Notes: Terci Ruina combines three classic distortions in 4 hp. Distortions are reinterpreted in classic NE style and routed through each other for complete sonic annihilation of any sound. Patch in and out anywhere in the signal chain to pick the best sound for your purpose (because modular). Looking for a pretty distortion? This is probably not your module. Unapologetically gross and dirty.

Notes: Lipsk facilitates the inversion of the individual bits produced by Drezno (or any other module connected to its input header at the back), and delivers the resulting code to its output header. Bit inversion can be manually controlled by pressing any of combination of its eight illuminated buttons, or it can be automated by patching gate signals into its gate input sockets. An active (5V) gate flips the state of the respective bit. If the button is active (bit already flipped), then the gate flips the bit again yielding double inversion (no inversion). The corresponding LEDs show the combined effect of both manual and gate actions. The bit processing logic is hardware-based, so there is virtually no latency, allowing the binary signals to be manipulated at extreme rates.

Notes: Mixer & CV/clock-controlled Switcher

Focused versatility seems an oxymoron when describing the features that led to the design of the Mixwitch.

With only a pinch of mixing, inverting and controlled switching, Klavis Electronics brew up a plethora of combinations and uses.

This is voltage processing magic!

The Mixwitch design comes from a frustration with attenuvertors (bipolar attenuators-inverters) whose off (neutral) position is difficult to retrieve, especially in live situations.

Klavis went for a digitally-controlled analogue path where polarity inversion would be at the touch of a button. So, the usefulness of attenuating/inverting can be realized by turning the pot down, swiftly pressing the inversion button and reopening the level. The zero level is where you expect it, with the pot full down.

Once a clean polarity control was established, a mute function was added, offering the benefit of pre-adjusted pot settings ready to be activated at will.

The next step was to bring something extra, useful and creative. There are plenty of analogue switches controlled by a clock; but arbitrarily selecting an input with a voltage is less known. Having both control capabilities combined with Klavis' specific mixer features creates a unique fusion: welcome to the Mixwitch!

Notes: The ComPair is a versatile yet compact and affordable tool to expand your sonic arsenal. Voltage comparison is used to trigger events, reshape and mangle waveforms and realize level-dependent logic functions.

Two sections can be used independently as voltage against manual setting comparison. Additionally, the first section allows voltage against voltage comparison with offset adjustment.

When used globally, the module offers a powerful window comparator with CV-controlled top setting.

The outputs benefit from three triple-position switches, allowing independently settable polarity and muting.

Three LEDs indicate the output logic to keep track of what's happening.

Notes: Hat is a hi-hat cymbal with a wild side. Finding something unique is easy with a blend of sounds ranging from robotic to metallic. At its core are three unique sound sources made up of six oscillators, a noise generator, and a number of filters. Sizzle affects each source independently, adjusting oscillator and filter frequencies, allowing for a broad range of sounds. In addition, separate trigger inputs for open and closed allow for a complete hi-hat pattern on a single module. No matter what situation it's in, Hat provides shimmering, metallic timbres for any percussive purpose.

Notes: The TBD module is a multifunctional DSP (digital signal processing) module that includes more than 30 different synthesis and audio processing plugins. It is a collaboration project between CTAG Kiel (an academic working group of Kiel University of Applied Sciences), instrumentsofthings.com (who produce this module for Eurorack) and tangiblewaves.

The module looks quite simplistic with it's only three knobs and three buttons, but the power lies in the web based user interface for editing and storing the parameters. For editing, the module is connected via USB to your computer and a small software tool running here is the bridge to the editing of the parameters via your web browser. IMPORTANT TO KNOW: When the editing is done, the module runs autonomously, without a computer!

Up to 10 favourites can be stored on the module and be chosen by the CONFIG button.

Dynamic control of the modules' parameters works via the two CV inputs and two trigger inputs (which are linked to two buttons), and two knobs are also available for live tweaking parameters. The assignment of inputs/knobs to actual parameters is done in the web based user interface.

Please note that the TBD module has mono audio input and output (compared to the Eurorack version which is stereo); plugins that do stereo audio work also in the AE TBD, but only on one channel. ("Why only mono?" you might ask; the limitation to mono is due to licensing agreements to keep the module price in the usual AE range.

