What ambwave does

  • Four independent tracks each pick one of eight sounds: TIDE, TEXTURE, CLOUD, WARM PLUCK, SOFT MALLET, BELL PLUCK, TIDE WARM and TIDE SILK.
  • ALGORITHM selects the track and PRESETS selects its sound, with the name shown on the screen.
  • Four knobs shape every sound: SHAPE opens the tone, MOTION adds tonal movement, DENSITY sets harmonic weight or grains, SPACE sends to delay and reverb.
  • HOME + ARP cycles HOLD, SCATTER and SEQUENCE, and HOME + SELECT sets the scatter or sequence speed.
  • Hold HOME and turn the four knobs to mix the tracks, and HOME plus the first four black keys mutes them.
  • FX + OCT\u2212 clears held notes on the selected track, and STOP releases generated notes while drones keep sounding.
  • TIDE uses a curated FM patch, TIDE WARM the analog engine, TIDE SILK the FM6 engine and CLOUD the granular engine with a bundled flute sample.
  • Scenes are made and played by hand, and the same synthesis runs in a browser version you can play without hardware.

Its modes
