Oscillator chiasso v2 / analog fm drum synth / 14 HP ⇣ CHIASSO V2 stands as an exceptional oscillator, perfect for generating dynamic Techno sounds that consistently captivate through each knob adjustment. In its V2 iteration, it retains the same exceptional sound foundation found in V1. However, V2 introduces innovative enhancements like CV decay inputs and an added noise source for oscillator A, promising even more sonic possibilities. 1/3 key features Two Analog VCOs Two LFOs SQUARE and TRIANGLE Waveforms for OSC and LFO Cross Modulation CV Decay Fade Potentiometer to adjust the Oscillator Mix Trigger and Pitch Normalization Wrong Polarity Protection specs & downloads width: 14 HP depth: 28 mm power: 55 mA @ +12V / 35 mA @ -12V documentation videos description / manual The module has two oscillators that can generate square or triangular waveforms that you can seamlessly crossfade with the WAVE potentiometers. Each oscillator has its own CV decay envelope, a pitch potentiometer and can be triggered with a trigger signal patched to the left TRIG input as well as individually via the left and right TRIG inputs. A fade potentiometer offers the possibility to manually fade between both oscillators to adjust the mix. Noise can be added to the left oscillator A to make it a little dirtier. There are PITCH CV inputs with attenuators for each voice which, although they don´t track exactly 1 V/OCT, are very useful for changing the mood of each signal to create very organic and moving sounds. The audio output of each side is normalised to the PITCH CV input of the opposite side. The left side is connected after the VCA and the right side before the VCA to achieve different types of cross-modulations and to apply modulation according to incoming trigger signals. In addition, the module has two individual LFOs with square or triangular waveforms that can be fed to the oscillators for further frequency modulation synthesis. Both LFOs have an attenuator to adjust the strength of the modulation and a RATE potentiometer to change the speed of the LFO cycle. The signals of the two oscillators are mixed and output at the OUT socket. prev Up next

Modulation & Random yace / cv decay envelope / 6 HP ⇣ YACE is a fully featured decay envelope with voltage controlled decay length. It offers the best you can expect from a simple decay module and is a great companion for controlling other VCAs, filters or sound-changing oscillator controls. 1/3 key features Decay Envelope CV Control CV Input Attenuator Level Control Response Knob and Range Switch Cycle Function Gate Mode specs & downloads width: 6 HP depth: 28 mm power: 81 mA @ +12V / 36 mA @ -12V documentation videos description / manual A trigger or gate signal at the GATE socket (INP in the picture) starts the decay envelope and a corresponding CV is output at the OUT socket. An inverted version is available at the INV socket. With the DECAY slider you can change the decay time manually or by CV. With a CV attenuator you can control the level of the length change by CV. The DEC LVL potentiometer controls the level of the decay and is great for controlling filters. A jumper on the rear panel lets you choose whether the DEC LVL potentiometer affects only the regular decay output or also the inverted output. With the RESPONSE control you can change the response curve from very snappy to rather long and soft. The RANGE switch offers three decay length ranges, from fast decay for drums to very long decay curves for slowly evolving sounds. The INP switch changes the input mode from trigger to pulse. Pulse mode adds a sustain stage to the envelope that holds the envelope as long as the incoming pulse is high. The CYC switch activates a cyclic mode where the decay restarts when it reaches its end. In addition, an EOC (End Of Cycle) pulse is output at the EOC socket. With the INFLUENCE input (marked by a curved arrow pointing upwards) you can further change the decay level. Connect an LFO or triggers here to create attacked and more organic decay envelopes. It only responds to voltages above 5V. 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.