The contained plugins are:

Talkbox (Vocoder), MSxxNoise (MS20 filter and Stone Phaser), Antique (Old Record / Tape Effect), Subotnik (Huge Modulations), VctrSyn, SpaceFX, Formantor, Bjorklund, Karpuskl, APCpp, Retroactor, Rompler (sample playback), WTOsc (custom wavetable), Claude (ported MI granular audio processor), BBeats, CStrip, CStripM, EveryTrim, MISVF, TBD03, PolyPad, TBDings (ported MI resonator), TBDaits (Ported MI Macro Oscillator), TBDeeps (ported MI Wavetable Oscillator), DustLoop, Dust, SubSynth, Sine Source, Simple VCA, SDelay, Plate Reverb, Pink Noise, MiVerb, MiVerb2, MiPShift, MiEnsemble, MiChorus, HiHat1, G-Verb, Freeverb, FBDlyLine, EChorus, Progen Reverb, CDelay

Notes: A compact attenuverting (attenuator-inverter) joystick controller and Gate Generator. With it, you can generate and process two control voltages using only one hand. Provided controls for CV ranges and offset adjust the boundaries of your control, this way it never gets out of the desired range, ensuring sensibility and playability even with wild performance gestures.

Notes: The Flexshaper is a highly versatile module when it comes to modify evolving voltages in other directions and levels.

Five settings allow you to fold/expand/clip/compress/invert partially or completely any CV or audio signal.

The module can act as an envelope-shaping tool, frequency multiplier, waveshaper, clipper, distortion, limiter, curve changer, and more.

Five CV inputs offer limitless control over the placement of the voltage points for dynamic signal sculpting.

Birth of the product

The idea of the Flexshaper comes from a feature in the Oberheimr Matrix synthesizers called Tracking Generator.

This signal processor was part of the modulation matrix and meant to be virtually inserted between modulation sources and destinations in order to change the shape of the controlling signal.

The Flexshaper applies the same concept using the same 5 shaping points. However, it goes beyond Oberheim's implementation on two main aspects:

It goes fast enough to process signals at full audio rate
The 5 points are dynamically adjustable (CV) in real-time
Besides, the Flexshaper can process adequately bipolar and unipolar Eurorack signals, even changing them one another.

Notes: Befaco's new Output Module is designed to be the master output for your modular system, providing an extra Cue Input to monitor any signal.

Left IN is routed to both channels when no Right signal is present. Both Outputs are TRS balanced.

A Headphones out is available. You can route Headphone OUT to the main out or an independent signal with CUE switch. Like this you can either pre-listen your sounds with the CUE Input or listen to your main out without disturbing your neighbours!

Level LEDs are available to monitor levels of each signal on the module.

Notes: Erica Black Series include high-end, unique functionality and superior quality modules. Only the best, highest quality components are used, all inputs and outputs are protected against undesired overvoltage. When designing Black Series, put Erica Synths prioritised design and usability first Big knobs are assigned to functions that make difference in sound. Erica Black series consist of range of modules that are needed to put together entire synth. Enjoy!

The Erica Synths Black Dual ASR EG is a versatile, full analogue voltage controlled looping envelope generator and low frequency oscillator with manually and voltage controlled shape and rate, designed for use in advanced modular systems.

It has two identical parts, each featuring all typical envelope generator controls and bonus features - the end of the cycle output and bi-polar LFO output. When in loop mode the shortest attack and decay settings turn the module into voltage controlled drone oscillator with adjustable waveform (it will not track 1V/oct, though).

Notes: Designed with versatility in mind, MapVolt is a dual-channel Universal Voltage Processor built for flexibility in handling audio and CV signals.

With only 6hp, Mapvolt is a multipurpose tool for voltage-controlled scaling, inverting, offsetting, subtracting, and mixing functions.

Each channel of MapVolt can operate in either Polarizer or Attenuator mode, allowing manual control via knobs or CV signals. In Polarizer mode, it functions as a Voltage Controlled Attenuator-Inverter, granting control over signal level and polarity. Additionally, it can be used as a Four-Quadrant Multiplier or Ring Modulator for audio signals, with the processor input serving as the carrier signal and the polarizer's CV input acting as the modulator.

