Performance Editor Mastermind preset workspace on Mac

Program the show, not the pedal.

Open an existing .rjs file offline or connect a Mastermind GT over USB-MIDI. Edit on the bigger screen, then write the finished setup back to the hardware.

01 / SEE IT

The real pedal surface

Your labels, LED colors, pages, and switches are drawn together instead of remembered one menu at a time.

02 / ORGANIZE IT

Music-first structure

Move between presets, songs, and setlists without losing the relationship between them.

03 / PROTECT IT

Offline files, live sync

Edit and back up .rjs files without the pedal, then pull from or write to real hardware when connected.

Your settings stay with your rig.

OfflineOpening and editing an .rjs file requires no pedal and no network connection.
Live hardwareConnect over USB-MIDI to pull settings from the pedal and write changes back.
PrivateNo account and no network requests. Your files and settings stay local.
