The open source pedalboard you build yourself
OpenRig turns a Raspberry Pi 5, a USB audio interface and a touchscreen into a guitar multi-effects unit. Neural amp captures, impulse responses and LV2 effects, and rigs shared by the people who play them.
Recorded from OpenRig 0.10.1 at 1024×600. On TONE3000: Metal Zone MT-2 by @kosmicaudio, Peavey 5150 by @doubleyoud, Mesa 2x12 V30 IRs by @tonefactor, CE-2w by @matteocapuni.

Playing
Made to be played, not configured
The signal chain is the main screen. Blocks are drawn after the gear they model; tap one and its knobs appear under the rack. Nothing needs a computer once the card is written.
- Tap for the knobs, double tap for the editor, hold to bypass
- A/B, Mix and left/right splits, nested as deep as you need
- Neural amp captures and impulse responses next to any LV2 plugin
TONE3000, on the pedalboard
Browse your favourites and the trending tones right from a block; a capture loads in a couple of taps.
A Live page for your feet
Stomp, Scenes or Setlist mode, tap tempo, and footswitches on the GPIO or any MIDI controller.
Every core plays
A heavy rig is spread over all four cores of the Pi 5: more amps and splits at the same small buffer.
Built like an appliance
A read-only Buildroot image with a PREEMPT_RT kernel boots straight into the rack. Updates install next to the running system and roll back if they fail.
MIDI, Helix-style
Program changes for presets, CCs for scenes, looper, tuner and tap. Learn any knob to an expression pedal.
Real-time safe audio
New chains are built aside and crossfaded in. The audio callback never allocates or waits on a lock, and a crashing plugin never stops the sound.