In Attenuator mode, MapVolt operates as a VCA, providing control over signal levels. Its VCA CV input range of +5/-5 makes it well-suited for amplitude modulation (AM) with other +/-5V waveforms.

MapVolt is equipped with dedicated Voltage Offset knobs for each channel, which can be controlled via CV. If no input is patched into the Processor input channel, the Voltage Offset knobs can be used as Offset Generators.

With its dedicated mixing stage, MapVolt enables the combination of both channels into a shared output. Furthermore, if one of the processor channels is inverted, it allows for the subtraction of one signal from the other.

Notes: TriTone is a three section EQ plus saturator. Inner knobs control frequency and outer knobs control +- gain. All these sections Hi Shelf, Band Pass and Low Shelf are having + 20 db of gain and 30 db of reduction. Each section can work independently or they can be serially connected by the switches. Middle input in each section accepts CV for its frequency, so all three sections can be individually FMed by the external CVs.

If the inputs are fed with the modular level signals (+- 5V), then there is little room for "plus" EQ gains before saturation starts. In this case the input level should be attenuated first, if saturation is not desired and much "plus" gain is needed. Otherwise saturation drastically enriches the tone and the module works like very flexible overdrive FX.

When the switches are set to upper positions, then all three sections work independently. With the maximum gain reduction (CCW position) of the upper section (Hi Shelf) it becomes a useful kind of Low Pass filter. On the contrary - maximum gain reductions of the lower section (Low Shelf) makes it a High Pass filter.

Please note the internal routing done by the switches: the output of the uppers section is added to the input of the subsequent lower section. If nothing is connection to this lower sections' input, then only the upper section's output is processed. This makes it a 3 band EQ with the switches set to lower position. Having separated inputs opens up more possibilities over ordinary EQs.

Notes: After Later's first ladder filter is in stereo. You'll get HP, BP. LP2, and LP4 outputs for each side. Please read below on the HP and BP outputs, as they are a bit temperamental.

Along with all of the great traditional sounds of a ladder filter, After Later have added a bias knob which starves ladder transistors of bias current. This can create some fun detuning, glitchy, and warbly sounds. It is recommended that you turn the resonance up slightly in order for it to sound best. Turning the bias will mess with the cutoff frequency and resonance settings so it takes some knob tweaking to master it. There is decent volt/octave tracking for about 3 octaves.

The HP and BP are possible due to pole mixing. When combined with the level control and the resonance it can lead to some atypical behaviours. When keeping the resonance low, and you'll need to manage the level control to get a typical HP and BP responses.

Notes: Each of the two sections of the module is capable of performing the analog multiplication of two signals (A and B) and add an offset (C). It can also act as a dual voltage controlled attenuverter, dual ring modulator, dual VCA or four channel mixer (see block diagram below).

The B inputs are routed to an attenuverter that multiplies the signal between -2 to 2, while the offset inputs (C) route through a unity gain attenuverter (multiplies the signal between -1 and 1).

The output of first section is routed to the output of the second (when the first's output is unused), so the second output can act as master to achieve (A1*B1+C1) + (A2*B2+C2) or (A1 + C1) + (A2 + C2) - a 4 channel mixer.

The through-zero (four-quadrant) multipliers in the A*B+C allow for true Ring Modulation. To achieve this, simply connect two waveforms to the A and B inputs.

Notes: 3xVCA ofers three high class amplifier circuits with linear characteristic. Thanks to AC / DC compatibility, a very low noise floor and basically no distortion, the module is not only a great partner for control voltages, but audio material as well. Besides a signal input and output, each VCA has its own CV input. The dual potentiometers regulate levels and bipolar CV attenuation values of all amplifiers. Using these rather unusual, yet very practical components, it was possible to equip the 3x VCA with a front panel that is only 6 HP wide. Switches allow the user to feed the results of one amplifier to the output of the next amplifier, so we can get 1+2, 2+3, and 1+2+3 outputs mix. Two-colored LEDs visualize CV and output signals.

Notes: Motion MTR allow you to mix, attenuate and invert signals while having clear visual feedback of their levels.

