Description

A derivative of FoMni. Keys play one-shot samples; REC records and overdubs one pattern that is kept in RAM only and lost at power-off. Tempo, reverb and delay have knobs, and MIDI channel 1 notes 53-79 play the keys. The author reports the eleven recordings come from Pixabay and says their individual redistribution terms are not independently verified.

Install notes

Download fart-machine-one.fwsc and the source zip from the release, then run tools/fm1_install.py (Python 3 with mido and python-rtmidi). Installation replaces the current firmware. If an update is interrupted, run the same command again.
