The full story
OP-1 Mods 1.0 adds the KEYS electric-piano engine, TRACK sequencer, six effects and the TIDE LFO to the original OP-1. Its author says the C code was developed with substantial help from Claude and tested in an emulator and on real OP-1 hardware.
The release is a patch for the owner's official firmware 246, with installation code and a manual rather than the manufacturer's firmware. The author documents how sounds using the new modules can prevent stock firmware from booting until those sounds are changed back.
