The Arpeggio sequencer distributes notes from a held chord across time, creating arpeggiated patterns automatically.

Basic Operation

Press SHIFT + Sequencer key (dots icon), turn the blue encoder to select Arpeggio, then press Sequencer key to confirm. Hold multiple keys on the keyboard to create a chord. The sequencer plays the notes in sequence.

Main Parameters

  • Blue encoder: Time signature (sets rhythm division)
  • Green encoder: Trigger mode (none/once/each/all/trig - controls when arpeggiation starts)
  • White encoder: Pattern dots (selects which steps play)
  • Orange encoder: Turn fully to HOLD for continuous playback

Advanced Settings (SHIFT + encoder)

  • SHIFT + Blue: Note length in ticks (1-64)
  • SHIFT + Green: Arpeggio type (octave up, up and down, intervals)
  • SHIFT + White: Pause/skip toggle for pattern variations
  • SHIFT + Orange: Swing amount

Playing Tips

Hold down different combinations of keys to change the chord being arpeggiated. The pattern automatically adapts to however many notes you hold. Release keys to stop the arpeggio, or use the orange encoder's HOLD function to keep it running without holding keys.
