Utilities & PSU cause & effect / voltage reader, sample & hold and gate switch / 4 HP & 20 HP ⇣ Introducing the Cause & Effect module – the maestro of musical mischief in your Eurorack setup. It's like the conductor of a whimsical symphony, where flipping switches and twiddling knobs creates a chain reaction that turns chaos into pure sonic magic. Who knew that cause and effect could be this much fun? 1/6 key features Three Utility Tools Voltage Reader for Gates Hold for Sampled Voltages Gate Switch Gate Switch Inverter Two Hold Modes Inputs Normalised Accepted input voltages for all inputs: -8V to +8V (CV & Audio). Available in Intellijel and Pulp Logic Tile Format Skiff friendly specs & downloads width: 4 HP & 20 HP depth: 30 mm power: 35 mA @ +12V / 31 mA @ -12V documentation videos description / manual The first unit is a VOLTAGE READER, that outputs a gate signal according to a limit set with the help of the READ LIMIT potentiometer. If the limit set (any voltage between -6V and +6V) is reached by the incoming voltage, the R GATE output will be high. The limit may also be controlled via external control voltage at the LIMIT CV jack. This so-called comparator outputs a gate with an amplitude of +/-5V, which also makes it usable as a square wave generator with pulse with modulation via the READ LIMIT potentiometer. Any voltage applied to READ IN is normalised to HOLD IN and IN A. R GATE is normalised to H GATE and SW GATE. This way only one signal is necessary to control both other units. The second unit is called HOLD. In one mode it can sample and store a voltage from the HOLD IN jack and supply it at the HOLD OUT jack, if gate at H GATE is high. In another mode it can pass through the incoming voltage when gate is high. It then samples and stores the last voltage value applied when gate switches to low. The modes are selectable via the HOLD MODE switch. The third unit is a GATE SWITCH. Apply a gate signal to the SW GATE input to route IN A or IN B to OUT. If the gate signal is high, IN A is switched through, and if the gate signal is low, IN B is switched through. When only IN A is connected and IN B is not, OUT produces an inverted version of IN A when the gate is low, and a non-inverted version when high. When only IN B is connected and IN A patched with a dummy cable (a cable that is not connected to another module), IN B can be switched off by a gate signal. If nothing is patched to IN A, the VOLTAGE READER GATE output is normalized to this input. This module is available in 3U and 1U!

Oscillator yaksha´s fate / mutable instruments "rings" adaption / 8 HP ⇣ In this rendition, the emphasis was placed on showcasing all the adjustable parameters prominently while concealing those that could impact tuning and harmonics. This design approach allows you to immerse yourself in uninhibited live performance, without the concern of inadvertently altering frequency or structure, ensuring a seamless experience for both you and your audience. 1/3 key features Please check out the original module by Émilie Gillet which is an all time Eurorack classic already Illuminated Yaksha´s Fate Logo Wrong Polarity Protection specs & downloads width: 8 HP depth: 38 mm power: 125 mA @ +12V / 12 mA @ -12V documentation videos description / manual It has all the functionality of the original module except for the two Outputs Odd/Even, Frequency CV (also Fine Tune) and Structure CV (Harmony). You may switch Filter CV or Decay CV to control Harmony via jumper though. The two outputs Odd and Even are mixed together on the OUT jack, but you can fade from one to the other using the Partial Knob. This way you get an additional sound shaping option and some kind of trigger control when two or four notes polyphony is selected. In contrast to the original Yaksha´s Fate will rather act as a VCO producing a constant tone (through very fast trigs) if you plug a CV source into 1V/OCT without a trigger at the TRIG input.

