Unofficial web editor for the Valeton GP-5 and GP-50. The connected model is detected automatically.
It needs a browser with Web Bluetooth
(Chrome or Edge on desktop / Android, Bluefy on iPhone / iPad) and a device with Bluetooth.
This is the USB version: it needs a browser with Web MIDI
(Chrome or Edge on desktop / Android) and a USB data cable.
Over USB the pedal does not report some changes made on the pedal itself (global settings, footswitch mode and CTL presses); reconnect to refresh them.
Editing
- Click a block in the signal chain to edit it; double-click to switch it on or off.
- Drag NR, PRE, MOD, DLY and RVB to change their position in the chain.
- When N>S (NAM / Snaptone) is on, AMP and CAB are bypassed (shown in red).
- Save writes your changes (and an optional new name) to the current patch.
- GP-5: tap tempo sets the delay time (quarter, 8th or dotted 8th). Global BPM keeps it when you change patches.
- GP-50: tap tempo sets the patch BPM. Turn on Sync in MOD, DLY or Crier to set the rate / time as a note value (1/4, 1/8d…).
Live mode
- Four footswitches (A–D) work like a MIDI pedalboard: each one loads the patch assigned to it, and its LED lights up while that patch is active.
- Press Assign (or an empty footswitch) to choose its patch. Assignments are saved in this browser, separately for the GP-5 and the GP-50.
- Every patch has its own eight scenes (1–8), like the scenes / snapshots of bigger multi-effects; they are shown in both normal and live mode: outside live mode, press an empty scene, give it a name (up to 10 characters) and the pedal is read to store which blocks are on and the parameters of the active ones; press a stored scene to send it back to the pedal. When you change patch, its own scenes appear. × empties a scene (only outside live mode, so it can't be pressed by mistake on stage). Scenes are saved in this browser, separately for the GP-5 and the GP-50.
- Scenes do not change the effect models (the pedal would reset their parameters to the defaults). If the current patch uses another model in a block, that block is only switched on or off and the status bar warns about it. Gap sets the time between messages.
Keyboard
| 1…0 or Q…P | Switch blocks on/off (NR, PRE, DST, N>S, AMP, CAB, EQ, MOD, DLY, RVB). The letters work with the MVAVE Chocolate in custom keyboard mode. In live mode, 1…8 recall scenes 1–8 instead. |
| Space | Tap tempo |
| PgUp / PgDn | Previous / next patch |
| A…D | Footswitches A–D (live mode) |
