Is GP200 Studio free?

Yes. It is free and open source under the GPL-3.0 licence. There is no account, no install and no backend — the code is on GitHub.

Do I need a GP-200 plugged in to use it?

No. Without a device you can still build and edit patches and import or export .prst files. Live sync and saving to the unit need a connected GP-200.

What GP200 Studio does

GP200 Studio is a browser-based editor and loop station for the Valeton GP-200 multi-effects floor unit. Load, build, and edit presets entirely in your browser, then push changes live to a connected GP-200 over USB-MIDI. It's free and open source (GPL-3.0); the code lives on GitHub.

Note

Device features (live sync, patch management, saving to the unit) need a GP-200 connected over USB in Chrome or Edge. Web MIDI isn't available in Firefox or Safari. Offline, you can still edit patches and import/export files.
