Demix: Deconstruct your songs.

Demix separates any song into its individual instruments, right on your iPhone or iPad.

Record or import a track and Demix splits it into up to six stems: drums, bass, vocals, guitar, piano, and other. Mute the vocals and sing it yourself, drop the guitar and play your part, or solo a single instrument to hear exactly what it plays. A per-stem mixer, finger scratching, and optional synth voices let you remix it however you like.

Demix also makes an automatic transcription of each part, shown as a piano-roll, guitar and bass tab, staff notation, a chord lead sheet, and karaoke-style lyrics. It is generated on-device and meant as a visual guide to follow along, not a note-perfect score.

Everything runs on your device. Nothing is uploaded, so your music stays private and works offline.
