Compa: Groovebox Companion

COMPA is a sampling and performance studio for iPhone and iPad.

Record new sounds, turn dialogue into playable phrases, scratch your tracks and build a song. Use COMPA's instruments, including Raw Dog 303 (RD303), or connect compatible AUv3 apps, MIDI gear and audio interfaces. Hardware is optional.

SAMPLE APPS, THE WEB AND YOUR GEAR
Capture supported other-app audio on iOS/iPadOS 27, open a web player inside COMPA, or record hardware and hosted instruments. Send audio straight to CHOMP pads, Clips, Arrange, Takes or Quota DS. Hold for a quick sample or tap to record while you switch apps. Audition, keep sampling, and share web links into COMPA without copying and pasting addresses. Audio Recall saves recent audio when inspiration arrives before Record.

QUOTA DS: TURN WORDS INTO SAMPLES
Transcribe audio, search the transcript and highlight the words or phrases you want to play. Audition the selection, refine its timing and fades, then send it to CHOMP. Q-Chop helps make sentence and segment cuts. Saved transcripts, flexible reading layouts and a resizable workspace keep longer recordings manageable. Choose Apple speech recognition or an optional downloadable Whisper model that runs locally.

CHOMP: PLAY WHAT YOU FIND
Record, import, trim, tune, reverse, layer, sequence and resample. Play samples chromatically in Mono or Poly. Perform Live FX, map controls to MIDI and route the standalone FX bank to CHOMP's master or a bus. Quota Stems separates drums, bass, other and vocals on device. Quota Kits imports and exports sampler kits. CHOMP AUv3 is included for compatible hosts.

DJ DECKS AND PAD SCRATCH
Load Files, song clips or CHOMP samples onto Deck A and Deck B. Scratch, set hot cues, loop, adjust pitch and levels, and mix with EQ, filters and crossfader curves. Analyze tempo and cue suggestions, map performance controls to MIDI, and record your performance. Open Pad Scratch for a single sample, add Cut, Brake or Echo Out, and send the recording to a new pad.

RAW DOG 303: INCLUDED BASSLINE SYNTH + AUv3
Meet Raw Dog 303! Create basslines with RD303's 128-step sequencer, pattern library and generator, modulation, stereo effects and note/knob automation recording. It's built into COMPA and included as an AUv3 instrument for other compatible music apps. No extra purchase or unlock.

FROM IDEAS TO SONGS
Launch Clips and scenes, arrange audio and MIDI, draw automation and mix with AUv3 inserts and sends. Import files where you're working, move and copy clips, normalize audio and export mixes or stems. FETCH develops chords, bass, melody and drums; Guided FETCH works through parts one at a time. Capture linked video, perform it from pads and export MP4 with your audio.

A COMPANION FOR YOUR SETUP
Tailored workspaces give supported grooveboxes and synths direct controls. Compatible MIDI ports also work without a device profile. Set note channels, Clock and Start/Stop independently, map controllers, assign analog returns through an audio interface, and save your rig with the Session. Sync through Ableton Link, with optional transport and compatible Link Audio connections.

One upfront COMPA purchase. No COMPA subscription, account or in-app purchases. RD303 and its AUv3, CHOMP, Quota DS, Quota Stems and Quota Kits are included. Third-party apps and hardware are separate.

Other-app capture requires iOS/iPadOS 27 and depends on source playback and system permissions. Optional models and imported media use device storage; selected cloud files download for playback/editing. USB MIDI and USB audio are separate device capabilities.
