full polyphonic patches in combination with the polyphonic CV interface A-190-5 and four complete VCF/VCA sections
- Complex VCO patches with up to four VCOs by means of the frequency modulation features (exponential an linear) and the sync functions

Notes: Pons Asinorum is a compact four-channel multimode envelope generator and LFO with voltage control. PA has three different envelope shapes, CV over cycle length, and a unique single encoder control scheme that makes adjusting multiple channels mid-performance easy. Channels can be set separately to envelope mode or to cycle in LFO mode, giving PA maximal flexibility in a minimal footprint.

Notes: Great value from this versatile six-channel function generator, suitable for LFOs, envelopes, slew limiting and much more. A versatile module at a good price.

Notes: Kermit is a 4-channel programmable supermodulator with morphing wavetable generator and internal modulation matrix. Four channels operate as LFOs, audio rate oscillators (with 1v/octave response on two channels), 1-shot envelopes, random voltage generators, or sample-and-holds, all responding to manual control, external control voltages, or synchronization to the module's master tap tempo clock. Designed for maximum patching power in small systems, Kermit carries an unmatched functionality-per-HP factor with an easily readable display that shows parameters in their real-world units.

The module has a 16-bit DAC to accurately render subtle changes of voltage at extremely low frequencies. The oscillator mode is best suited for bass frequencies, and the waveform "character" modes restrict the morph behavior or degenerate the audio to a minimum of 8 bits with limited horizontal resolution, like the Konami SCC chip used with the MSX computer. The tap tempo facility features an input jack and a manual button. The tempo is shown on the OLED display in BPM. The relevant units (hertz, seconds, volts, etc) or selected waveform of each channel are contextually shown on the display as the user programs the module.

List of operating modes per channel:

Code scan
1-shot envelope
Gated repeat envelope
Tap tempo envelope
Smooth random

Three parameters on each channel can be modulated: frequency, amplitude, or waveform. Both external CV input and internal cross modulation are programmable with hotkeys. For example: assign the output of Channel B to morph the waveform of Channel A by holding the Channel B button while turning the Channel A Waveform knob. All channels have manual control of frequency (coarse and fine), phase, wave bank, waveform morph, and amplitude. Channels A and B have full controls, C and D have single knob controls with deep parameters accessible by hotkey combinations. Still deeper functions are accessible through the Mark III menu system.

Kermit has a microSD card slot for loading custom waveforms, like its big brother Piston Honda. The SD card accepts one .WAV file in WaveEdit format (free software editor) containing 64 waveforms, also compatible with several other Eurorack modules. When loaded into Kermit, the waveforms are organized into 8 banks of 8 waveforms each. Each oscillator can select any of the 8 banks, and the 8 constituent waves can be smoothly morphed from one to another.

The Mark III morphing preset manager is in full effect on Kermit. The discrete preset mode quickly and reliably recalls all parameters in response to triggers or CV, accessing the true power of the module as detailed, carefully programmed settings are effortlessly loaded and changed. The morphing mode causes delightfully unexpected variations of the basis preset.

Insert a master clock signal and you're ready to go. Kermit is a reliable provider of endless rhythmically coherent modulation voltages and a reasonably competent "voice module" providing most common synthesis functions on each channel with an internal modulation matrix.

Notes: Tangrams

Push (or Pulse) the Envelope

Snappy, classically analogue envelopes with visually intuitive controls. Add a powerful, cv controllable cyclical gate generator, integrated VCA, and trigger buttons -then double it-now you've got Tangrams.

Tangrams, like the Dual ADSR before it, is a dual analogue core-envelope inspired by the Roland SH-101 / System 100m design with several enhancements. Taking further inspiration from trapezoidal function generators like the one on the EMS Synthi, Intellijel have added a voltage-controlled pulser circuit to link the triggering of two envelopes - allowing for delayed one-shots, cycling organic envelopes, and more. In addition, Intellijel added two VCAs for level control of each envelope, or alternatively, direct injection of the signal you'd like to envelope - freeing up your other VCAs.

The Pulser

The Pulser can be thought of as a way to set both a gate ON time (T1) and an OFF time (T2). In this way, you could configure a cycling ADSR that has a gate time that is different from the interval between gates. Alternatively, you can create a sequence where ADSR2 is triggered by a delayed amount of time after ADSR1 is triggered (either cyclically or in a single shot sequence). The panel switches for routing or disabling the pulse sources allow for even more complex combinations of control beyond these examples. This special combination of functions can yield a plethora of interesting and organic envelope and gate patterns to be created; cyclical and single shot.

