What NOIZ DEMONS does

  • Hold EDIT and press the SUM key to reroll the track's sound, with one of thirty demons deciding how far it moves.
  • Each demon has a rank and a power from 15% for Furcas up to 100% for Belial, who can land any value anywhere.
  • Summoning from HOME rerolls the FM6 patch, ENV, LFO and FX together, while an operator page rerolls the whole FM6 patch.
  • Turning a knob on an ENV, LFO, FX or operator page summons too, a new demon on every click.
  • Hold SAVE to undo back to the sound you had before you started summoning.
  • The demon's sigil replaces the graph area on every page, showing its name and rank and breathing with your sound.
  • Summoned sounds save with presets and projects, and record as automation when you summon while armed and playing.
  • On FM6 a summoning never comes out silent, and the keys always keep playing pitched notes.

Its modes

Ritual
Hold EDIT and press the RIT key to let demons into the track, so knobs and the SUM key summon new sounds.
HOME
Summon everything on the track at once: the FM6 patch, ENV, LFO and FX under one demon.
OPERATOR
Summon the whole FM6 patch, including all six operators, algorithm and feedback.
OPERATOR 2
Another operator page where a summoning rerolls the entire FM6 patch.
OP ENV
Set the operator envelopes that FM6 actually uses, and summon the full patch from here.
ENV
Summon the whole envelope area across every page of that family.
LFO
Summon all LFO pages together under one demon.
FX
Summon the whole effects area for the track.
DLY
Adjust the shared delay, where a summoning rolls only this page and SAVE cannot undo it.
REVERB
Adjust the shared reverb, summoned one page at a time for every track at once.