Utilities & PSU pedal pal stereo / fx pedal integration module / 8 HP ⇣ Enhance your creative palette by seamlessly integrating your favorite guitar FX pedals into the realm of Eurorack modular. Take command over the amount and tone of the signal sent to your pedal and manipulate the expression pedal input using CV. To double the excitement, this module can handle stereo signals! 1/3 key features Stereo FX-Pedal Integration Expression Input CV Send CV Send and Return Level Controls Send Tone EQ Dry/Wet Control TRS Connections to FX Pedal Use it with Line or Modular Levels Boost Dry and/or Wet Signals with a max. Gain of +20 dB Phase Inversion Switch Skiff friendly Wrong polarity protection specs & downloads width: 8 HP depth: 30 mm power: 59 mA @ +12V / 43 mA @ -12V documentation videos description / manual Connect a stereo or mono signal to the IN sockets (a mono signal to IN L is normalized to IN R), and retrieve the output signal from the OUT jacks. Link your FX pedal's inputs to the SEND output using a TRS audio cable, and connect the FX pedal's output to the RTRN return socket with another TRS audio cable. Fine-tune the blend of dry and wet signals with the central DRY WET knob. The level gain of the dry and the wet signal can be adjusted independently via trimmers on the back of the module. Rotate SEND to the right to increase the audio level sent to the pedal's input. The attenuator beneath the SEND CV jack controls the maximum send signal level, so remember to turn it to the right to activate the SEND jack. Increase the RETURN knob to control the effect signal's level returning from the FX pedal. Be cautious as the send signal can potentially overload the FX pedal's input, so adjust the send amount with care. Both the SEND and RETURN controls provide precise control over the signals sent to and from the effects unit for clean or slightly overdriven signals. The ST Modular logo LEDs indicate whether a signal is being sent from or returned to the module. Turn the TONE knob to the right to emphasize high frequencies or to the left for low frequencies in the SEND signal. Keep it in the center position to have no further effect. Activate the PHASE button to align the audio return signal with the dry input signal if your effects pedal reverses its phase. You may need to make further adjustments to the send and return settings afterwards. The real fun begins when you modulate the amount of audio sent to the FX pedal. Simply introduce a CV signal into the SEND CV input and adjust its level with the attenuator. Furthermore, you can also control the pedal's EXPRESSION input using CV. Connect a TRS audio cable to the EXPR I/O, and the voltage provided by the pedal will be attenuated with the EXPR knob and send back to the pedal, allowing you to manually control the expression parameters. Alternatively, you can patch modular control voltage into the EXP CV input to control the expression parameters of your FX unit, with the EXPR knob acting as an attenuator. The LED indicates when voltage is being forwarded to the pedal. Please ensure you check your FX pedals' specifications before using PEDAL PAL STEREO. Verify whether the pedal supplies its expression voltage on the tip or ring of the EXPR TRS cable and the accepted voltage level (most commonly 3V or 5V). Adjust the corresponding jumpers on the back of the module accordingly. In the video example below, I'm using an EarthQuaker Devices Avalanche Run Delay and Reverb pedal, which provides 3V on the ring of the TRS expression cable. This pedal is particularly well-suited for PEDAL PAL STEREO, as it allows for quick selection of the expression voltage destination, such as reverb amount, delay time, and more. For convenient parameter adjustments, particularly during live performances, potentiometers are positioned on the lower side, ensuring easy access when the module is mounted in the bottom row of a tabletop case.