Each channel can function as:

Audio level control with VU meter
CV attenuator with voltage meter
CV inverter with voltage meter
Each input is normalled to 10v, so you can
use each of them to generate fixed voltages.
Also, the outputs of channels 1 and 2 are summed into Out 3 to be used as a mixer.
Patch it wildly to make it work as an attenuverter with offset, as a mixer, a VU meter or a combination of them all!
This module is our first collaboration with Robin Vincent from Molten modular.

Notes: A-135-2 is a miniature version of the A-135-1. Behind a front panel with 8 HP only four linear VCAs (voltage controlled amplifiers) and a voltage controlled mixer based on the VCAs are available.

Controls, In/Outputs and Functions of each VCA:

Level (manual control of the VCA amplification), small rubberized knob (L1...L4)

Control voltage input with associated attenuator (CV1...CV4), for the full VCA control range about 0...+5V control voltage are required (attenuator fully clockwise), for higher control voltages the attenuator is used, the attenuators are without knobs, just plastic shafts with white marker

Signal Input

Signal Output

All inputs and outputs are DC coupled. Consequently the VCAs can be used to process both audio and control voltages (e.g. to control the level of LFOs or envelopes)

The signal input is not equipped with an attenuator. But the VCAs can process all signals up to 15Vpp / -7.5...+7.5V without clipping. In case of higher levels an external attenuator is required (e.g. A-183-1).

The available amplification range is 0...1, the maximal amplification is 1 (i.e. it "clips" and remains at 1 even if the control voltage goes beyond the value that corresponds to amplification 1)

Functions of the voltage controlled mixers:

two outputs ("Selected" and "All")

Selected output: the ouput if a VCA is removed from this sum signal when a plug is inserted into the corresponding VCA output.

All output: sum of all VCA outputs, regardless of inserted plugs into the VCA outputs

The maximal amplification is about 0.6 to avoid clipping at the mixer outputs (otherwise the outputs may distort with 15Vpp signals at each signal input and full amplifications)

Special functions of the voltage controlled mixer (selectable by internal jumpers)

Dual Stereo VCA: In this case the control unit of VCA1 (L1 + CV1) affects also VCA3 and the control unit of VCA2 (L2 + CV2) affects also VCA4. The control units of VCA3 (L3 + CV3) and VCA4 (L4 +CV4) are out of operation.

Quad VCA: In this case the control unit of VCA1 (L1 + CV1) affects all four VCAs. The control units of VCA2, VCA3 and VCA4 are out of operation. In this mode the module has the same function as module A-132-2. That's why module A-132-2 will be discontinued.

Normalling of the signal inputs: by means of internal jumpers signal input 1 can be normalled to signal input 2, signal input 2 to signal input 3 and signal input 3 to signal input In 4. That way the same input signal can be distributed to four different channels by means of control voltages (e.g. quadrophonic distribution of audio signals). Suitable control voltage sources are e.g. A-144 (Morphing Controller) or A-143-9 (Quadrature LFO).

Additional technical specification for each VCA (based on the specifications of the VCA circuits CEM3360/AS3360 used in the module):

Crosstalk between VCAs: typ. - 80dB

Signal attenuation at 0V CV: typ. -70dB

Total harmonic distortion: typ. 1%

Control voltage feedthrough: max. 15mV

Notes: The SetonixSynth/Tidbit Audio Psychedelic Voltage Processor, or PVP, is a four-channel chaos module. It uses colour-changing LEDs to produce fluctuating voltages in response to the Channel input, with each channel normalized in series to create increasingly chaotic "taps" that can be used one after another for different variations.

Any positive voltage input such as unipolar LFOs, envelopes, stepped voltages, or simply the onboard normalized voltage patched to a channel input is reproduced approximately on each channel output, with the PVP inducing unpredictable fluctuations due to the variable current consumed by an LED circuit with a mind of its own.

Notes: Module A-188-9 is a so-called high speed VCO that tracks perfectly to the 1V/oct scale in the frequency range of about 15kHz ... 500 kHz. The main application is the exact drive of BBD modules (A-188-1/2) to generate sounds realized by means of the so-called Karplus-Strong synthesis. But even in cooperation with other modules featuring high speed inputs (e.g. digital noise, delay, frequency divider) the A-188-9 makes sense. In principle the module is made of a precision audio VCO followed by a PLL (phase locked loop) unit that multiplies the frequency of the audio VCO by 32. Thus the module can be used also as an audio VCO as it features the standard waveforms sawtooth, triangle and rectangle with adjustable pulse width.

