What CoralFlower does

  • Press a chord key and every note you play becomes a full chord with a bass underneath.
  • Choose major, minor, sus2, sus4 and major and minor 6, 7 and add9, and press two chord keys together to combine them.
  • Around 60 sounds come from two engines, virtual analogue and FM, with separate lists for chords and basses and slowly moving pads.
  • Two key layouts, Top and Side, each with a Lock mode that keeps a chord type after you tap it.
  • The sequencer holds eight patterns of chords, bass, drums and a layer track, plus a song made from them.
  • REC on the main screen records your playing into a new pattern after a one-bar count-in.
  • Twenty-three ready-made rhythms in several time signatures play under your chords, with six new kits including X Lo-Fi and X Tech.
  • Six effects run in an order you choose: filter, drive, chorus, phaser, delay and reverb.