Notes: *** Free software update available as a free download, along with updated documentation, at the Mob of Emus product page on the Rossum Electro-Music website***

A lot to unpack here. Six-channel multipurpose oscillator/noise source/modulation generator with quantisation, trigger generators and even more. Seriously powerful all-round digital goodness.

Supplier's Notes:
Mob of Emus is a powerful music and sound design tool that packs an enormous amount of creative power into an amazingly compact 16HP module.

Mob of Emus gives you six channels of oscillators, noise sources, cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes), sample and hold waveshapes, slow random modulators, triggers, rhythm patterns, and quantization (of both internal and external signals) in pretty much any combination (well, any combination of six channels, anyway).

In addition to being able to independently program the function of each individual channel, Mob of Emus' Hex Mode provides a macro control layer that allows you to control all of its channels simultaneously (while maintaining the relationships of each channel's independent programming).

What's more, Mob of Emus' "harmonic" control structure makes it extremely easy to combine its oscillators into rich additive timbres, to combine its LFOs into stacked harmonic low frequency modulation waves, and to create modulation sources and triggers with intricate polyrhythmic patterns.

With an external trigger input, six CV inputs that can operate in six different control modes, six independent outputs, and an assignable mix output, Mob of Emus can operate as the heart of an almost unlimited variety of patches. And its 8 real-time controls will give you immediate hands-on access to a channel's (or all six channels') key parameters, inviting (and rewarding) exploration and improvisation.

Mob of Emus features include:

Six channels that can function independently or can be further controlled by a Hex Mode macro layer that lets you control all six simultaneously. Channels can be:
Wide-range digital oscillators
Noise sources
Cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes)
Sample and hold waveshapes
Slow random modulators
Triggers
Rhythm patterns
Quantizers (of both internal and external(!) signals)
Six CV inputs that can function in six different control modes
Eight real-time controls for immediate access to key channel parameters
Six individual channel outputs and an assignable mix output
The ability to store and recall 12 user presets
And much more.

Mob of Emus is 16HP wide and 25mm deep.

Power requirements (max): 130mA +12V, 25mA -12V. Reverse polarity protected.

As of March 2021, there has been a been a small bug fix to the recent software update for Mob of Emus.

The update fixes a bug where holding the Channel Selector Buttons for a short time to select a single channel and deselect any others was not working correctly.

The update fixes a bug where some Hex Mode parameters were not ignored when Hex Mode was set to off.

The update introduces a feature allowing users to double-click and hold the Hex button to reset all Hex Mode parameters and set Hex Mode to on.

Notes: Module A-147-2 is the successor of the VCLFO A-147 but offers much more features than the predecessor. The module is made of these sub-units:

- VCLFO: voltage controlled low frequency oscillator
- VCA: voltage controlled amplifier, switchable to voltage controlled polarizer
- VC delay unit: voltage controlled linear attack envelope (only one parameter: attack) for delayed LFO operation in combination with the VCA (e.g. delayed vibrato/tremolo)

LFO: The voltage controlled LFO has the waveforms Triangle, Sine, Sawtooth and Rectangle available and features a Reset/Sync input. Triangle/Sine and Rectangle are displayed by means of dual-colour LEDs (probably red/green), Sawtooth has a unicolor LED available (probably blue). The output levels are about -4V...+4V for Triangle, Sine and Rectangle. The Sawtooth level is about 0...+8V.

The CV control can be switched to attenuator or polarizer ("CV Mode" switch). In polarizer mode the CV inputs affects the frequency in the reverse manner when the CV control is left from the centre position. In the centre position CV has no effect and right from the centre the control works like a normal attenuator. The frequency range (without external CV) is from about 0,005 Hz (i.e. about 3 minutes per period) to 200 Hz (with external CV max. frequency about 1kHz). In addition a ultra-low mode can be activated by means of an internal jumper. When the ultra-low jumper is set a fixed voltage is connected to the switching contact of the "LFO CV" socket. In polarizer mode of the CV control that way extremely low frequencies (up to one hour period and more) are possible. For this a jumper has to be installed on the pin header JP6. In the factory a dummy jumper is installed on the pin header JP7 "Dummy". JP7 has no function and is used only for "parking" of the jumper. Simply remove the jumper from JP7 and plug it on JP6. JP6 is located behind the CV control.

