Help

Getting Started

• Load a .prst file by dragging it into the editor or clicking "Load preset from disk".
• Click on an effect slot to adjust parameters. Toggle effects on or off with the LED button. Switch between pedal view and list view.
• Click "Save preset as file" to download your edited preset as a .prst file.
• Drag and drop effect slots to reorder the signal chain.
• Each .prst file contains an author name (max 16 characters). You can view and edit it in the editor.

HX Stomp Import (Experimental)

• Load a .hlx file from a Line6 HX Stomp. The app automatically converts it to GP-200 format.
• This feature is experimental. Not all HX Stomp effects have a GP-200 equivalent — unmapped effects are skipped or approximated.
• Converted presets include effect types, parameters, and signal chain order. Review the result in the editor before saving.

USB MIDI Connection

• Web MIDI is only supported in Chrome and Edge. Firefox and Safari are not compatible. Chrome also runs on Linux (e.g. Linux Mint) — Preset Forge is the only GP-200 editor with Linux support.
• Connect your GP-200 via USB and click "Connect GP-200". The browser will ask for permission to access the MIDI device. Progress is shown live (Identity, Firmware Check, Slot Names).
• Changes in the editor are sent to the device instantly: toggling effects, changing parameters, and reordering the signal chain. The device bar at the top shows the current slot and stays visible while scrolling.
• Use "Load" to pull a preset from the device. Click "Save to [Slot]" to save your changes directly to the device.
• Double-click the preset name in the device bar to rename it directly (max 16 characters).

Gallery

• Sign in and upload presets to your profile. Publish them to the gallery so others can discover them.
• Each preset gets a unique share link. You can reset the link at any time to revoke access.
• Browse the gallery for presets from other users and download them directly. Filter by style or module type.

Bank Navigation

• When you load a preset via USB, the entire bank (A/B/C/D) is loaded. Switch between the four slots using the tabs.
• Use the arrow buttons on the left and right of the tabs to navigate to the previous or next bank.

Playlists & Cue Points

• Create playlists with songs for your practice sessions or live performances. Each song can have multiple presets assigned.
• Select device slots from your GP-200 to associate with each preset in a song. Presets are pushed to the device when activated.
• Add timed cue points to songs: at a specific timestamp, the app can automatically switch presets or toggle effects on the device.
• A 3-2-1 count-in is shown before each cue point triggers, so you can prepare for the preset change.
• If the USB connection drops during a performance, the app will attempt to auto-reconnect without losing your playlist position.

Keyboard Shortcuts

• Arrow Up / Arrow Down — previous / next song in the playlist player.
• Arrow Left / Arrow Right — previous / next preset within the current song.
