About

LoopGround

Features
Read full description

LoopGround is a four-track tape looper for building slow, evolving music. Record or bring in sound, then let each loop run at its own length, speed and direction while wow, flutter, saturation and tape age turn it into something alive. • Four independent tape loops, each with its own length, speed and direction • A step sequencer with chords, chance, ratchets, a key and scale, and an arpeggiator • Three LFOs and a filter on every track to keep everything moving • A mixer with EQ, aux sends and returns, and insert slots for your own AUv3 effects and instruments • Afterlight — a lush reverb with shimmer, freeze and burst • Run Away Delay — a pattern-driven delay that repeats, reverses, pitches and scatters • Use it as a standalone app, or as an AUv3 plugin inside your favourite host • Designed for iPhone and iPad, in portrait and landscape Try everything free for 7 days. Then choose LoopGround Full, or LoopGround Lite — the tape looper and sequencer without Full's extras (loops up to a minute, no per-track step lengths or divisions, no instruments or MIDI out, and no Afterlight or Run Away Delay). Lite owners can upgrade to Full at any time. Already own LoopGround Full for Mac or Windows? Sign in with the email you bought it with and it unlocks on your iPhone and iPad at no extra cost.

Make a fist to stop. A SOUND FOR EVERY MOOD • Theremin: the classic eerie wail • Dusk: a dark, slow, melancholic synth • Aura: an airy, voice-like pad • Glass: a soft, bell-like shimmer • 8-Bit: a video-game square wave ALWAYS IN TUNE Auto-Tune snaps you to a scale (major, minor, pentatonic or every note) in any key. Hard for the robot effect, Smooth for a gentle glide. PLAY A DUET Turn on Duet Mode and each hand becomes its own instrument, with its own sound and settings. MORE TO PLAY WITH • Reverb and Pulse effects • Volume and octave for each hand • Make a fist to mute without hiding your hand • Portrait or landscape, iPhone and iPad PRIVATE BY DESIGN Hand tracking happens entirely on your device. Nothing is recorded, uploaded or collected.
