3D printed audio mixer for controlling PC audio volume. Allows control of 5 or more programs simultaneously.
Designed to interface with deej, an open-source audio control program for Windows and Linux. For more info on the deej project, check out their work here: deej github.
New iterations also work with MIDI, a standard protocol in music production. My custom firmware supports both deej and MIDI simultaneously!
