Loopr is a low latency loop recorder and player. Compose, practice, jam along, or sample audio soudscapes easily. Created by long-time expert loopers, it is focused on ergonomy and simplicity via one-finger controls but also hands-free MIDI pedalboard compatibility.

Synchronizing drum machines and sequencers is easy via its precise MIDI out sync. Enhance your live performance using automatic multi-layer 'fast' or 'one-shot' recording modes.

Loops can be exported as independent files (including tempo and time signature information), for you to share the groove or use with most desktop audio production apps (e.g. Logic Studio, Garage Band, ...).

Loopr is CoreMIDI and CoreAudio compatible and enables you to use most popular iOS compatible interfaces.
