ARC-24: Multitrack Groovebox

ARC-24 is a multitrack groovebox for iPhone and iPad. Build loops and full songs across eight tracks — each one a synth, sampler, or drum part. Record notes, chords, drums, or samples and overdub while the loop plays. Lock everything to a key and scale, shape the timing, edit on a grid, then arrange your loops into a finished song. What's inside: • Eight tracks. Each track becomes synth, sample, or drums as you play — overdub while the loop runs. • Notes & Chords. Scale-locked pads, Hold for latched notes, and Pulse for rhythmic note or drum repeats. • Sampler with chop. Import or record audio, then slice it across the pads. • Drum machine. Swappable kits with per-pad tuning, pan, and volume. • Scale-locked performance. Set a key and scale so every pad stays in tune. • Quantize & grid editor. Tighten timing, then move, resize, and clean up hits on a piano-roll grid. • Arpeggiator. Multiple patterns that follow your key. • Mixer & FX. Volume, pan, mute, solo, EQ, plus a full per-track FX rack (reverb, delay, atmosphere, and more). • Song mode. Arrange loops into sections and full songs; switch loops live from the Mixer. • MIDI input. Play from a USB or Bluetooth controller. • Export. Bounce to WAV or AAC. • iCloud sync. Start a song on your iPad and keep working on your iPhone. Try it free for seven days. After that, unlock it once to keep it. No subscription and no recurring charge. Designed for iPhone and iPad.
