Choppa
More instrument than sampler.
Record or import anything, it splits into pads, and you play the remix. Standalone, or inside any Audio Unit host.
Why Choppa Exists
Finished audio in, instrument out. A vocal, a guitar loop, a whole beat — sliced across your keyboard. It came from wanting to remix my own loops by playing them, not dragging them around.
How Choppa Is Different
Koala, Reslice, Samplist, Segments — deep samplers. Choppa isn't competing on features; it's competing on speed. Load. Slice. Play. Want a full sampler? Use one. Want to play right now? This.
How It Works
Load & Slice
Drop audio in, or bounce from x1/x4. Auto-divided — turn the count up for hits, down for phrases.
Play & Perform
A 4×4 grid on your keys. One-shot, loop, reverse, choke. Play the loop — don't stare at it.
Shape & Export
Per-slice regions, forward/reverse/pingpong, a moving window. Export what you love back into x1 or x4.
Find your way in
Guided training
Follow the highlighted controls to record, chop and play. Pause anytime. Open TRAINING in the title menu to resume, replay or reset your progress.
Room to play
Turn sideways and the library and inputs dock beside the instrument. Sequencer slides follow your movement, pauses and release timing.
Library updates
In TestFlight and Mac Preview, cloud files show loading progress with cancel and retry. The WAVELOOP pool shows shared recordings with names and waveforms, and imports working copies through the trim window.
Does Unload delete my recording?
In TestFlight and Mac Preview, Unload frees a downloaded iCloud file’s local space and Choppa’s temporary preview copy. The cloud original stays intact; LOAD brings it back. Long-press in FOLDERS on iPhone or iPad, or right-click on Mac.
Does resetting training erase my samples?
No. RESET ALL TRAINING restarts the guides and discoveries while keeping your audio and settings.
