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.


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.

New favorite looper


I stumbled on this app about two weeks ago and I’ve been down a rabbit hole ever since! I paired it with a Focusrite interface with 10 outputs and have discrete outs for all four tracks in stereo plus whatever I’m feeding into the input.
This is HUGE! I have been thinking about a looper with discrete outputs for many years. I run it in sync with my DAW and ended up with a session that is very editable and way more useful in composition than loops that are stuck together in one pair of outputs.
The time stretching sounds really good also. Combine these features with the slew of triggering and sync and IO options and you end up with the most complete looping solution I have ever come across. I have them all from the Echoplex Digital Pro through the crazy EHX offerings. They can’t hold a candle to this app.

Quantiloop Customer service


Hi to all :),
This is my first ever App Store review.
The Quantiloop app in itself is Nothing short of amazing. When I first open the app I had a rough start getting operations to go (most issues were because of the operator of the app ) and had to call tech-support. The reply from tech-support was extremely fast and very thorough and attentive to the issue that I was having and was cleared up immediately. I’ve asked questions about certain operations that I wanted for myself with the app and All replies were timely and extremely helpful I give this app a five star rating and highly recommend it to any individual.

Better than hardware loopers so far


After giving up on hardware loopers, I gave this software a try. It has features that you only wish hardware loopers to have and if one day they do, you have to pay a lot. Don’t believe me, download it and try the demo version. I test it with JamUp Pro, iRig HD 2 and these drum software: Drum Beats+, Rock DM and DM. I created a track for drum, another for guitar rhythm and a third track for lead guitar. I was able to use different length for each track. Drum sync worked well and quantization behaved correct. Learning curve is not steep.