VCA: This is a linear VCA that can be switched to "normal" VCA (i.e. kind of a voltage controlled attenuator) or voltage controlled polarizer ("VCA Mode" switch). In the "normal" VCA mode amplification +1 is achieved with about +5V control voltage. In polarizer mode the amplification ranges from about -0.5 (i.e. inverted signal with about 50% level) with 0V CV to +0.5 (i.e. non-inverted signal with about 50% level) with +5V CV. With about +2.5V CV the signal is suppressed. Details about the functioning of a voltage controlled polarizer can be found in the description of the module A-133. In this mode the VCA can be treated also a DC coupled ring modulator (similar to A-114).

The VCA of the A-147-2 has three sockets available: "In" (signal input), "Out" (signal output) and "CV" (control voltage input).

The Triangle Output of the LFO is normalled to the VCA signal input by means of the switching contact of the "VCA In" socket. If another LFO waveform (or any other signal) should be processed by the VCA the corresponding signal has to be patched to the "VCA In" socket. The VCA can be used also independently from the LFO and the Delay CV. In this case the VCA sockets In, Out and CV have to be patched accordingly. The VCA can be used also as waveshaper for the LFO signals (e.g. by patching VCA In and VCA CV to different LFO signals, if necessary via attenuator A-183-1 or offset generator/attenuator A-183-2).

Attack/Delay: The third sub-unit of the module is a simple, voltage controlled envelope generator that has only the parameter "Delay" (or Attack) available. This unit generates a linear increasing voltage that starts from 0V after each Delay Reset until it reaches about +5V. Then the voltage remains at +5V until the next Delay Reset occurs. The inclination or gradient is controlled by the manual Delay control and the Delay control voltage ("Delay CV" input). The waveform is linear, the control scale is exponential. The output voltage is displayed by a green LED and available at the "Delay Out" socket.

The manual Delay control ranges - without external "Delay CV" - from about 5ms (fully CW) up to 2 minutes (fully CCW). By means of an external voltage applied to the "Delay CV" socket this range can be extended. A rising CV shortens the delay time (behaviour like a VCO)!

The Delay output voltage ranges from about 0V to +5V. The rising edge of the gate, clock or trigger signal applied to the "Delay Reset" sockets resets the Delay output voltage to 0 V.

"Delay Out" is normalled to the VCA CV input by means of the switching contact of the "VCA CV" socket and consequently controls the Triangle level provided that no other patch is made. A typical example is the usage of a Gate signal (e.g. from a USB/Midi-to-CV/Gate interface) as Delay Reset. That way a delayed vibrato or tremolo can be realized if the VCA output is patched to the frequency CV input of a VCO (or VCF), or the CV input of a VCA.

Notes: RACHAEL is an ideal companion to DECKARD'S VOICE or any other oscillator/sound source, bringing unique signal interaction and ring modulation capabilities to modular form. 100% analog, you'll find a wealth of facilities in this compact space, including full ring modulation, a dedicated VCO, a four-stage envelope with amount, and LFO.

Full-throated Ring Modulation
From tremolos to alien-invasion metallic screams, modulate any external source with RACHAEL's all-analog signal path, tunable to subtle, complex, and extreme sounds with the speed and depth controls. It's a perfect pairing for DECKARD'S VOICE or any input (via the signal input). In addition, there's both an internal reference oscillator and the ability to patch in your own external tone for even more complex and varied results.

Analog VCO
Set the oscillator to VCO mode, and RACHAEL is also a VCO with all the character of DECKARD'S DREAM and the classic CS synths that inspired it. That includes square, sine, and "csaw" waveforms -- the CSAW has the distinctive CS leading-edge pulse.

LFO
The oscillator is also configurable as an LFO, with standard sawtooth, square, and sine waves via switch. With a dedicated OSC output, you can use the LFO and ring modulation simultaneously, making RACHAEL both modulation source and creative processor.

A versatile, multipurpose envelope
RACHAEL's onboard envelope generator is more than just another ADSR. With the envelope generator amount control and switchable destinations, you can tune in an amount of the envelope to the modulation frequency, modulation depth, or both, for musical, creative sound shaping. In addition to the gate input, each stage of the envelope has dedicated CV control. And all of this comes with the distinctive vertical sliders beloved on DECKARD'S DREAM.

