What tidepool-fm1 does

  • Thirteen banks hold sixteen loops each, drones, melodies, beats and textures that always fit in time and key.
  • Scenes run from Shallows and Deep Space through Zen Garden, Night Cafe and Old Blood.
  • Every sound is synthesised live from oscillators, filters, envelopes and noise, with no samples.
  • White keys turn loops on and off, and new ones come in on the next beat.
  • KNOB 1 to 4 shape a row's four loops for Volume, Attack, Decay, Reverb, Echo or Pan.
  • Hold PLAY and turn KNOB 1 to swap the bank's chord progression for one of ninety-nine others in the same key.
  • The Blank Canvas records your own loops of 1, 2 or 4 bars on 36 instruments, including a drum kit and hand drums.
  • SAVE keeps the tempo, the bank and every loop's settings, while recorded loops save themselves straight away.
