Download Synth2Software
Free forever, and it is the full application and the full plug-in — desktop and in your DAW. 20 randomizations, 3 conversions and 3 auto-sampler runs a day, every synth, every patch editor. When it starts earning its keep, pick an edition.
A free account is required — Synth2Software needs a license
key to start, and your key is issued with the account. It takes a moment,
no card, and the download carries on straight afterwards.

What you need
Windows 10 or 11, or macOS 12 and newer. A synth connected by USB or a MIDI interface. The VST3 plug-in installs alongside the app and runs in any DAW that hosts VST3. The randomizer writes to the temporary patch area, so nothing in your synth's memory is touched unless you press Save on the unit yourself.
Prefer not to install anything?
The browser randomizer runs the same engine in Chrome, Edge, Brave or Opera with no download at all. It needs Web MIDI, which Safari does not have.
