Mixer & VCA cuerly / 3-channel stereo mixer with cue / 6 HP ⇣ Cuerly is a compact 3-channel stereo mixer with cue functionality, allowing you to pre-listen to signals before sending them to the main mix. It’s the perfect mixer for live performances in a small Eurorack setup. 1/4 key features 3 Stereo-Channels Level Control per Channel Cue Buttons for Pre-Listening Heaphone Output Headphone Level Control Mix to Headphone Control Max. Gain +20dB Wrong polarity protection specs & downloads width: 6 HP depth: 40 mm power: 43 mA @ +12V / 35 mA @ -12V documentation videos description / manual Cuerly features three stereo channels, each with independent level control. You can connect a stereo signal to any of the three inputs: IN1, IN2, or IN3. The level of each channel is adjusted using the corresponding VOL1, VOL2, and VOL3 knobs. Mono signals can also be processed by patching a cable into the left input, which will automatically normalize the signal to the right channel. The final mix is sent to stereo headphones via the TRS PHONES output. You can control the headphone volume using the VOL HP potentiometer. To preview a signal, simply press the corresponding cue button. The cued signal is removed from the main mix and routed exclusively to the headphone output. The VOL1, VOL2, and VOL3 knobs continue to function as level controls, even when the signal is cued through the headphones. The LEDs serve as level indicators for the cued signal only. For direct comparison, turn the MIX TO HP knob to the right. This routes the main mix to the headphones along with the cued signal, allowing you to compose and patch new sounds while still monitoring the main output - without needing to remove your headphones. You can cue any combination of the three channels. If all three cue buttons are active, no audio will be sent to the main output, and the signal will be routed only to the headphones. Additionally, the cue buttons can function as mute controls for the main mix. Cuerly offers a maximum gain of +20dB, with independent gain adjustment for each of the six inputs. Gain levels can be fine-tuned using the trimmer potentiometers located on the back of the module. Cuerly is designed specifically for live performances, where sounds are improvised and created on the fly. Its compact size makes it the ideal addition to your small performance case.

Meet the Swiss Army knife's ambitious cousin – the multitasking marvel that sits in front of your Eurorack, ready to unscrew musical conundrums, slice through soundscapes, and twea-zor its way into your sonic heart. workbench / usb powered multi utility tool / 0 HP ⇣ Meet the Swiss Army knife's ambitious cousin – the multitasking marvel that sits in front of your Eurorack, ready to unscrew musical conundrums, slice through soundscapes, and twea-zor its way into your sonic heart. key features Multiple LFO Attenuator documents Fader Swap USB-Power description / manual Multiple 1 to 3 multiple with one inverted output. The multiple is normalised to the swap unit of the module. LFO The LFO provides a triangle and square wave and can be reset by an external gate or clock signal. The LFO signal can be attenuated with the slider pot and its rate may be varied with the RATE potentiometer. An inverted copy of the triangle wave is normalised to channel A1. An inverted copy of the square wave is normalised to channel B1. These connections are independent from the LFO attenuator and may be interrupted by patching a cable into the channel A1 or B1 input or by the normalisation selection switches. You can choose to normalise the LFO or a fixed voltage of 0V to +5V adjustable with the VOLTAGE knob for all channels at once. Attenuator/Mixer WORKBENCH has four channels A1, A2 and B1 and B2. Any signal (audio or CV) patched into the inputs are attenuated by the slider pots. The channels of each section are daisy-chained, thus they can be mixed or the second channel can act as an offset (CV). The normalisation switch selects which voltage will be fed into the input if no cable is being patched (LFO or fixed voltage 0V to +5V). Fader The Fader mixes between two sources with a single slider. Both channel sections A and B are mixed into a fader circuit, if no cable is inserted into their outputs and the fader inputs. The fader output can be attenuated with the LVL knob. Swap The Swap unit exchanges the destination of one or two sources with the push of a button. This way you can route two signals to the corresponding destination of the other input. Anything patched into the Mult will also be multiplied to the Swap inputs of nothing is patched here. USB Power WORKBENCH is powered by standard USB power (+5V) and is fully compatible with your Eurorack system. You can choose to power it with a Mini B, Micro B or Type C USB cable. You can solder all USB connect or just one of them, if you have a favourite USB cable you want to use. Up