Controls:
Frq: frequency control (coarse)
CV: attenuator for the frequency control input CV
Fine: frequency control (fine), small control without knob
PW: pulsewidth control for the rectangle output of the audio VCO, in HSVCO mode this control has to be in the range marked "HSVO", small control without knob

Sockets:
1V: frequency control input 1V/oct scale
CV: frequency control input with attenuator CV
socket with rectangle symbol: rectangle output of the audio VCO, the pulse width of this output is adjusted by means of the control PW, output level ~ 7Vpp (~ -3.5V/+3.5V)
socket with sawtooth symbol: sawtooth output of the audio VCO, output level ~ 7Vpp (~ -3.5V ... +3.5V)
socket with triangle symbol: triangle output of the audio VCO, output level ~ 7Vpp (~ -3.5V ... +3.5V)
socket with inverted comb symbol: high speed VCO output, waveform rectangle, output level ~ 5Vpp (~ -2.5V/+2.5V)

Switches:
Range
upper position: audio VCO mode (frequency range of the audio VCO about 15 Hz to 6 kHz, the high speed output is not usable in this mode! )
lower position: High Speed VCO mode (frequency range of the high-speed output about 15 kHz ... 500 kHz, frequency range of the audio VCO about 500 Hz ... 15 kHz), in this mode the audio VCO and the high speed VCO can be used simultaneously

Slew
upper position: medium slew time
centre position: short slew time
lower position: long slew time
Technical Note regarding the Slew parameter:

Besides the audio VCO the module contains a so-called PLL circuit (Phase Locked Loop) and a 1:32 frequency divider. A slew limiter is part of the PLL. It defines how fast the frequency of the PLL follows the frequency of the VCO. The PLL cannot follow the VCO without any delay. Rather one has to find a compromise between the residual ripple of the PLL frequency and the frequency follow rate. That is the job of the slew limiter (works in principle like a glide or portamento unit). For this the module is equipped with a 3-position switch that is used to switch the slew time in 3 ranges. When mostly higher frequencies are used ((~ 100kHz ... 500 kHz) a short slew time can be chosen. When also lower frequencies are required (< 100kHz) a longer slew time may be used to reduce the residual frequency ripple. More details about the working principle of a PLL can be found in the information about module A-196. Module A-188-9 is in principle an A-196 combined with an audio VCO and a 1:32 frequency divider.

Notes: The insert module allows you to connect stereo effects to your CGM setup, either by inserting them between two points of the internal summing bus or by placing them in parallel, as in a rudimentary stereo send-and-return.

It consists of two couples of outputs and inputs with dedicated gain switches. The first O/I stereo couple is the insert circuit, while the second is the parallel circuit.

The Insert module can be used:

between a group and a master;
between a group and a group;
between a channel and a group;
between a channel and a channel;
between a channel and a master (without a group).
The Insert module ships with two Insert cables compatible with every member of the CGM family, including the discontinued ones.

Flexible placement

The insert can effortlessly sit between every CGM module. Use it between a group and a master as an end-of-chain bus, or between two series of channels of the same group to create a channel subgroup with independent solo-in-place controls.

Stereo insert circuit

This circuit overrides the internal summing bus and allows you to route whatever sum goes into the insert module through your favourite stereo effects.

Stereo parallel circuit

A second out-in circuit remains parallel to the main one, excellent for adding stereo ambiance effects to the main sum.

Gain switches

The outputs and inputs provide three degrees of attenuation and matching amplification to scale the signal to most of the audio equipment out there.

Notes: Add-on for the Krait module.

Ewa was created as a lovely partner for the Krait module, a syncable 3-channel modulation source. Paired with Ewa, Krait will get new useful abilities, such as 3 freely routable cv inputs, endless encoder for smooth editing without value jumps, dedicated clock menu button and clock and reset outputs.

