Mixer & VCA mia / 2x2 channel mixer with fader / 5 HP & 28 HP ⇣ MIA is a fairly simple, but very handy 2x2 channel mixer with an optional fader output. 1/6 key features 2x2 Channel Mixer Volume Control for each Channel 2 Channel Fader Fader Volume Wrong polarity protection Skiff friendly specs & downloads width: 5 HP & 28 HP depth: 25 mm power: 35 mA @ +12V / 25 mA @ -12V documentation videos description / manual CH1 & CH2 have two input jacks with VOLUME control potentiometers each. The signals inserted here will be mixed and supplied at the CH1 & CH2 outputs. Simultaneously the signal will be routed to the FADER. The summed signal of channel CH1 & CH2 will be available at the FADE output. Using the Fade potentiometer you may mix the two channels to taste. The overall FADE volume may be adjusted using the FADE VOL potentiometer.If there is a cable plugged into the IN A or IN B jack, the connection of the mixer channels to the FADER is interrupted. Thus you can mix 4 sound sources and fade two additional signals at the same time. Originally this mixer was designed to mix several VCO waveforms with the ability to route each of the mixed signal (from CH1 OUT & CH2 OUT) to external modules, such as effects and filters, and then again mix the externally proccessed signals (using IN A & IN B) to one single output (FADE out) via the fade circuitry. In some cases it might even serve as a stereo mixer. This module is available in 3U and 1U! prev Up next

For each output A-C you can decide whether the signals should be processed unipolar or bipolar. The LEDs indicate whether a positive or negative signal is present at the respective input. They only show input signals, as it is so much easier to identify a signal to be mixed with other signals. There is also a sum output with LEDs that provides a mix of all outputs. prev Up next

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

Mixer & VCA mix & pan / 4-channel mixer with vca, cv pan, and cv scan. / 18 HP ⇣ This module is great for creating ever-changing and organic soundscapes throughout the complete stereo field, making your composition a very varied and a persistently interesting listening experience. 1/4 key features 4-Channel Mixer 4x VCA 4x CV PAN CV SCAN CV SPAN Volume Slide Pots Wrong Polarity Protection specs & downloads width: 18 HP depth: 55 mm power: 92 mA @ +12V / 78 mA @ -12V documentation videos description / manual MIX & PAN completes the ST Modular SUM mixer series with a fully CV-controlled 4-channel mixer. It features CV PAN, VCA per channel and a CV CHANNEL SCANNER. Each channel has a VOLUME SLIDER and a VOL CV input to control the internal VCA. The panning per channelcan be adjusted with the PAN controls or the PAN CV inputs. LEDs indicate the channel volume and the stateof the panning. All channels are sum med and can be tapped at the main output jack. The SCAN and SPAN functions are really the most outstanding features of the module. They provide a unique way to mix 1 to 4 channels using one or two CV signals applied to the SCAN and/or SPAN CV inputs. The scan functionality allows you to output a selection of channels by turning the SCAN knob or applying CV to the SCAN input. The range of channels that are activated is set manually or by CV using the SPAN knob. This not only narrows down the active channels from all to just one, but also reduces the effect the SCAN CV hason the VCAs, as if you were shortening their decay time. When both SCAN and PAN are in the centre position and you turn SCAN, you activate one of the four channels at a time. If you increase SPAN, more of the adjacent channels become audible until all channels have reached maximum volume (from mid to cw position). If you decrease SPAN again, only one scanned channel will be audible (mid position) and it will then start to fade out shorter (turning from mid to ccw position). If a CV signal is present at the SCAN CV input and you turn SCAN to the left, the activated channels are narrowed to the left. Conversely, if you turn the knob to the right, only channels 3 and 4 are activated, and in the rightmost position, only channel 4. All CV inputs also accept audio signals, and it is quite interesting to control them with CVs that transition seamlessly from low frequencies to audio rates.

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.

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

These channels are interconnected through flying bus cables and standard ribbon cables at the rear, allowing expansion from a minimum of two channels to suit your requirements and available HP. STEREO SUM is a true performance mixer aiming to be used in live situations. key features Stereo Mixer Customizable Amount of Stereo & Mono Channels EQ per Channel Two Send/Returns AFL Mode to Audit Sounds Mute Switch per Channel +20dB Gain per Channel Stereo Input to Integrate other Mixers Stereo Line Output Mix to Headphone Knob for Sound Comparison Skiff Friendly Wrong Polarity Protection specs & downloads width: min. 12 HP depth: 30 mm power: min. 47 mA @ +12V / 33 mA @ -12V documents videos layout suggestions description / manual STEREO SUM is a stereo mixer with a customizable amount of stereo or mono channels. Tailor your setup by selecting the desired quantity of SUM CHANNELS or MONO CHANNELS to integrate with the SUM MAIN module. Each STEREO or MONO CHANNEL has a mute switch, a one knob EQ, Pan, a Send knob that can be routed to two different destinations, a Level pot and an AFL (after fade listening) functionality, which allows you to audit your sounds on the headphones before you add them to the mix (pre Pan though). 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). The SUM MAIN module has all output, send and return jacks, a master volume knob and a 6.3mm stereo headphone jack with a dedicated volume potentiomter. The Mix to AFL 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 (AFL mode). Additionally there is a stereo input to integrade other mixers, like PHOEBE, SUM or uSUM for example. All stereo inputs can also handle mono signals. If you want to save HP it might be a good decision to add some MONO CHANNELs to your STEREO SUM. 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 channel has two separate GAIN trimmer potentiometers adjustable from the front. For enhanced EQ control of your mix, consider integrating the STEREO EQ . Additionally, you can enhance each channel or the main output with the STEREO COMPRESSOR . TO ENSURE THE MIXER'S FUNCTIONALITY, IT'S CRUCIAL TO HAVE AT LEAST ONE STEREO OR MONO CHANNEL, IN ADDITION TO YOUR MAIN MODULE. Up
