ARC vs SUS4 Loop Builder

Eight tracks. Synths, samplers, drums. Play it like an instrument. ARC-24 is a groovebox for iPhone and iPad. Pads, loops, and a mixer in one place. Everything stays in key. Pick a key and a scale and the pads follow, so you can play fast without landing on a wrong note. Record a loop, keep overdubbing while it runs, and fix whatever you fumbled on the grid afterwards. Once you've got a few loops going, chain them into a song. Or leave the transport running and fire them off by hand from the mixer. • Eight tracks that sort themselves out. Synth, sampler, or drums, decided by what you play first. Overdub while the loop cycles. • Note and chord pads locked to your key and scale. Hold latches notes so they sustain. Pulse retriggers them on the beat. • A sixteen pad sampler. Import WAV, AIFF, MP3, M4A, AAC, or FLAC, pull audio from a video, or record through the mic. Chop it into slices across the grid, or map one sample over every pad and play it pitched, in scale or chromatic, at the original length or at tape speed. • Ten drum kits, from 909 and trap to lo-fi, boom bap, and hand percussion. Tune, pan, and level every pad. • Synth editing that goes deep enough to matter. 21 presets to start from, two oscillators, filter, envelope, and LFO when you want to build your own. Save the keepers. • 25 arpeggiator patterns, all of them in your key, from slow drifting phrases to sixteenth note runs. • A piano roll editor. Move, stretch, and delete notes while the loop keeps playing. • A real mixer. Faders, pan, mute, solo, and three band EQ on every channel. • Every track gets its own effects rack, not a shared send. Resonant low and high pass with cutoff and resonance. Compressor and gate. Distortion, bit crusher, ring mod, flanger. Tempo synced delay in digital, analog, or tape. Reverb with chorus and tape wow. Character for texture, air, width, and warmth. • Motion, so synth parts never sit still. Slow LFOs drift the filter as the loop runs, and Bloom opens the cutoff every time you play a note. • Song mode. Arrange loops into sections, or switch between them live from the mixer without ever stopping. • MIDI in from a USB or Bluetooth controller. • Export to WAV or AAC. • iCloud. Start something on the iPad, pick it up on the phone. Seven days free, the whole app. After that one purchase unlocks it for good. No subscription, no renewal, nothing to cancel.

Record a part, loop it, and stack the next one on top. Up to eight tracks, each with a level control, so the idea sounds like a song before you leave the room. Fully on-device: no cloud, no account. Start with a chord loop, add a bass line, then a melody. Undo the last layer if it was wrong. When it works, export the mixdown as an audio file. • Up to 8 loop tracks, with level and mute per track • Undo the last layer • Export the mixdown as an audio file • A library of saved loop sessions For guitarists and singers building song ideas, beatboxers, and anyone who uses a loop pedal on stage and wants one in their pocket. Pro, or SUS4 All-Access across the whole range, adds reverb, delay and 3-band EQ on each layer, stem export (every track as a separate file) and unlimited saved loops.
