The Betweener is an affordable, open-source, DIY module (Eurorack-compatible) for use in synthesis and multi-instrument systems. It combines the flexibility of a Teensy 3.2 (programmable using the Arduino IDE) with four built-in Control Voltage (CV) inputs, four Trigger inputs, four knobs, and four CV outputs. Via USB MIDI or an add-on DIN MIDI breakout, the Betweener enables MIDI-to-CV and CV-to-MIDI conversion in a highly customizable and hackable format.
The hardware and software were developed at the School of the Art Institute of Chicago for use in the Sound Department course Selected Topics: Analog/Digital.
For example, the Betweener can be used to:
Translate MIDI CC signals (e.g. from a foot pedal) into CV outputs from 0 to 5 volts
Use external triggers to trigger custom-programmed MIDI note sequences
Take input from a variety of Teensy-compatible external sensors (e.g. motion sensors, light sensors, etc.) and convert information into MIDI or CV outputs
Use programmable knobs to modulate any CV-controlled or MIDI-controlled instrument
Easily communicate between modular synthesizers and digital audio workstations such as Ableton Live and Reaper
