MIN-1

A self-playing minimalist ensemble after Philip Glass: it starts on power-up, and you take over with chords, processes on the figures and song recording.

What MIN-1 does

  • MIN-1 plays itself from switch-on, so there is always a repeating figure and slow chord cycle running.
  • Four models shape the music: ARPEGGIO, PHASE, PATTERNS and BELLS, with twenty pieces to choose from PRESETS.
  • Press white keys to play the harmony: in EASY every key is a chord that fits, black keys add a seventh.
  • EDIT rolls a new idea for the current page, a chord cycle, figure, melody, bass or rhythm, and SEL + EDIT goes back.
  • Hold SEL and ENV, ARP, LFO, SEQ or FX brings a part in or out at the next chord.
  • Hold SEL and press white keys 1 to 8 to grow, shrink, shift, flip, still, slow, speed or start a new section.
  • SEL + REC learns a cycle from two to eight chords you play, keeping it as Mine.
