4ms Percussion Interface (PI) & Expander - Teaser

4ms Company

Note the Percussion Interface made its first appearance at SUPERBOOTH 2019 and 2020.

"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 module and adds three gain stage options, a modular-level audio output jack, a 1/4” (6.35mm) input jack, and envelope attenuation capabilities.


Percussion Interface and PI Expander 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, samplers, microphones, drum machines, etc.

1/4" input jack (6.35mm)

4HP each
