The Percussion Interface (PI) and PI Expander are a pair of Eurorack modules that generate gates and envelopes from acoustic drums, samplers, drum machines, and virtually any audio source.Converting microphone, instrument, line and modular signals into CV and clock/gate signals, the PI and PI Expander are suited for synchronizing sequencers or other modules to the rhythm of an audio track or live percussion. The modules can simultaneously be used as a pre-amp for microphones or line-level signals, while generating inverted envelopes useful for side-chaining. The PI module contains all the core functionality and can be used without the Expander to conserve space. The Expander requires the main PI modules and adds three gain stage options, a modular-level audio output jack, a 1/4" (6.35mm) input jack, and envelope attenuation capabilities. The two modules are only sold together, they are not available separately.Features:• Sensitivity knob, Low/Medium/High gain switch, and clipping LED• Sustain control to prevent misfires, increase gate length, and control the envelope• Envelope decay control• Non-inverted and inverted envelope outputs, useful for side chaining• Four envelope outputs: two attenuated with independent attenuators, and two non-attenuated• Envelope following or generation modes• Gate output for clocking sequencers or any unit with a clock or trigger input• Compatibility with drums, pads, samplers, microphones, piezos, drum machines, etc.• 1/8" or 1/4" input jack (6.35mm)

The Sampler plays stereo or mono .wav files from an SD Card. Samples are arranged into banks by placing .wav files into folders (each folder is a bank). A maximum of 10 samplers can be loaded in a bank, and there is a maximum of 60 bank (600 samples maximum total). Sample files are limited to 4GB each, which is over 6 hours at 44k/16b/stereo.• Hundreds of samples included on microSD card• Extremely quiet, low noise and low jitter design• Stereo or Mono outputA knob and CV jack selects the Sample to play, and the Start Position knob and CV jack control where in the sample playback will begin. The Length knob and CV jack determine how much of the sample is played back: from tiny grains, to percussive hits, to longer loops... or just the entire file.Pressing Play or firing a trigger into the Play Trig jack will play the sample. Holding the Play button down for a second will toggle looping.There's also a Reverse button and jack for backwards playback, and an End Out jack for synchronizing loops, or cascading sample playback with other events.To record samples, hold Play and Reverse for two seconds. Press Play again or fire a trigger into the Play/Rec Trig jack to start and stop recording. Each recording will create a new stereo 48kHz 24bit .wav file in the current bank's folder. Recordings can be as long as your card has the capacity for: a 256GB card is 18 days of continuous recording (432.9 hours). Audio data is split into maximum 4GB wav files on the microSD card.Included with the DIY Sampler Kit:• Main PCB• Faceplate• All components required for assembly (resistors, capacitors, diodes, ICs, sockets, headers, voltage regulator, jacks, buttons, SD card slot, potentiometers, knobs)• Pre-programmed and pre-soldered "DSP Brain-Board"• 16GB micro SD card (class 10) with 4ms Sample Pack 2022• SD adaptor• 10-to-16 pin power cable• M3 screwsFeatures:• Play button/trigger jack: Tapping the button or receiving a trigger starts/re-starts the sample• Sample CV/knob: select which sample within the channel's bank• Pitch CV and Pitch knob: playback pitch (-10 to +4 octave range)• Start Pos CV/knob: position in the sample to begin playback (loop start point)• Length CV/knob: playback time (loop end point)• Length knob at max: entire file is played• Length knob 50%-99%: 200ms - 5s of the sample is played (beginning at the Start Position)• Length knob <50%: Percussive decay envelope is applied to the playback (attack-only envelope if playing Reverse)• Length <1%: Tiny grains are played (can be used to sweep through sample file data manually)• Reverse button/jack: toggles forward/backwards• Bank button: selects channel's bank• Reverse+Start Pos button/knob combo allows for setting volume of playback• Audio Inputs: 20Hz to 10kHz (+/-0.1dB); -6dB rolloff @ 20kHz / 21V peak-to-peak maximum before clipping• Audio Outputs: 0Hz (DC) to 22kHz with maximum -1.8dB difference between file data and output / +10.5V to -10.5V maximum outputDIY-Kit-Type:This is a Do-It-Yourself kit, not an assembled module.

Following our ADDAC103 T-Networks this new module is also inspired by Twin T-Networks circuits used in many legendary drum machines. A simple 4 voice module with frequency controls for each of the voices. This new module also features CV inputs with attenuverters for each voice Frequency. Due to the specificities of the circuit and to keep the module at a low price these inputs are not calibrated to 1v/octave.At each voice input there’s a gate to trigger converter so any input source is possible.Audio inputs can also be used as an input, in this case and due to the nature of the gate to trigger converter, each voice can be used as very destructive filters.The top 2 channels feature a higher frequency range, the bottom 2 channels feature a lower frequency range.Features:4 voices each with:• Frequency control with CV input and attenuverter Frequency Range Switch, Low/Mod/High• Trigger Input• Audio Output• Summing Mix output with Volume controlDIY-Kit-Type:SMD-Kit-2.

Following our ADDAC103 T-Networks this new module is inspired by its simplicity. This is a 4 voice Square Oscillator with VCA, FM switch and a slew decay for the incoming Trigger IN. All voices are then sent through a Multimode Filter.Each voice has its own VCA input where any input is accepted (Trigger, Gate, CV). The [DECAY] controls the slew decay applied to the incoming signal, if [DECAY] is fully anti-clockwise then it works as a Mute. The [FM ON] switches activate/deactivate the FM input coming from the previous voice: Voice 1 FM comes from voice 4, voice 2 FM comes from voice 1, and so on, so you can FM all of them in a FM loop.All 4 voices are summed and sent through a filter with controls over [CUTOFF] with an Attenuverter for the CV input and [RESONANCE]. Three filter outputs are provided [LOWPASS], [BANDPASS] and [HIGHPASS]The [EXTERNAL IN] input can be routed through a jumper on the back of the module allowing the incoming signal to go to:1. the filter input for processing an external audio source;2. all of the 4 voices Frequency control allowing for some experimental CV control over pitch of all 4 voices at the same time (due to the specificities of the circuit and to keep the module at a low price these inputs are not calibrated to 1v/octave).DIY-Kit-Type:SMD-Kit-2.
