Preset Mutator Free
Create Vital, Serum 2, or Arturia Pigments preset starts from scratch, from one preset, or from one short audio source.
Preset Mutator Free is a local-first browser tool for quick synth sketches: playable starts you can finish inside Vital, Serum 2, or Pigments.
Runs locally in your browser. No AI preset generation. No uploads or stored presets/audio.
Free creates 3 individual presets. Pro creates 32-variant ZIP packs for Vital, Serum 2 beta, and Pigments beta.
Processing happens in the browser, so source material does not need to be uploaded.
No AI generation: presets are built from local rules and curated seed data.
The free tool exports three individual presets per run; Pro expands the workflow into a 32-variant ZIP pack.
Default
From Scratch
Choose intent, mood, register, and shape controls to generate a quick playable idea without a source file.
Preset source
Mutate Preset
Load one `.vital`, `.SerumPreset`, or Pigments `.pgtx` file and create related variations while keeping the original identity close enough to refine.
Audio source
Audio to Preset
Analyze one short sound locally and turn it into Vital, Serum 2, or Pigments preset directions. Best for simple tones, textures, drones, and focused one-shots.
Formats
Vital stable, two formats in beta
Vital export is stable. Serum 2 and Arturia Pigments generation are available as beta targets.

Gumroad license-key verification needs an internet connection. Your key is saved in this browser; earlier signed Pro tokens still work.
Preset generation stays local. Activation sends your license key to Gumroad for verification, not your source presets or audio.
