MatchPatch
Watch the demo video · Read the documentation · Download MatchPatch
No more unexpected volume jumps when switching sounds.
MatchPatch automatically equalizes the loudness of presets and snapshots in guitar processors such as the Line 6 Helix.
Why MatchPatch?
You create a great clean sound. You create a great lead sound. Then you switch between them and one is much louder than the other.
MatchPatch measures your presets and calculates the gain adjustments needed to make them consistent, so your setlist feels balanced before rehearsal or stage use.
Features
- Measure preset loudness automatically.
- Analyze snapshots.
- Calculate required gain corrections.
- Modify Helix setlists and presets.
- Test the workflow without hardware.
- Configure normal runs from the GUI.
- Use CLI and worker commands for advanced scripting.
- Open source.
Current Support
Current normal workflows support:
- Line 6 Helix
.hlsHelix setlists.hlxHelix presets- GUI-first workflows
Loopback and simulated modes are available for no-hardware tests. Hardware mode is for real Helix measurement.

Install And Launch
On Windows, download the latest installer from
GitHub Releases,
run MatchPatch-Setup-<version>.exe, then launch MatchPatch from the Start
Menu. The installed app bundles offline Help, available from the GUI.
For source checkouts, use the verified local setup commands below and see Developer Notes and developer commands for fuller setup details.
Install the optional GUI support and launch MatchPatch:
# Linux or WSL
scripts/sync-wsl.sh --extra gui
matchpatch-gui
# Windows PowerShell
cd C:\src\MatchPatch-windows
.\scripts\sync-windows.cmd --extra gui
.\.venv-windows\Scripts\matchpatch-gui.exe
Hardware measurement from WSL needs a synced native Windows runtime. See developer commands before using real Helix hardware from WSL.
