What Loom FM-1 does

  • Fourteen engines cover virtual analog, six-operator FM, wavetable, granular, slicing, multisample, physical modelling, formant, organ, chiptune, noise and drums.
  • Five tracks play at once: four polyphonic synth or sampler parts plus a drum track with choke groups.
  • Each track holds a 64-step sequencer with chords, ties, accent, slide, chance, velocity, ratchets and parameter locks.
  • Record live with overdub, step record at the cursor, or reshape patterns with SEQ TOOLS like RANDOM and COOK.
  • Chord keys, a chord progression generator and a ten-mode arpeggiator turn one finger into full voicings.
  • Hold FX for repeat, reverse, filter sweeps, tape stop, freeze, harmonizer, flanger, phaser and reverb or delay throws.
  • Save sounds to 32 user slots and four projects, chain them in SONG, and power on where you left off.
  • USB carries class-compliant MIDI and stereo audio to a computer, with TRS MIDI in and a browser editor for patches and samples.