Mixer & VCA sum v2 / 6-channel mixer with afl, eq, pan and two aux sends. / 28 HP ⇣ An innovative live mixer designed for the Eurorack modular synth ecosystem, featuring AFL listening capabilities. 1/3 key features 6-Channel Mixer Preview Sounds with AFL VOLUME, EQ, SEND and PAN for channels 1-5 MUTE Switches for Channel 1-5 + 20dB Gain per Channel 1 Stereo Input 2 Selectable Send/Return Ways specs & downloads width: 28 HP depth: 35 mm power: 85 mA @ +12V / 65 mA @ -12V documentation videos description / manual Each of the 5 mono input channels has a LEVEL, PAN, EQ, SEND and AFL potentiometer and may be MUTED with a switch. The mono singal will be converted into a pan-able stereo signal. Additionally the GAIN can be adjusted using the little trim potentiometer. Turning the SEND pot will route the signal to a SEND jack in order to integrate external effects. The wet effect signal may be returned in stereo. You can choose between two SEND ways via switch. The send channels can be set to be active either pre or post AFL per channel via a solder bridge. ‚Pre‘ means you can still hear the send/return way when it is in AFL mode (thus the channels signal is actually not audible in the main mix), ‚post‘ means send/return will only work when the channels signal is routed to the main mix. Each SEND channel has a separate GAIN trimmer adjustable from the front. Channels 1 to 5 have an AFL/MIX potentiometer (AFL = after fade listening), which allows you to audit your sounds on the headphones before you add them to the mix. Fully counter-clockwise the channel is only routed to the headphones (AFL), turning it clockwise it will be smoothly subtracted from the headphone out and added to the main mix (Mix). Two LEDs per channel indicate the current state. The MIX TO HP knob routes the main mix output to the headphone out in order to compare the channels that are in AFL mode with the main mix. This can be deactivated with a switch to only audit channels that are currently not send to the main output. The headphone level can be adjusted with the HP VOLUME knob.The EQ will boost high frequencies and cut low frequencies when turning the pots clockwise and vise versa turning them counterclockwise. Additionally there is a stereo input to integrade other mixers, like PHOEBE, SUM or uSUM for example. This channel has no AFL, EQ or SEND. prev Up next

Effects stereo compressor / feedforward stereo compressor / 6 HP ⇣ STEREO COMPRESSOR is a classic analog feedforward compressor, which takes its sidechain split directly from the input signal. It is based on the THAT4305 Analog Engine® single-chip with integrated Blackmer® VCA. 1/3 key features Analog Compressor Stereo Signal Path THRESHOLD, RATIO and GAIN ON/OFF Switch for Signal Comparison Up to +20dB Make-Up Gain STEREO SUM Compatible Skiff friendly Wrong polarity protection specs & downloads width: 6 HP depth: 28 mm power: 35 mA @ +12V / 26 mA @ -12V documentation videos description / manual STEREO COMPRESSOR has two independent signal paths in order to process stereo signals. The left input is normalized to the right, if you want to compress mono signals instead. The module has three controls and a switch: THRESHOLD determins the level at which the compressor starts working. This can be set from -40dB to 20dB. RATIO sets how much the compressor turns down the volume when the threshold is reached (INF:1 to 1:1). GAIN regulates the amount of make-up gain (-20dB to +20dB) that is applied to the signal. Additionally there is an ON/OFF switch that makes it easy to compare the dry and compressed audio signal. Please note that if you turn THRESHOLD counter-clock wise to the left, you reduce the threshold from 20dB (fully cw) to -40dB (fully ccw). Hence the compressor starts working earlier. If you turn RATIO counter-clock wise to the left you increase the amount of compression from 1:1 (fully cw, no compression) to INF:1 (fully ccw, infinite compression). So turning the knobs down corresponds to compressing the signal. The pictures below show the knobs in a neutral position where no compression is applied. STEREO COMPRESSOR has a similar design as the STEREO SUM CHANNEL modules. If you want to add some compression to your mix STEREO COMPRESSOR is a perfect addition to your STEREO SUM Mixer. prev Up next

Oscillator cyllene V2 / classic analog vco with three sub-octaves and internal FM / 10 HP ⇣ The Cyllene module is a fully analog oscillator that stands out with features like three sub-octave layers and internal frequency modulation. It's a versatile sound source designed to deliver rich and complex tones for your modular system. 1/3 key features Classic Analog VCO 4 Waveforms: PULSE, TRIANGLE, VARIABLE WAVEFORM, SAWTOOTH (MOD) 1V/Octave tracking Internal VCA Pulse Width Modulation with Attenuator Internal Frequency Modulation via Modulation Oscillator Up to 3 Sub-octaves Attenuator for each Sub-octave Wrong Polarity Protection specs & downloads width: 10 HP depth: 28 mm power: 26 mA @ +12V / 19 mA @ -12V documentation videos description / manual Cyllene offers four waveform options : pulse wave triangle wave variable waveform (which blends between sine and pulse via trimmer on the back) modulation sawtooth wave. You can select the active waveform using the SELECT knob. This can be done manually or controlled via CV input. An LED shows which waveform is currently selected. To tune the oscillator, use the COARSE knob for broad pitch adjustments and the FINE knob for precise tuning. The V/OCT input allows Cyllene to track pitch from sequencers or keyboards accurately across at least five octaves (1V per octave standard). For added depth, you can blend in up to three sub-octaves with any waveform: The BASE function adds a pulse wave three octaves below the current pitch. The SUB section introduces two additional sub-octaves: one and two octaves below the main pitch. Use the SUB -2 / SUB -1 control to mix between them. In the center position, both are equally present; turning fully left or right isolates one sub-octave. A NOISE control lets you mix in white noise to enhance texture and add grit to the signal. Cyllene also features internal frequency modulation (FM) . Use the MOD FREQ knob to adjust the pitch of the internal modulation oscillator, and the MOD AMT knob to control how strongly it modulates the main waveform. The MOD SYNC switch allows you to unlink the modulation oscillator from the V/OCT input for more experimental FM tones. The pulse width of the pulse wave can be shaped manually with the PULSE WIDTH knob or modulated externally via the PWM CV input with its dedicated attenuator. Lastly, Cyllene includes a built-in VCA , which lets you control the oscillator's volume using an external envelope or control voltage, eliminating the need for an extra VCA module and saving valuable rack space.

