Good to know
- Turning PRESETS loads the patch at once and goes back to CTRL: save an edit first. An edited factory patch keeps its number on screen.
- Each factory patch brings its own arpeggiator, LFO, effect settings and octave; the tempo stays yours.
- Over MIDI, a Program Change loads a factory patch; CCs out of the box: 74 cutoff, 71 emphasis, 73 / 75 attack / decay, 5 glide, 7 level, 91 reverb, 94 delay, 93 chorus.
- MONO plays like the original: one voice, the lowest key wins, GLIDE when it is on. VOICES is saved with the preset.
- Your last sound comes back at power-on (kept 10 s after you stop playing).
- Hold OCT- and OCT+ for 5 s: UBOOT update mode for reinstalling. Held while powering on: panel calibration.
A community cheat sheet by the hub, not by the firmware's makers: when in doubt, their manual is right.
