Good to know

  • Tracker basics: each row is one step, played top to bottom; each lane is one part.
  • Quick beat: SELECT to CH6, KNOB 1 to row 00, press F3 (kick), turn KNOB 1 three rows down, repeat, then PLAY.
  • Each key press writes a note and steps down, so you can type a melody row by row.
  • INST picks one of four shared synth instruments; CH1-CH4 start on 1-4, CH5 on 1.
  • The very first save formats the storage and wipes old ETCH/Felucca data: back up first.
  • Hold SEQ and tap ENV (stopped) for groove: microtiming, ratchets and chance per step.
  • On-device help: HOME, KNOB 1 down to HELP, SEL.

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