AI Synthesis - Analog Voltage Controlled Oscillator
available
The AI011 Analog VCO is a robust and stable analog Eurorack VCO. Using the legendary curtis 3340 IC, the Oscillator provides buffered Triangle, Square, and Ramp waveforms, as well as a triangle to sine wave shaper to provide a sine wave output. The Eurorack VCO features both Coarse and Fine tune knobs for easy tuning. Pulse Width Modulation is normalled to the PWM input jack, so PWM is controlled with the PWM knob, and when a jack is inserted, the knob serves as an attenuator. Volt per octave and FM input jacks are present, with an attenuator for FM modulation. The VCO is capable of both hard and soft sync. An expander jack is present at the rear of the module for use with future AI modules.DIY-Kit-Type:THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. Only trough-hole parts to solder. Make sure to check the build guide before you buy.

AI Synthesis - Harmonic Mixer
available
The AI022 Harmonic CP3 Style Mixer is a discreet mixer using no ICs. As gain increases harmonics and analog warmth are added. As gain increases more, distortion and phasing is added, creating new waveforms from old ones.The AI022 takes inspiration from the legendary Moog Modular CP3 style mixer, but updates it for eurorack and allows for user customization of the circuit. Many Moog Modular users attribute the CP3 mixer module to providing much of the warmth of the Moog Modular sound.An exposed Bias knob allows abuse of the circuit, and allows for faithful replication of incoming audio, or radical analog wave shaping and distortion. It is also possible to use the Bias knob to adjust a +/- 5V signal into a 0/+ or 0/- signal.DIY-Kit-Type:THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module.

AI Synthesis - Looping ADSR Envelope Generator
only 2 left
The AI003 Looping ADSR Envelope Generator is a looping ADSR Envelope Generator. It can be manually triggered via Momentary Push Button, Gated via the Gate Signal, Triggered or re-triggered by a Trigger input, or set into a loop mode via a toggle switch. An LED shows the status of the output.This Looping ADSR Envelope Generator DIY Kit circuit was derived (with permission) from the great and simple circuit (only 2 ICs!) from Nicolas on the Electromusic.com forums. With some help from the great Dave Brown, the circuit was updated to provide additional voltage protection, more uniform looping and gate behavior, more precise LED monitoring, and some nice user experience updates.In Gate or Trigger mode, the envelope can be used as a traditional ADSR envelope generator. In loop mode, the output sends a variable exponential waveshape between Ramp, Triangle, and Sawtooth LFO with control over the attack and decay of the LFO shape.DIY-Kit-Type:THT-Kit-1.

AI Synthesis - Stomp Box Adapter
available
The AI006 Eurorack Stomp box Adapter is an updated take on a classic utility circuit that converts the higher signal levels of a modular system to be converted to the lower level signals that most stomp boxes are designed for.The AI006 stomp box adapter solves two problems.

AI Synthesis - Switching Attenuator
available
The AI010 Eurorack Attenuator is a 2 HP dual passive attenuator with switched jacks that allow the attenuator to also work as a multuple. The top-most input is normalled to the second attenuator knob and the third attenuator input. Control voltage is a wonderful way to add expression to a modular patch, and controlling that control voltage is crucial to being able to dial in that expression.A passive eurorack attenuator is a simple un-powered circuit using only resistive elements (usually a potentiometer) to reduce voltage. Rotating the potentiometer will change the output from 0V to 100% of the input without distorting the shape of the incoming voltage. These are simple and primitive, but effective and important methods of controlling voltage, be it the input to a Filter, or the Linear Frequency Modulation input on an Oscillator.DIY-Kit-Type:THT-Kit-1.
