- Play In Key
- Every note and chord stays in your chosen scale. Explore freely without getting lost.
- Layer Loops
- Eight tracks for synths, samples, and multiple drum kits at once. Record and overdub while the loop keeps moving.
- Synth Sound Design
- Shape each synth with dual oscillators, envelope, filter, motion, and a full effects rack. Browse built-in Recipes or save your own.
- Sampler
- A 4×4 pad grid of your own audio on any track. Import or record from the mic, play one-shots or pitched Keys, chop loops into new pads, and overdub into the loop like Notes.
- Drums
- Load a kit on any track and layer as many drum machines as you need. Full EQ and FX on every drum track, just like synths and samples.
- Song Mode
- Build multiple loops and arrange them into a full song. Jump between loop scenes live while you perform.
- Pulse & Arpeggiator
- Repeat notes and hits with Pulse, or latch curated ARP patterns on synth tracks. Keep phrases locked to the tempo when the transport is running.
- Edit & Tighten
- Quantize and humanize per track, then open the grid editor to move, resize, and delete recorded notes, chords, drums, and samples.
- Save & Sync
- Save as many songs as you like. Everything syncs through iCloud between iPhone and iPad. Export as WAV or AAC when a moment is worth keeping.
- Built For Performance
- Notes, Chords, Drums, and Sampler up front, with mixer, FX, and sound design always a tap away. Optional MIDI input for external controllers.
A Look Inside
Built By One Person.
ARC-24 isn't backed by a large company.
