Componere

Build songs from loops in minutes. Paint loops onto tracks, and Componere matches every loop to your song's tempo and key automatically.

Componere is a loop arranger for iPhone, iPad and Mac. Pick loops, paint them onto tracks, and hear a full song take shape.

MATCHES TEMPO AND KEY AUTOMATICALLY Every loop is time-stretched to your song's tempo and transposed to its key as you work. Componere reads ACID-tagged WAV files and Apple Loops, and falls back to tempo and key hints in the file name.

PAINT YOUR ARRANGEMENT • Draw loops onto tracks by the beat, bar or whole loop. • Drag a clip's edge to repeat it, or stretch it to fit. • Move clips along a track or between tracks. • Pinch to zoom, or fit the whole song and every track on screen.

HEAR LOOPS BEFORE YOU ADD THEM Browse your loop folders and audition any loop at your song's tempo and key with a single tap. On the Mac, loops play as you highlight them in the file panel.

MIX • Per-track volume, pan, pitch, mute and solo. • Loudness matching evens out loops from different libraries. • Export your song as a WAV mixdown.

YOUR SONG, ON EVERY DEVICE Turn on Sync Song Across Devices and the song you're working on is saved to your iCloud Drive as you go. Pick it up on your iPad, iPhone or Mac exactly where you left off.

PRIVATE BY DESIGN No accounts, no ads, no tracking. Componere works with your own loops and your own iCloud Drive.
