Features:Flexible input/output layoutThe module detects the presence of jacks on its gate inputs to group its segments: whether it is configured as a complex 6-stage envelope, or 6 individual envelopes, or 3+3, 2+4... depends simply on how you patch it. Dummy patch cables might come handy!When used as a multi-segment envelope, a segment activation signal is produced on all secondary outputs - for example to trigger an external event when an ADSR envelope enters its decay, sustain or release stages.In case more than 6 segments are required, up to six modules can be chained together thanks to a connector at the back of the module.Three segment types• Ramp segments go from one voltage to another, in a CV-controlled amount of time, with an adjustable curve (accelerating, uniform, decelerating). They are the building block used for the attack, decay or release segments in envelopes... or for LFOs.• Hold segments stay at a constant (but CV-controllable) voltage for a programmable amount of time. They serve as the sustain or hold segments in envelopes.• Step segments glide to a target (CV-controllable) voltage, then stay at this voltage for a certain amount of time until a trigger is received. They are the main ingredient for step sequences, but also for building sequential switches or a sample-and-hold.LoopingA segment, or a group of segments, can loop on itself: if the last segment of the envelope is included in the loop, the loop lasts forever. Otherwise, the loop remains active while the gate is high, then continues past the last segment of the loop. These two behaviors allow the creation of self-looping envelopes (LFOs), or the sustain stage of a good old ADSR envelope!Single segment processingEven when they aren't part of any group and don't receive any gate or trigger signals, individual segments can perform interesting functions: Ramp can loop on itself and turn into an LFO, Hold can delay a CV and Step can slew it.Now patch a trigger signal: the self-looping Ramp turns into a tempo-synced LFO, the Hold segment becomes a pulse generator, the Step segment a sample-and-hold.DIY-Kit-Type:PCB only Kit.

The AI001 Multiple Eurorack Synthesizer Module is a 1x6 or a 2x3 passive multiple in only 2hp! It is critically important to be able to split and distribute your modular's signals to multiple destinations with the AI001 Multiple Eurorack Synthesizer Module. Because the module takes up only 2HP, they can be placed anywhere.The Multiple Eurorack Synthesizer Module can be used as either a 2x3 passive multiple, or a 1x6. The first set of four are linked together, and if nothing is plugged into the 5th jack, then that signal continues to the 6th, 7th, and 8th as well. If a cable is plugged into the 5th jack, then those signals are distributed to the 6th, 7th, and 8th jacks and it functions as a 2x4 multiple.DIY-Kit-Type:THT-Kit-1.

The AI106 West Coast Mixer is a fully discrete mixer design that updates vintage West Coast synthesizer mixer designs into a modern form.The AI106 West Coast Mixer takes inspiration from vintage mixer circuits from 60s and 70s West Coast synthesizers, but updates it for eurorack and allows for user customization of the circuit. True to original circuits, the output is inverted. Audio rate signals will sound about the same, but cv signals will be inverted.Because "West Coast" Synthesis focused more on waveshaping and Complex VCO structures as opposed to Subrtacting frequencies from simple waveforms (East Coast), mixers are an important part of traditional West Coast synthesis techniques.DIY-Kit-Type:THT-Kit-1.

Muxlicer is a sequential signal processor designed for add a huge range of special functions to your modular setup in the minimum space.Is divided in three main blocks: a Digital Step Controller, a Gate Generator and an Analog Switch (a.k.a. Mux/DeMux)The module is designed with high “function to HP ratio” philosophy , to have maximum flexibility in minimum space.An analog switch is a device capable of switching or routing analog signals. In the case of Muxlicer, the switch is reversible, so you can send 8 different signals to 1 destination and viceversa.Through Common I/O you can either send a signal to the Mux I/Os or receive a signal from them. (Depending on how the module is connected). It is also used as CV Out when nothing is connected to “All In” or “Mux I/Os”. The eight Mux I/Os are normalled to “All In” jack, so any signal present at this input will go to all of them.Imagine you want to send a signal to steps 1,2,4,5,6 and 8 and two more signals to 3 and 7 respectively. You just need three wires for this: plug the first one to All In and the other two to 3 and 7 Mux I/Os and you are done!Features:• Route any modular signal from one IN up to eight different Outs or vice versa.• Generate CV and Gate signals, been able to work as sequential voltage source a.k.a. sequencer.• Cut audio signals in rhythmical slices with independent volume.• Generate complex and dynamic patterns from any audio or modulation signal.• Create powerful Gate sequences with control voltage retriggering for each step.• Select easily when your signals act on your patch with the Address function.DIY-Kit-Type:THT-Kit-1.

Power your pedals directly from your Eurorackcase with Pedal POW – a compact dual power supply that delivers two isolated 9 V outputs, each capable of supplying up to 500 mA to run your stompboxes reliably on stage or in the studio.Pedal POW converts your Eurorack +12 V rail to clean 9 V pedal power while sharing the available energy with your modular synth. Because Pedal POW depends on your Eurorack power supply, its total available power cannot exceed what your Eurorack PSU can provide. Make sure your Eurorack power supply has enough headroom to run all installed modules plus anything you connect to Pedal POW.Each Pedal POW output can supply a maximum of 500 mA. Keep in mind the conversion draw: every 1 mA delivered by Pedal POW draws approximately 0.8 mA from the +12 V rail. For example, to deliver the full 500 mA on one output you must provide 500 mA × 0.8 = 400 mA from the +12 V rail. If both outputs are used at their maximum, the pedals would draw 500 mA + 500 mA = 1000 mA, which corresponds to 1000 mA × 0.8 = 800 mA from your +12 V bus.Before connecting multiple high-current pedals, verify your Eurorack power budget and factor in the Pedal POW conversion rate. Use the product’s reference table or this conversion rule (1 mA at Pedal POW ≈ 0.8 mA from +12 V) to quickly calculate how much current you need from your Eurorack supply so you can avoid overloading the system and keep your rig stable.Features:• 1U Intellijel format• Dual power supply with two isolated outputs, each providing 500 mA• Center negative (-) polarityDIY-Kit-Type:SMD-Kit-1.