It has a mono INPUT with a LEVEL attenuator and any signal fed in is sent directly to the stereo outputs OUT L and OUT R. If you turn SEND A to the right, you can adjust the portion of the signal that is sent to the SEND A output.This can then be fed into an external effect and returned in mono or stereo to the upper RETURN (L) and RETURN (R) inputs. The TONE potentiometer accentuates either low (turn to the left) or high frequencies (turn to the right) of the signal routed to the send output. Leave it in the centre position so that the frequencies are not affected. The same applies to SEND B, the lower inputs RETURN (L) and RETURN (R) and the corresponding potentiometers SEND B and TONE. Both send s can be used simultaneously. Two LEDs indicate if a signal is sent to the send output. Gain trimmers are located on the front panel to adjust the gain of the send signal. prev Up next

Oscillator radio / analog fm radio with autoamtic cv channel search / 4 HP ⇣ RADIO is an analog FM RADIO with an automatic channel-search functionality. It supports a frequency band of 83,5 - 114 MHz, has a built-in frequency control with signal quality evaluation and runs with automatic noise suppression. It is a never ending sound source and a great companion for your Eurorack sampler or audio mangler. 1/3 key features Analog FM Radio Automatic Channel Search with Signal Quality Evaluation Automatic Noise Suppression 83,5 - 114 MHz Bandwidth CV Control over Channel Search or Reset Volume Control Gain Stage at the Output Illuminated ST Modular Logo specs & downloads width: 4 HP depth: 28 mm power: 18 mA @ +12V / 10 mA @ -12V documentation videos description / manual By pressing the buttons CH- and CH+ you can activate the automatic channel-search function up or down the frequency range. 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

The outputs are protected against unwanted phantom power voltages. There are also PCB outputs available if you want to solder case/cabin mounted output jacks directly to the UIT PCB. UIT is supposed to be the last module in your modular chain and connects the modular world with any other studio or stage input equipment. prev Up next

