op-1

This guide covers what custom firmware #250 adds to the original OP-1: tape undo and tape edits, four tapes, new synths and effects, sampler tools, an lfo, two sequencers, a scale mode, a flash check and more. Each page shows the keys to press on the OP-1 above it, and every knob and key below.

Knobs are named by colour: blue, green, white and orange (op1r's own docs call the orange one red). Pressing a knob means pushing it down like a button. "SHIFT + T1" means hold SHIFT, then press T1.

Everything else works as in te's own op-1 guide ↗. Once installed, the boot screen shows R. 00250 :). If you built your own firmware on the customize page, only the parts you picked are there.