Each CV input can be used to record external cv source in Record mode. Beside that you can route any input to any parameter of the LFO and Random too. With Ewa now it is easy to modulate LFO rate or Random slew for example. CV inputs are bipolar and react to the signals between -5 +5 voltages.

Additionally a dedicated clock menu button and clock output can make Krait as a clock source for other modules in your system that need sync.

Notes: Winnows, a dual VC resonant filter with damping.

Winnows brings radical resonant filtering to the 1U row. Make your basslines growl like it's 1999. Create clean resonant tones and layers, tuned percussion, steep filtered peaks, vowel filters and more. Each filter channel comprises two state variable filter cores, the first producing a 2-Pole band-pass response, with resonance and self-oscillation amounts set by a 3-Pole feedback network. Signals are then routed through a 1-Pole low-pass damping stage to remove harshness if required. This can be routed to the channel output, or switched and routed through a second series of resonant SVF and 1-Pole LPF damping stages. This circuitry is identical per channel.

Features and uses

Steep and spiked or wide and smooth, resonant bandpass filters
Zone in on and reinforce a sound's dominant frequency, create overtones using both channels
Create sharp resonant peaks, dull or remove any harshness with VC damping
Use the resonator as a sound source by shaping and triggering tuned percussion tones or kick drums
Per channel: 2 x VCA based SVF, 2 x 1-pole damping LPF, 1 x 3-Pole resonance core
Identical circuitry per channel, CV and audio jacks are normalled between channels
Combine both channels in series for vowel filter responses and creative filtering

Notes: CONTROL PATH is an all in one voice dynamics module that helps build full voices quickly. It contains two analogue envelopes with velocity cv, and one VCA. In a typical voice patch the left envelope will control a filter and the right envelope will be the voice VCA. Velocity control is provided for each envelope and delay front panel trimmers are used to compensate for any miss match between incoming gate signal and velocity CV timings. Envelope cv outs are 0-5V, Velocity cv ins are 0-5V.

Notes: Rack power bringing 2.5A (2500mA) on both the +12V and -12V rails. There is a 5V rail, but it pulls from the +12V rail, up to 750mA. So only use the +5V rail if you have to.

Comes with 12-position flying bus cable and wall power supply. The wall power supply is the same unit as After Later Audio use on their cases, so there's plenty of headroom and you don't have to worry about memorizing which amperage is for which.

This should be roughly enough for 2 rows of modules in a 104hp case. If you just need power for 1 row, check out our Warp Drive module.

Notes: HN VCF is a state variable filter having 12 db Low Pass, 12 dB High Pass, 6 dB Band Pass plus 18 db Low Pass marked as "LP!", because it has extra drive. All three parameters: "Freq", "Resonance" and "Drive" have dual knobs with outer knobs controlling bipolar CV amount. These affected CVs are then shown by the relative green/blue LEDs.

The possibility to have CV over "Resonance" and "Drives" makes it a very capable 6 HP filter.

"LP!" output has 6 dB steeper slope (18 dB) compared to ordinary 12 dB "LP" output. Plus it has much more drive.

Notes: The CP909 is the TR-909's analogue clap sound generator in Eurorack format. This is yet another low-cost analogue drum generator from a legendary drum machine in your modular synthesizer, expanding your Tiptop Audio modular drum machine even further.

The CP909 is an exact reproduction of the original analogue circuit and with the addition of just one extra knob, "trashing" the frequency of the internal noise generator, Tiptop have added greatly to the spectrum of sounds that can be generated. All that without compromising the signature sound of the TR-909.

The CP909 clap effect is made by a special triple-saw envelope generator that controls the gain of a VCA. The sound source feeding into the VCA is made by a quasi-random logic- based noise generator. Some might call it "digital noise", though this term might be misleading in today's world of microcontrollers and sound samples. What really makes the noise generator is a ring of logic gates, so primitive, so 80s, and so much the sound of the 909 Clap!

The CP909 includes a high-powered output gain stage capable of producing hot signals. On the inputs, Tiptop have designed a pulse-shaper circuit so you can trigger the CP909 with trigger/gate signals from step sequencers, clocks, dividers, or any other pulse/clock sources. This eliminates the need to shape pulses sent to the module and ensures the same stable sound at peak power, regardless of your pulse source. Based on the architecture of the 909, the Accent input is versatile and able to take in both CV and Gate signals for continuously changing dynamics.