Notes: Dual tidal modulator with max, min & mix outs

FranKinksTides is a 18hp dual Tides (based on the Swirls pcb layout) with the max/min circuit from Kinks and some switches for sync, quadrature, pll and fm operation . It can be a double/complex oscillator, a dual function generator or any combination of oscillator, Lfo and Envelope generator with lots of cv control plus some interesting cross-modulation and sync features.

Some improvements in version 1.2:

-Mix output is now buffered, no signal bleeding on single outs.
-Mix pot controls also the balance of the signals sent to the max/min circuit.
-Uni/bi switch now also determines the signal sent to FM1.
-Clock/sync switch has now a center OFF position, no need of plugging a dummy cable in the Clock1 when using Sheeps firmware to avoid ultra fast sound bank changes.
small improvements for DIY:
-Bigger font size on the pcb.
-Parts renumbered for easy DIY.

Notes: A deep, comprehensive digital LFO offering 16 waveforms, sync, built-in VCA and more. All made even more powerful by the fact you can control every parameter via dedicated CV inputs.

Supplier's Notes:
Fully voltage controllable Eurorack format, externally syncable, 16 waveform low frequency oscillator with built-in VCA and sample & hold.

Powered by a socketed VCLFO10 IC from Electric Druid.

The core idea behind this module is all about control voltage. Hence all features are individually broken out to CV inputs, making the most use possible of the benefits of the digital wavetable oscillator. This means that the design is geared towards allowing hands-off control of all aspects and some concessions have been made to that effect.

Initial setup basically consists of connecting the power cable to the module and your bus. The cable has a slotted socket for correct orientation, but mind that the red stripe faces the white line on the edge of the pcb. The included screws are nylon in order to minimise rack-rash.

Tuning the module is possible by adjusting the small smd trim potentiometer on the back. It adjusts the offset voltage that affects the center point of the lfo oscillations. It should be close to its three o'clock position, but you can adjust it by turning the module on, reducing the output level to almost zero and turning the trim potentiometer until you find the point where the gate output led just barely turns off.

The LFO sync type is hard sync, meaning that it resets the current cycle to the beginning of the waveform. It does not control the duration of the cycles. This allows you to further shape the output to, say, three quarters of a sinewave by using external sync and adjusting the HZ knob so the duration of a cycle is just a little longer than the time between incoming sync pulses.

Color coded nuts indicate the type of jack, with gold representing Gate/Trigger input, black is +-5v CV inputs and red jacks are outputs.

The CV inputs are scaled down to +-2.5v and added/subtracted with the knob setting, meaning that to sweep the full range of the parameter with CV, the knob should be in center position. The inputs are clipped to the allowed range after mixing, so you can apply any eurorack voltage here.

The module's core processor is socketed, so using a simple PIC programmer and some basic Assembly knowledge you can modify its functionality to suit your needs.

The code is written by Electric Druid who supplies the chips preprogrammed.

Notes: Module A-147-4 is a dual voltage controlled LFO (Low Frequency Oscillator). Each LFO has the five waveforms triangle, sine, rising and falling sawtooth, as well as rectangle available. The rectangle output features manually adjustable pulsewidth and pulsewidth modulation by means of an external control voltage. The core waveform is triangle. The other waveforms are derived from triangle by means of waveform converters. The frequency of each LFO can be adjusted manually and modulated by means of an external control voltage with associated attenuator and polarity switch. By means of a jumper the basic frequency range of each LFO can selected: about 0.02 Hz (~ 50 seconds) ... 2.5kHz or about 0.0017 Hz(~ 600 seconds) ... 220Hz. That way each LFO can be used also as a VCO with a max. frequency of about 2.5kHz. Each LFO features a reset input which can be used to reset the triangle signal.