Modulation & Random good & evil / chained lfo and random voltage generator / 12 HP ⇣ GOOD & EVIL ingeniously captures both order and chaos within a single voltage generator module. Its versatility extends to controlling numerous parameters in other modules, making it an ideal companion for crafting gradual shifts in ambient soundscapes or venturing into dynamic and evolving patch creations. 1/3 key features Four Chained LFOs Controllable Time Attenuator per LFO Output Four Random Voltages Adjustable Amount of Random and Chaos EVIL CV Input Random Gate Wrong Polarity Protection specs & downloads width: 12 HP depth: 28 mm power: 75 mA @ +12V / 55 mA @ -12V documentation videos description / manual The GOOD side consists of a chain of four LFOs. Each LFOs only starts to rise when its predecessor descends. The four knobs control the time it takes for each LFO to rise and simultaneously controls the time it takes for the predecessor to descend. The LFOs have individual outputs with an attenuator. This row of low frequency oscillators can either create very slow envelopes followed by fast changes, just very slow voltage changes or a chain of fast swinging LFOs with their voltage never being the same on the four outputs at a time. The EVIL side generates random voltages that can be influenced by the knobs EVIL 1 and EVIL 2. These change the amount and amplitude of chaos being created. The voltages may move very slow, but also evolve to a burst of changing voltages over the course time. Just like on the good side there are also four outputs on the evil side. Additionally there is a GATE output that provides random gates in conjunction with the EVIL voltages. The EVIL CV input gives voltage control over the amplitude of chaos. An attenuator may lower the amount of voltage being inserted to the EVIL side. The last LFO of the GOOD side is normalised to the CV input of the EVIL side, if no patch cable is inserted into EVIL CV. The voltage range is between +/-3V for GOOD and +/-10V for EVIL. The EVIL outputs usually wobble and meander around +/-2V, but also show peaks of +/-5V, and +/-10V (expecially output V). Using the EVIL CV input forces the circuit to generate peaks more frequently. The gate has a voltage of approx. +6V. prev Up next

Utilities & PSU cv expert / dual polarizer, offset & gain with LFO / 4 HP ⇣ CV EXPERT is a very compact yet powerful CV tool that is equipped with all the important functions you need to customise your control voltages. With its internal LFO, it is immediately ready for use without further patching. 1/3 key features 2x Polarizer 2x Offset 2x Gain Triangle or Square Wave LFO Internal normalizations Low HP format Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 50 mA @ +12V / 32 mA @ -12V documentation videos description / manual CV Expert (Cve) is a versatile dual-channel tool for customizing control voltages. Its internal LFO is normalised to both inputs and allows you to choose between a triangle or square wave via a jumper on the back. The LFO connection is automatically interrupted when an external CV is inserted. Adjust the LFO rate with the LFO RATE potentiometer. The signal received at the DC-coupled inputs IN ① and IN ② passes through three CV tools: Polarizer The PLRZR potentiometer enables voltage attenuation and inversion. At the midpoint, the signal is eliminated. Turning to the right allows the original voltage to pass through (as with an attenuator). Turning to the left inverts the signal, e.g. positive signals are converted into negative signals. Offset Adds or subtracts voltage from/to the passing signal. OFFSET control determines the offset range. In the center position, there is no voltage offset. Turning the control to the right shifts the voltage to the positive range, while turning it to the left shifts it to the negative range. Gain Amplifies the signal with a maximum gain of 2 at the GAIN control's maximum position, effectively doubling the applied voltage (e.g., +1V becomes +2V, +3V becomes +6V, or +4V becomes +8V). The voltage is capped at a maximum of +/-10V. CV EXPERT QUICK START GUIDE: CVE_QUICK_START .pdf Download PDF • 422KB prev Up next

