Firmware risk: Unofficial firmware for the original OP-1. Back up tapes and sounds first, and flash the official 246 update to go back. Early community builds have left units stuck on an error screen at start-up.SourceSource
About
A custom firmware for the original OP-1, built in the browser: you tick the features you want and the page generates the update file. Release #250 adds tape undo/redo (up to seven steps that survive power-off), live tape edits (merge drops, copy and paste the loop while playing, bounce all tracks), four independent tapes, fit-to-bars sampling with zoom and retune, deleting and renaming sounds, crush, warble and plate effects, a scale mode and a flash-storage check. It also includes op1r's synths, effects, LFO and sequencers. A step-by-step guide shows the key combos for every feature.
