PieJam

PieJam is a flexible, touchscreen-first audio mixer for Linux.

It was designed specifically for the 7″ Raspberry Pi touchscreen, with the goal of running as a standalone mixer on a Raspberry Pi paired with a USB audio interface. While this is the primary target, PieJam is not limited to the Raspberry Pi and can run on other Linux systems as well.

PieJam supports dynamic audio routing, per-channel processing, MIDI control, and session recording, making it suitable for live performance, rehearsal setups, and embedded audio systems.

For building a complete Raspberry Pi–based system image, see the accompanying PieJam OS repository.
