Capture the idea. Shape the notes. Make the track.

COMPA is a sampling and music-production studio for iPhone and iPad. Work with its included instruments, your AUv3 collection, or your grooveboxes. Hardware is optional.

FROM A PERFORMANCE TO A SONG Capture recent MIDI or save recent audio with Audio Recall, even when the idea arrives before Record. Move patterns and CHOMP sequences into Launch or Arrange, edit the copy and build the song. Draw notes in an expanded piano roll, use named drum rows and per-part chromatic views, shape velocity and expression, and drag playback-loop start/end handles. Record fixed-length MIDI with Overdub or Replace. Export MIDI to another sequencer, or print the performance as audio.

RHYTHM DOG 808 + RAW DOG 303 RD808 is COMPA's included drum synth and AUv3: seventeen parts, kit and chromatic playing, drum-grid and piano-roll editing, repeat brushes, motion recording and a factory rhythm collection spanning 63 genres. Generate a groove, refine it and send it straight to Launch or Arrange. On a wide window, keep the sequencer and mixer side by side.

Raw Dog 303 brings acid basslines, slides, accents, modulation, stereo effects, pattern generation and note/knob recording. Its updated piano-roll and library workflow fits into the same song-building process. Both instruments are included, with AUv3s for compatible hosts.

CHOMP: MAKE THE SAMPLE YOUR INSTRUMENT Record, import, trim, tune, reverse, loop, layer and resample. Play on screen or from a controller, then refine a recorded sequence in the expanded editor. Start a new Session with empty pads or a default kit you choose. Quota Kits inside CHOMP builds, imports, converts and exports sampler kits. Quota Stems separates drums, bass, other and vocals on device. Quota DS turns selected speech into playable phrases. CHOMP AUv3 is included.

A CONNECTED STUDIO Host compatible AUv3 instruments and effects. Use channel inserts and sends, movable editor windows, Narrow/Wide mixer strips and held-peak metering. Route MIDI between supported hardware and apps, set Notes, Clock and Start/Stop separately, map controllers and save Sessions/templates. Connect compatible USB MIDI gear and audio interfaces, with Ableton Link options for your setup.

PERFORM IT YOUR WAY Scratch and blend with COMPA DJ, isolate a part with Stem Decks, or reshape a sample with Pad Scratch. The included DJFX Looper COMPA edition is also available as an AUv3 effect. Visual Pads add video trimming, color/effect controls, automation, crossfades, recording/replay and MP4 output, with separate picture-only external display output.

YOUR WORKSPACE, WITH HELP CLOSE BY Choose coats inspired by Hunny, Boogie, Bella and ChaCha, plus brindle, wood and worn-metal surfaces. Customize card colors, fonts and icons. Refined phone/iPad layouts and text-size options make better use of the screen. Explain Controls gives specific help and opens the relevant highlighted passage in the complete offline manual. Key and tempo suggestions remain adjustable.

ON YOUR WRIST The Apple Watch companion brings MIDI/audio Capture, transport, Crown and tap tempo, Arrange arm, bar/beat, complications and haptic confirmation. Haptic Beat works while the Watch app is active, with its paired iPhone.

One upfront COMPA purchase. No COMPA subscription, account or in-app purchases. Third-party apps and hardware are separate. Other-app audio capture requires iOS/iPadOS 27, supported source playback and system permission. Optional models and imported media use device storage.
