What LOOM-8 does

  • Eight tracks play ten engines: six synths, a sample player, a break slicer, a drum kit and MIDI out.
  • A 64-step sequencer gives each track eight patterns, fifteen step tricks, parameter locks and up to four notes per step.
  • Weave crosses two patterns live: bar by bar, step by step, or one's rhythm with the other's pitch.
  • The conductor moves every following track through a key, scale and chord progression you play or sequence.
  • Throws fire momentary mute, stutter, repeat, echo, build, floor and jumble effects from the keys while it plays.
  • Thirty-two scenes, a song chain, a mixer, two send effects and a master with EQ, compressor and pump.
  • It saves by itself when stopped, and MIDI arrives over USB, Bluetooth and the TRS jack.

Its modes

Arrange
See every track's pattern and playhead, switch scenes on the white keys, mute tracks on the black keys and set the tempo and groove.
Song
Chain scenes into slots and set how many bars each one plays, looping or stopping at the end.
Steps
Write notes, chords and drum sounds onto the sixteen cells of a bar, and hold a step for its velocity, length, chance, pitch, tricks and locks.
Bar
Set quantise, new note length, groove and shape, and jump to or loop the pattern's bars.
Engine
Pick the track's engine and preset and turn its four sound knobs.
Envelope
Shape the amp envelope, and on a drum track the attack, hold, decay and lag of each key.
Character
Give the track its own drive, fold, crush, ring, tilt, tape or sampler colour.
Players
Choose how the keys play the track: arp, strum or hold, with their own settings.
Weave
Cross the track's pattern with another track's pattern by bars, steps, rhythm or pitch.
Mix
Set each track's sends, pan and level, mute or solo tracks, and reach the master and Setup pages.
