UndoLooperGO

Build verse and chorus live, with unlimited undo.

UndoLooper is a live-looping AUv3 plugin and Standalone app designed for pure flow. Build arrangements instantly, strip them back, and perform without jarring cuts or long-presses.

Most loopers are built for jamming — then you stop. UndoLooper is built for arranging. Use unlimited undo and redo as performance tools to structure songs on the fly. Strip a massive chorus down to just bass and drums in seconds. Bring it all back when the chorus comes around. Build proper song structure that reflects how songwriters actually think.


PERFORMANCE LOOPING

- Unlimited undo and redo, used as performance tools
- "Back 5" instantly drops five layers in one press
- "Bring It Back" recovers everything you've wiped — full sound returns instantly
- "Stop Echo" adds a curated, decaying tail when you stop playback. No more harsh, unmusical cuts.


TOTAL SESSION RECALL

- Save your audio AND your complete undo/redo history in a single .undoloop file
- Pick up tomorrow exactly where you left off
- Share .undoloop files with other musicians to collaborate or study how they build layers


NEAR-ZERO LATENCY, ZERO FRICTION

- Sub-1ms latency with iPad audio interfaces that support low buffer sizes
- Instant response on every press. No double-taps on midi pedals, instant response
- The only long-press is an intentional Hold-to-Clear. Deliberate and protects your work
- Standalone mode hooks directly into your audio interface for the lowest possible latency for Live-Looping


BUILT FOR THE STAGE

- MIDI learn maps to your foot controller via CC or Note messages — almost any generic or pro MIDI device can control UndoLooper
- Run multiple instances inside a single AUv3 host
- Map one looper's stop to another's play for seamless verse-to-chorus transitions
