PassOS
Firmware for Octatrack MKI / MKII (Elektron)
Octatrack MK1 mod with 36 Digitone II scales across twelve roots on MIDI tracks and a STOP guard, on top of stock OS 1.40C. Nothing is placed on the DSP, so stock FX are untouched.

Description
MIDI NOTE SETUP's two empty cells become SCL and ROT, using the Digitone II's thirty-six scales in Appendix E order. Built on octabam, whose README is kept alongside. The project states that no built image is ever distributed.
Install notes
Build from your own OS 1.40C using octabam's toolchain; PassOS 1.0 runs on the author's hardware.
