4ms - Percussion Interface & Expander

Product information "4ms - Percussion Interface & Expander"
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.

• 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)

Manufacturer "4ms"
In 1996, Dan Green founded an innovative effect pedal business named 3ms Pedals near Chicago, Illinois, USA. The unique designs features many knobs and the option for custom artwork and modifications. Two years later Dan moved to St. Louis, Missouri, and began producing table-top noise devices as well as effect pedals for experimental musicians. In 2002, the business changed its name to 4ms Company (d/b/a 4ms Pedals) and only a few years later began creating an advanced digital meta-instrument: the Bend Matrix, a 4x8 dynamic routing matrix, automatic circuit-bender, and octophonic mixer. In 2009, the company moved to Austin, Texas, and began designing Eurorack modules. In 2012 we moved to beautiful Portland, Oregon, where we currently have our studio in the west coast nexus of synthesizer makers. In 2016 and again in 2017 we won Electronic Musician's Module of the Year!
