Load your sounds. Shape them. Press play and let them evolve. Layers is a 10-track ambient looper built for sonic exploration on a whim — in the studio, on stage, or out in the field. Import samples from your library, Files, export to Layers via Voice Memos, or record the world around you. Trim with a waveform display, loop seamlessly with crossfade blending, and shape each track with reverb, delay, and filters. Control speed and pitch independently. Shake to randomize everything. When you're done, export a high-quality master or individual stems for your DAW. Layers is also built for live performance — alter settings in real time while audio loops infinitely in the background. Fifteen themes. A demo project to start immediately. An interface designed to disappear between you and your sound. No subscriptions. No ads. No in-app purchases. Just the instrument.
