What gnomad-firmware does

  • Turn ALGORITHM to choose one of ten pictures, from the Gnome to organ, bells, whale and drums, holding 57 sounds.
  • Turn PRESETS to pick a sound inside a picture, and MASTER sets the volume.
  • Four coloured knobs, blue, green, yellow and vermilion, shape each sound, with the screen naming every knob's job.
  • Press REC then PLAY for a 4-3-2-1 count-in and record a loop that goes round and round.
  • Four tracks let four sounds play at once, chosen with FX, SCL, ENV and LFO.
  • Press SEQ twice for STEPS, where white keys place hits and holding a key with the knobs edits one hit.
  • Hold PLAY to restart on the bar, GLO + PLAY to stop at the bar end, hold GLO for fills and hold FX to audition.
  • Tap SAVE or stop and wait four seconds to save, hold SAVE to undo, and connect over USB and TRS MIDI.
