Built for Live performance and hands free use, Quantiloop recreates the simplicity of a hardware loop pedal in an iOS app. Attach a MIDI foot controller and control it the way you want. No MIDI controller at hand; just preset your loop length, enable auto–record or a count–in and your loops will automatically close, no hands or feet required. Big onscreen controls allow for easy configuration and tactile control by vocalists or beat boxers. Focus on your performance instead of fiddling with dip switches or complex menu’s. Be Creative Create 4 tracks with endless layers of overdubs to build your performance. Record a Chorus, Verse and Bridge and switch between them seamlessly or create a 1 bar percussie loop on track one, a 4 bar chord progression on track two and layer a bass line on top, all in perfect synchronisation. Rhythm Guide The builtin rhythm guide provides a rhythmic backing. Use the internal metronome for practice, import drum loops from virtually anywhere or host and control your favourite rhythm apps to enhance your performance. MIDI master lets you control MIDI hardware, and MIDI slave lets Quantiloop follow it. Ableton Link lets you even play in time over WiFi with external apps and devices. Quantisation aligns your actions to the nearest measure or beat so you stay in time, and real-time tempo control sets the pace. Prefer setting your own pace, disable quantisation and Quantiloop will react to your actions with minimum latency to create tight synchronised recordings. FX Assign up to 3 simultaneous effects to the input. Use the built-in transpose to covert your guitar into a bass, or host your guitar amp sim directly in Quantiloop. The results will be recorded into your loops. Or assign up to 3 simultaneous track effects to the output. Use the tape stop to add drama, introduce a key change to build up your performance, or host an Inter-App audio/AU reverb processor. Track FX may be assigned to a single track, all tracks or the combined output.
