Deconpose: Practice Any Song

Split any song into stems and practice your instrument with the real band. 100% offline, powered by on-device AI. No subscription required.

Deconpose splits any song into its individual instruments — vocals, drums, bass, guitar, piano, and more — right on your iPhone or iPad. Mute the part you play and jam with the real band, or solo a single instrument to hear exactly what it plays. No uploads, no account, no subscription.

PRACTICE WITH REAL RECORDINGS

• Mute your instrument and play along with the original recording
• Solo any stem to learn a part note by note
• Set each stem's volume with its own channel fader
• One-tap presets: Guitar Practice, Bass Practice, Drumless, Karaoke, Vocals Only, Full Mix

INSTANT KARAOKE & BACKING TRACKS

• Mute the vocals in any song and sing with the original band
• Deconpose plays the music — it doesn't display song lyrics
• Or solo the vocals to study a melody or practice your singing

LEARN AT YOUR OWN PACE

• Slow playback down to 0.25x or speed it up to 2x — without changing the pitch
• Transpose up or down 12 semitones to match your tuning or vocal range
• Loop difficult sections with draggable A-B markers
• Drop bookmarks for intro, verse, chorus, solo, and outro
