BMC030 Instrument Interface

Connect external audio sources to modulate, generate gates, envelopes and more

This is actually the BMC030 Guitar Input module from Barton Musical Circuits built by Lower West Side Studio. Because the interface can accept so much more than just guitar input we decided to re-brand it the Instrument Interface.

Just about any audio source can be processed through your modular with the help of this handy utility module. Gates are generated which can then be used to trigger events such as sequencer steps. The module even features its own envelope generator!

A Gain control and input level switch allow you to control the incoming signal and get it just to the level you want it at to distribute through your system. Potentiometers allow you to adjust the levels at which gates are triggered by your input and how long the envelope triggered by the gate remains active.

Outputs Included;

Audio Output – This is the amplified audio sent into the external input.
Envelope Output – This is a rectified and filtered version of the audio, useful as control voltage.
Gate Output – This is a +5V/0V pulse, useful for triggering things like A/R generators
Square Output – This is a +/-5V audio pulse output.

The module operates at +/- 15V and comes with a Synthesizers.com style power connector.