Sequencer shikensa / cv and trigger sequencer / 12 HP ⇣ SHIKENSA is a 5-stage CV and trigger sequencer with some nifty features. 1/3 key features 5-Step Analog Sequencer Outputs 3 CV and 1 Trigger Signal 3 Different Track Lengths Internal Clock with Swing and Tempo CV External Clock, Reset and Hold ADD Input for Sequence Transposition LEVEL Control via CV for LVL OUT Wrong Polarity Protection specs & downloads width: 12 HP depth: 28 mm power: 55 mA @ +12V / 41 mA @ -12V documentation videos description / manual Shikensa offers the flexibility of an internal clock set via the tempo potentiometer or synchronization to an external clock. Its internal clock enables swing effects through the CLK CV attenuator, allowing tempo adjustment using external CV signals at the CLK CV input. Additionally, CV control permits sequence reset or hold actions. It is possible to change the length of the sequence from a maximum of 5 steps to 4 or 3 steps using a toggle switch. There are five sliding potentiometers that allow fine changes in CV values per step. There is a trimmer on the back of the PCB to adjust the maximum voltage from +5V to +10V. SHIKENSA has a total of four outputs. OUT is the standard CV output that you would connect to a 1V/OCT input of an oscillator. If you apply a control voltage to the ADD input, you can transpose the output of OUT. IN/CK outputs either an inverted signal of OUT or the internal clock signal (this can be changed by swapping two resistors). LVL OUT carries the same signal as OUT, but its level can be changed via CV. An attenuator allows control over the amount of change. When nothing is connected to the LVL CV input and the attenuator is turned up, an internal pitch envelope is added to LVL OUT, which is great for creating percussive sound sequences. These three outputs can be used simultaneously to change not only the pitch of an oscillator, but also other parameters such as waveshapers, filters or effects according to the sequence. TRIG provides a trigger signal that can be activated or deactivated per step. Five latching push-buttons on the bottom allow you to create rhythmic patterns. An LED indicates whether a trigger signal is being output. SHIKENSA QUICK START GUIDE: SHIKENSA_QUICK_START .pdf Download PDF • 716KB prev Up next

Utilities & PSU cv scan / bi-directional cv router / 6 HP ⇣ Unlock unparalleled signal control with our Bi-Directional CV Router. Effortlessly switch between four sources or route one to four destinations. 1/3 key features Bi-Directional CV Router 4 Inputs or Outputs 4 Attenunators Scan Manually or via CV OFF Switch via Push Button or Gate Signal Manual 0V to +10V CV Supply Wrong polarity protection specs & downloads width: 6 HP depth: 30 mm power: 35 mA @ +12V / 21 mA @ -12V documentation videos description / manual CV SCAN is a 1 to 4 or 4 to 1 CV router that allows you to route one cv signal to four different destinations or route four different CV sources to one CV input. This can be done manually or via CV. Additionally the routing can be interrupted via the OFF switch or with the help of a gate signal. Each CV input/output has a dedicated attenuator. There is also a variable -10V to +10V CV supply. The SCAN potentiometer can be used to scan through the different CV sources/destinations. Turning from left to right you will individually activate inputs/outputs A to D after one another. Additionally turning that knob will supply 0 to +10V on the V OUT jack. This allows you to scan through A to D and also change a CV input of another module in accordance to the potentiometer position. RANGE adjusts the inputs and outputs that can be activated with the SCAN knob or the CV input. Applying -5V to +5V in mid position will give you the full range. Turning RANGE counterclockwise causes only A and B to be active. Turning RANGE clockwise will move the activation range from A/B, A/B/C, B/C, B/C/D and C/D. This gives you a nice control over the range to be scanned. The attenuators may lower the signal that is routed through CV SCAN . Pleae note that they are not able to comepletely kill the signal in order to keep the module bi-directional. CV SCAN was mainly designed to handle CV sources. Still it is also helpful to change waveforms of an oscillator for example. This should be done off the mix as there might be small clicks audible when changing sources/destinations. 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 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.

If a signal passes the internal quality evaluation the search is ended and the radio signal is available at the OUT socket. If you want to change to another radio station channel-search is also accessible via CV. Simply patch any gate or trigger signal into the inputs CH- and CH +. Two LEDs indicate of a trigger or gate signal is applied. Channel changes can be really quick, if there are good signals close to each other on the frequency band. If the signal is bad the search automatism may need more time to find good signals leading to slower channel changes. The RST button resets the search to the lowest frequency. After reset you will receive some really nice radio noises until you proceed to the next proper channel again. You can also route the CH- CV input to RST via jumper on the back of the PCB. The module has two volume buttons for quick level adjustments. Additionally it has an active GAIN stage adjustable via trimmer in order to raise the maximum volume to modular levels. The patch-cable connected to the OUT socket acts as an antenna. It´s best to choose a long cable and move it around until you receive the best signals. prev Up next
