I built a free desktop editor + preset backup tool for Valeton GP-series pedals (GP-5 tested)
Hey all — I own a Valeton GP-5 and the one thing that always bugged me is that there's no way to back up your presets. One factory reset and everything's gone, and there's no official desktop app to organize your tones.
So I built one: GP Multi Editor. It connects over USB and lets you:
- Edit everything live (amp, cab, drive, delay, reverb — models, knobs, on/off, chain order), and it follows the pedal's footswitch back
- Back up all 100 presets to a single file
- Import/restore any patch in one click, 100% faithful (every parameter, bypass state, effect order)
- Share tones with other players as files
The editor is free. The full preset librarian (backup/organize/import) is a one-time unlock — no subscription. Works offline after a one-time activation. Windows only for now.
It's fully tested on the GP-5. The rest of the GP line (50/100/200) shares the same system but is experimental — the free version lets you check if it connects to your unit first.
Fully independent project, not affiliated with or endorsed by the manufacturer. I made it because I wanted it.
Would love feedback from anyone with a GP pedal: gpmultieditor.tonscott.com.br
(Happy to answer questions and take feature requests.)