The module has these controls and in/outputs available:

Control F : manual control of the frequency, for each LFO the frequency range can be selected by means of a jumper from two values (see technical notes)

frequency coverage of control F in the high frequency range: about 0.075 Hz (~ 13 seconds) ... 1,4kHz

frequency coverage of control F in the low frequency range: about 0.007 Hz (~ 140 seconds) ... 125Hz

Control CV: attenuator for the signal applied to the CV socket, by means of a jumper a small positive voltage can be applied to the switching contact of the /CV/ socket, as long as no patch cable is connected to /CV/ socket the CV control then works as fine control for the frequency

Switch CV Pol.: polarity switch for the signal applied to the socket /CV/

Control PW/PM: combined control for manual and CV control of the rectangle pulsewidth:

when no patch cable is connected to socket /P/ the control is used to adjust the pulsewidth (PW) manually

when a patch cable is connected to socket /P/ the control works as attenuator for the external CV signal with a basic pulsewidth of 50:50.

Socket /CV/: frequency control voltage input, in the factory the module is adjusted so that the sensitivity of this input is exactly 1V/octave when the CV control is fully CW.

Socket /R/: reset input, according to the associated jumper the reset input is edge triggered or level controlled (see technical notes for details)

Socket /P/: pulsewidth control voltage input

Sockets with waveform symbol: output of the waveform in question (triangle, sine, rising and falling sawtooth, rectangle)

The output voltage ranges are about -5V ... +5V (10Vpp), except the rectangle output

For the rectangle output one can choose by means of a jumper if the range is about -5V ... +5V or 0...+10V.

The inputs of the module are labelled with white characters on black background (in the text included into two slashes). The outputs are labelled with black characters.
Technical notes and special features:

The basic frequency range of each LFO can be selected by means of a jumper. The settings correspond to two different capacitor values for the VCO circuit. The relation between the two ranges is about 1:11. When the upper range is selected frequencies from about 0.02 Hz up to 2.5kHz can be generated. For the lower range the values are about 0.0017 Hz ... 220Hz. To obtain these full frequency ranges external control voltages are required. With the frequency control F only the frequencies mentioned above are possible.

Apart from that the range for the manual control F can be reduced to obtain a finer resolutuion. For this a jumper has to be removed. The range of control F is then reduced to about 1:4.5 only.

In the factory the starting voltage of the triangle output after a reset is adjusted to 0V, i.e. the triangle starts from 0V with the rising slope after a reset. By means of a trimming potentiometer the starting voltage can be adjusted to another value (e.g. to -5V).

Another jumper is used to set the reset behaviour to edge triggered or level controlled. When set to edge triggered the rising edge of reset signal is used for the reset (independent of the duration of the "high" state of the reset signal). When set to level controlled the triangle output remains at the starting voltage as long as the reset signal is "high". Only when the reset signal turns "low" the triangle starts.

In Through Zero oscillators, frequency is controlled by either positive and negative voltage. If FM CV goes below zero, the core will continue oscillating inverting its phase. This "little" change of behaviour allows the core to create a whole new range of timbres that are just impossible to achieve with regular VCOs.
If you set the module as LFO, the range of funky modulations will be endless!

Notes: A classic all analogue saw VCO core with 3 switchable modes, ART, 1V/Oct, LFO and is recommended as the basic building block for ART systems. It is designed for patching analog polyphonic synths from discrete modules or multi-mono patches in ART mode. When using ART the ATX1 takes care of the tuning including accounting for temperature changes. In 1V/Oct mode the ATX1 runs as a standard old school modular VCO. LFO mode drops the frequency range and is great for patching vibrato to other ATX1s among other things. The ATX1 outputs variable waveshapes with manual or CV control. Classic FM, PWM and hard sync are provided. A dedicated Gate Out in ART mode manages the voice envelopes or any modulation synced to that voice. TipTop consider the ATX1 the best sounding analogue VCO they have ever created.

Notes: The Dual LFO Module from Tobinski combines two low-frequency oscillators, each based on Electric Druid technology: the TapLFO3C and the LFO10. This module provides a wealth of modulation possibilities, with flexible synchronization, waveform shaping, and dynamic CV control to suit any Eurorack setup.

The TapLFO3C (left side of the module), syncs to an incoming pulse, allowing precise alignment with external clocks or rhythmic triggers. Its built-in frequency multiplier/divider further extends its range, enabling intricate timing patterns. The output can also be set to +-5v bipolar or 0v to 10v unipolar.

The LFO10-based LFO, on the other hand, resets to an incoming pulse, ensuring repeatable, synchronized modulation. The output can also be set to sample and hold mode allowing the LFO waveform to act as the signal to be sampled and the reset pulse to act as the sample trigger.

Each LFO features 16 selectable waveforms split into two banks of eight, accessible via manual switches.
