Audiobus 3 • Hosting AUv3 Audio Unit Extensions • Switchable FX Trails • And many improvements and bug-fixes


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 autorecord or a countin 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.


Create up to 4 tracks with endless layers of overdubs to build your performance. Create a 1 bar percussive loop on track one, a 4 bar chord progression on track two and layer a bass line on top, all in perfect synchronisation.
Record a Chorus, Verse and Bridge  in each track and switch between them seamlessly, or use the new serial-master mode to create a percussive master track that play’s in sync with your chorus, verse and bridge.


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.

Ableton Link you lets you even play in time 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.


“Totally sick, pro looper and just overall solid product”

“The best iOS looper !”

“Forget ***** and all the others, this is the one !”

“This is like a RC-500 on steroids.”



MIDI clock master lets Quantiloop control your favourite app or hardware device. MIDI slave lets Quantiloop follow the pace of your drum machine. Inter-App Host sync follows the tempo of your DAW. Quantiloop will start and stop together with the host/master. And Ableton link lets you sync wirelessly to other apps. Absolutely no excuse to be out of sync.


Input FX lets you assign up to 3 simultaneous effects to the input. The processed audio will be recorded into your track(s). Use the transpose effect to convert your guitar into a bass or add some compressor to your voice. You can even host your favourite Amp Sim or any other Inter-App audio or AUv3 effect.
Output FX lets you assign up to 3 simultaneous effects to the output. FX can be applied to a single track, all tracks or the combined output. FX included are tape-stop, fade, reverse, transpose and more. Use the tape-stop to add some drama or introduce a key-change with output transpose. And of course you can host your favourite Inter-App audio effect or AUv3 as a track effect as well.
Each effect can be triggered by MIDI so your hands are left free.


Humbly inspired by Ed Sheeran‘s custom Chewie Monsta loop pedal, Arm Mode reduces the need for tap dancing and accidental overdubs.

When Enabled the Arm Mode disables overdubbing, allowing you to easily start and stop individual tracks without the need for double taps or dedicated stop buttons for each track. As it disables overdubbing it also avoids accidental overdubs, and lets you choose between overdub after record or play after record. Just press the track button to overdub, or the arm mode button to start playing.

When no audio is playing Arm Mode lets you choose which tracks you want to start when pressing the start button. 


Lay down a percussive loop or use the rhythm guide to practice your timing. Record a 12 bar blues progression and practice your soloing skills, or import your favorite backing track from the music library, the cloud or any other app and jam along. You can store your phrases in an empty preset slot so you can pick up where you left off the next day. Quantiloop will be your favorite session partner that never lets you down.


Technologies like Audiobus (2 and 3)Inter-App-Audio, AUv3 Audio Unit Extensions and Ableton Link enable you to connect to virtually any app or device. Host Quantiloop in the effects chain of your Amp Sim, connect different fx processing apps to each of the individual Audiobus ports, or route them to your multi track recorder. The possibilities are only limited by your imagination.

MIDI controller assignments let you assign taphold and double tap actions to each controller, so you can control the looper the way you want. Assign all actions for a track to one controller or if you prefer a separate controller for stop, undo/redo or clear, split them between multiple controllers. It is all up to you.

Manage your set lists in banks. Create a bank for each setlist. Assign a midi controller to move between presets within a bank (or setlist if you prefer). MIDI Program Changes are supported as well. No hands required when your on stage.