Effects clipping cat / vactrol distortion with diode clipping & lpg / 4 HP ⇣ CLIPPING CAT will make your sounds meow! It's a Vactrol-based distortion that will easily cram a lot of filth and grit into your tone. From sine waves to kick drums, this cat won't miss a scratching post! 1/3 key features Vactrol Distortion Diode Clipping Soft & Hard Clipping „Diode Playground“ for Easy Replacement of Soft Clipping Diodes Vactrol LPG Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 20 mA @ +12V / 20 mA @ -12V documentation videos description / manual Based on the passive and very simple WORKMATE CLIPPING CAT, this souped-up 3U module now features three main controls. GAIN determines the amount of distortion applied to your signal. LEVEL decreases the signal level that is fed into the circuit and the CAT/NO CAT switch activates or deactivates the additional diode clipping function. You can choose whether you want hard (CAT) or soft clipping (NO CAT). Depending on the diodes you solder in, the clipping behaviour and sound will change drastically. CLIPPING CAT will only blink and meow if you set the switch to "CAT" and have set a good amount of gain. The amount of gain can also be voltage controlled using the CV GAIN input socket. Each incoming CV signal can be attenuated with the corresponding potentiometer. The overall gain range can be adjusted using a trimmer on the back of the board. This CV functionality also allows CLIPPING CAT to be used as a low-pass gate with the smooth vactrol-based behaviour we all love. Another trimmer allows the circuit to be optimised for LPG or distortion purposes. To simplify the exchange of diodes for soft clipping mode, there is a "diode playground" on the back of the board where you can easily exchange through hole diodes . Feel free to experiment with different types of diodes and discover novel distortion sounds. Purr! prev Up next

Modulation & Random envelope / cv envelope generator / 12 HP ⇣ ENVELOPE presents a classic ADSR/AR envelope generator elevated by advanced controls and shaping capabilities. Tailored for crafting diverse envelopes, it offers precise adjustments that result in dynamic control voltages, adding an organic and captivating dimension to your sounds. 1/3 key features ADSR/AR Envelope CV Control over all Stages Attenuator per CV Input Shape Control for Attack, Decay and Release Internal Envelope-Controlled Amplifier Loop Function Internal Modulation 0V to +10V Range specs & downloads width: 12 HP depth: 30 mm power: 56 mA @ +12V / 36 mA @ -12V documentation videos description / manual The length of each ADSR stage can be changed with four slider potentiometers. Times range from 1ms in FAST MODE to half a minute in SLOW MODE. The FAST MODE allows a very fine adjustment of short envelopes, which is especially handy for creating percussive sounds. There are dedicated SHAPE potentiometers for the ATTACK, DECAY and RELEASE stages. With these you can switch from exponential to logarithmic response curves. Each phase has its own CV input to control its timing. Dedicated attenuators allow you to adjust how much voltage is applied. The slider LEDs indicate if a voltage is being processed and if the timing of a stage is being changed. If nothing is patched to the CV inputs, the attenuators suppress the portion of each stage's voltage that is passed to the OUTPUT jack. This allows you to quickly change the envelope without changing the original slider settings. In addition, there is a CV input RF CV to control all rising and falling stages at once (without LED indication). ENVELOPE also has an internal GATE and MODULATION source. When the LOOP/RESET switch is set to LOOP, the envelope is internally triggered at a rate set by the MOD RATE pot. It also allows you to internally apply a TRIANGLE or SQUARE-WAVE LFO to any stage when nothing is patched to the CV inputs and the attenuators are turned clockwise. The rate of the LFO is also controllable with the MOD RATE pot. You can change the waveform of the LFO with the TRI/SQU switch. Setting the LOOP/RESET switch to RESET will reset the internal LFO each time a gate or trigger is received at the TRIG/GATE input. The TRIG/GATE switch determines whether a trigger or gate signal should be applied to the TRIG/GATE input. When you set the switch to TRIG, the envelope type changes to ATTACK and RELEASE only. If you need an envelope that is easy to change, this is the correct setting. GATE mode activates a full-featured ADSR envelope with many adjustment options. In addition to the standard envelope output ENV OUT, there is also an inverted output ENV INV. The voltage ranges of the ADSR outputs are about 0V to +10V for the normal output and 0V to -10V for the inverted output. To complete the packed feature list, ENVELOPE is also equipped with an internal VCA, which is internally connected to the envelope output. Simply connect an audio source to the VCA IN input and you'll have an envelope-controlled signal available at the VCA OUT jack.
