Good to know

  • Keys play notes on tracks 1-3; on track 4 (drums) the white keys are 16 drum sounds.
  • Every function button is a layer: hold it and the keys and knobs change job.
  • Autosave: stop and leave it 2.5 s; it comes back as you left it at power-on.
  • A short tap of FX, SEL, EDIT, GLO, ARP, SEQ or SAVE opens its pages instead.
  • The REC screen (REC while stopped): KNOB 1 free / tempo, KNOB 2 bars, KNOB 3 count-in.
  • Everything is played live: there are no factory patterns.

A community cheat sheet by the hub, not by the firmware's makers: when in doubt, their manual is right.