Notes: By combining a mixer and four VCAs in a single module, Mix 3 manages to provide a unique combination of compact size and functionality in just 6 HP. High-end signal paths ensure extremely low noise and distortion, wide headroom and precise gain control, despite the small form factor.

Each of the three main channels has an exponential response, which is more natural for audio than linear, as it matches the human hearing. However, all signal paths are DC-coupled, so control voltage (CV) signals can be processed as well.

What truly sets Mix 3 apart from other compact mixing modules are the three CV inputs, providing voltage control over the signal levels. This even allows you to go beyond unity gain and reach up to +20 dB of amplification. Once a CV input is used, the corresponding channel knob becomes a CV attenuator.

When clipping, Mix 3 does so in a clean, symmetrical way. This yields a very pure overdriven sound, only containing odd harmonics, and allows the module to be used as a triple voltage controlled distortion.

Additional features include audio indicator LEDs, a fourth auxiliary input, voltage control over the output level and a line output jumper setting.

Notes: Super Sawtor is the module designed to produce unison like waveforms from the incoming signal. The best results are achieved using sawtooth, triangle or sine waveforms as an input signal. Unison spread has been tuned to give almost the same type of harmonics smearing as the famous Roland JP80X0 Supersaw oscillator. Thus feeding the Super Sawtor with a sawtooth waveform will result in a typical Supersaw output.

Though having some common features with sawtooth animators, Super Sawtor gives that vivid tension of the Supersaw waveform, which is different to imitation of the multiple oscillators sound most sawtooth animators capable of doing. The main difference is in the approach used: sawtooth animators tend to recreate continuously moving phase shift of the slightly detuned / drifting oscillators; super Sawtor in its turn creates additional pitched shifted harmonics to the input signal, which gives a different sonic character compared to sawtooth animators.

It is also should be mentioned that Super Sawtor is a completely analogue circuit free of aliasing.

No external modulation sources are required for proper operation of the module. However the user can add changes and modulation to the manually set "Spread" amount by using "Cv" input and adjusting "Cv" knob to the desired degree.

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

For each quantizer the following in/outputs are available:

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

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

Typical applications:

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

Notes: Inamp is a dual pre-amp in just 4 HPs. Featuring 6,3 Jacks inputs as well as Minijacks.

Both inputs are summed so you can use them at the same time as an input mixer.

The unit is designed to amplify up to x20 the input signal, allowing to amplify most of the music machines out there (Domestic line levels) as well as some guitars (Humbucker-like pickups and so).

The first channel is normalled to second one in series, so it's possible to have two stages of amplification or two separate ones.

Notes: Module A-192-2 contains two independent CV/Gate-to-Midi/USB interfaces. For each of the two sub-units these inputs are available:

- Gate Input (min. +5V)
- CVN Input (defines the Midi note number), 1V/octave standard, range 0...+10V (i.e. 10 octaves)
- CVV Input (defines the velocity value assigned to the Midi note message), can be used alternatively for Midi volume (CC#7), range 0...+5V
- CVC Input (free assignable to any Midi control change number), range 0...+5V

For both sub-units a common CV Transpose input is available (1V/octave, range 0...+10V). The voltage applied to this input is added internally to CVN before the Midi note number is generated. It can be used e.g. to transpose two sequences simultaneously by one voltage.

How it works:

Whenever the rising edge of the Gate input is recognized a Midi note on message is generated. The note number corresponds to the sum of the voltages applied to the CVN input and the common CV Transpose Input that is present at the rising edge of the gate signal.

Notes: A-135-2 is a miniature version of the A-135-1. Behind a front panel with 8 HP only four linear VCAs (voltage controlled amplifiers) and a voltage controlled mixer based on the VCAs are available.