WORKMATES is a series of little passive 0HP modules that offer simple but effective audio and CV processing in conjunction with your modular or semi-modular synth. Note that these are passive modules without any power consumption. As a result, you will have a bit of signal level reduction when patching a WORKMATE within your modular processing chain. Nevertheless these little helpers are very convenient solution providers if you run out of HP. workmates / passive eurorack tools / 0 HP ⇣ WORKMATES is a series of little passive 0HP modules that offer simple but effective audio and CV processing in conjunction with your modular or semi-modular synth. Note that these are passive modules without any power consumption. As a result, you will have a bit of signal level reduction when patching a WORKMATE within your modular processing chain. Nevertheless these little helpers are very convenient solution providers if you run out of HP. They are also the easiest way to learn SMD soldering. Practice your soldering skills without any fear of shorts and magic smoke. passat PASSAT is a fully passive 4-channel attenuator featuring four smooth sliders for intuitive level control. Each input has its own dedicated slider, allowing you to reduce the signal level by moving the slider downward. At the lowest position, no signal is sent to the output. At the highest position, the input signal is passed through unchanged. Input 1 is internally normalized to inputs 2–4. If no cable is connected to inputs 2–4, the signal from input 1 is automatically routed to those channels. This allows PASSAT to act as a simple passive signal multiple with individual attenuation per channel. As a completely passive design, PASSAT requires no power and does not consume any of your precious case HP. It is an ideal utility for controlling multiple audio or CV sources from a single point. Use PASSAT to attenuate Eurorack audio signals to line level, mix multiple CV sources, or precisely scale control voltages for sensitive module inputs. pix PIX is a passive mixer with 3 stereo inputs and 1 stereo output. Each channel has its own volume control and tilt EQ. With the EQ you can emphasize either low or high frequencies. Due to its passive design, a very compact format could be realized, with dimensions of only 55mm x 65mm. It was designed for use with modular level inputs, which are further processed by line-level devices with volume amplification. You can also use this mixer with line-level synthesizers, but you will lose quite a bit of volume. If too much gain is then used in the downstream processing chain, the noise floor can be raised to an uncomfortable level. Nevertheless, PIX has been used successfully with line-level signals. It has an input impedance of around 1.2kΩ at 1kHz. PIX is your solution for compact mixing requirements in a mobile modular setup. split Splits MIC MONO INPUT and STEREO OUTPUT signals to individual jacks from TRRS Combo Jack. The microphone input has a level potentiometer. Ideal for easy sampling and mixing with devices like OP-Z or tablets. touch TOUCH is a passive, touch-sensitive attenuator. Any signal applied to the input jack passes through your skin to the output jack. Depending on the amount of pressure and the moisture of your finger, the resistance decreases, allowing a larger portion of the signal to pass through. trs switch TRS MIDI type A to/from TRS MIDI type B adapter. Swaps the tip and ring of a 3.5mm stereo jack. Ideal for connecting TRS MIDI devices with different TRS MIDI standards (e.g. Novation device with KORG device). lpg LPG is a passive vactrol based low pass gate. It also has a passive low pass filter for subtle tone control. By choosing different kind of vactrols you will achieve contrasting kind of gate responses, from lush and slow to very fast and snappy. clipping cat CLIPPING CAT is a passive distortion that can blend between hard clipping crossover distortion and softened LED clipping that is only applied to negative peaks of the signal. Hence you can control the type of distortion from harsh clipping to a rather subtle distortion with more even order harmonics. “Clipping Cat” will wink if you turn the potentiometer counter-clockwise for softened distortion and will stare at you with both eyes turning it clockwise for harsh clipping. Clipping Cat is also availbable as an active 3U module! swap SWAP exchanges the destination of one or two sources (audio or CV) with the push of a button. This way you can route two different signals to the corresponding destination of the other input or route one signal to either one of two patch cables. You may also use it as a simple on/off switch. There might be audible clicks when using it to swap/switch audio. combiner COMBINER is either a 4 to 1 Passive Mixer, an or-wired Trigger/Gate Combiner or a 1 to 4 Passive Mult. Before soldering you have to decide which functionality you prefer. If you solder resistors you will get a four-channel mixer and if you solder diodes you will have a trigger/gate combiner. For a Passive Mult you just need to short the pads mentioned in the BOM. eq EQ is a one knob low and high frequency EQ with mid frequency range control. Turning the knob counter-clockwise will filter out frequencies above 1kHz and turning it clockwise will filter out frequencies below 1kHz. Not filtered frequencies are emphasized a bit to have a sharper sound when lower frequencies are filtered and to have more bass when higher frequencies are filtered. The little mid frequency range knob moves the cutoff range around 1kHz and changes how much the not filtered frequencies are emphasized. attenuator ATT is a simple attenuator that allows level control over CV or audio signals. If you want to use it for audio and you don´t have a logarithmic pot at hand, you have the option to use a linear potentiometer and solder an additional resistor for a fake logarithmic response. videos Up

The envelope may be re-triggered using the RTRG input as long as the Gate on the Gate Input is high. ADSR has three different Length Modes from Slow over Moderate to Fast. The envelope can be very short (20uS) up to very long (110s) making it a useful tool for percussion like sounds and evolving soundscapes. The Moderate Mode is the best option for regular synth sounds. The LED between the A (Attack) and D (Decay) potentiometer indicates the current state of the envelope. prev Up next

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!