Controls, In/Outputs and Functions of each VCA:

- Level (manual control of the VCA amplification), small rubberized knob (L1...L4)
- Control voltage input with associated attenuator (CV1...CV4), for the full VCA control range about 0...+5V control voltage are required (attenuator fully clockwise), for higher control voltages the attenuator is used, the attenuators are without knobs, just plastic shafts with white marker
- Signal Input
- Signal Output
- All inputs and outputs are DC coupled. Consequently the VCAs can be used to process both audio and control voltages (e.g. to control the level of LFOs or envelopes)
- The signal input is not equipped with an attenuator. But the VCAs can process all signals up to 15Vpp / -7.5...+7.5V without clipping. In case of higher levels an external attenuator is required (e.g. A-183-1).
- The available amplification range is 0...1, the maximal amplification is 1 (i.e. it "clips" and remains at 1 even if the control voltage goes beyond the value that corresponds to amplification 1)

Functions of the voltage controlled mixers:

- Two outputs ("Selected" and "All")
- Selected output: the ouput if a VCA is removed from this sum signal when a plug is inserted into the corresponding VCA output.
- All output: sum of all VCA outputs, regardless of inserted plugs into the VCA outputs
- The maximal amplification is about 0.6 to avoid clipping at the mixer outputs (otherwise the outputs may distort with 15Vpp signals at each signal input and full amplifications)

Special functions of the voltage controlled mixers (selectable by internal jumpers):

- Dual Stereo VCA: In this case the control unit of VCA1 (L1 + CV1) affects also VCA3 and the control unit of VCA2 (L2 + CV2) affects also VCA4, the control units of VCA2 and VCA4 are out of operation
- Quad VCA: In this case the control unit of VCA1 (L1 + CV1) affects all four VCAs. The control units of VCA2, VCA3 and VCA4 are out of operation. In this mode the module has the same function as module A-132-2. That's why module A-132-2 will be discontinued.
- Normalling of the signal inputs: by means of internal jumpers signal input 1 can be normalled to signal input 2, signal input 2 to signal input 3 and signal input 3 to signal input In 4. That way the same input signal can be distributed to four different channels by means of control voltages (e.g. quadrophonic distribution of audio signals). Suitable control voltage sources are e.g. A-144 (Morphing Controller) or A-143-9 (Quadrature LFO).

Notes: PRO Expanders:

Extra Pam Outputs.

ALM034-EX

PPEXP1 & PPEXP2 are two expander modules for Pamela's PRO Workout that both offer additional dedicated fixed clock, Din Sync & MIDI clock outputs.

Extend Pam as a master to clock external gear with super solid dedicated MIDI & Din Sync clock outputs. The Din Sync clock (x24) and Run outputs can also be patched into a 2nd Pam to easily sync it.

Use the extra fixed clocked gate outputs to free up Pam's main outputs for unique sequencing or complex modulation duties.

Connects directly to and is powered by the 'MIDI-EX' expander header on rear of Pamela's PRO Workout.

Only a single output expander is supported at any time but either can be used alongside an AXON-1 CV input expander.

A MIDI adapter cable and a Din Sync adapter cable are both available for connecting to 5 pin 'Din' type connectors. The PPEXP 1 includes a MIDI Din adapter cable.

Notes: KR is based off of the concept of a guitar tonestack: you get a gnarly drive on the top and a super clean two-band shelving EQ with switchable midpoint after that. There are separate ins and outs, too, so if you want to EQ a thing and distort the other thing at the same time you can!

Kith Ruina's inspiration comes from the world of guitar amps. A drive into an EQ is an extremely common configuration for shaping guitar tone, and we find that it works extremely well for synths as well. A grungy drive into a pristine EQ gives excellent tone control, and with separate ins and outs for the two sections KR can be configured to fit into any patch you throw at it.

Notes: Simple but effective four-channel module, allowing you to attenuate or offset CV or audio signals. Normalled 5V source on each channel allows you to generate a standalone CV signal without an input.

Supplier notes:

4TTEN (pronounced either ATTEN or FOUR-TEN) is a four channel attenuator and offset generator.
Use 4TTEN to attenuate any CV or audio signal by running through the ins and outs.
A +5V voltage source is normalled to each input, making it a standalone offset when there is no cable patched into an input.
Each channel is completely independent.
Ever-so-useful in live performance, we designed this module with 4 sliders for easy maneuverability, visual feedback, and enjoyable to play interface. Make your eurorack modular synthesizer system more playable with 4TTEN!
