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.

MeloVox is an AUv3 vocal harmoniser designed to allow up to 5 simultaneous harmonies. You can either choose to have MeloVox automatically generate harmonies by listening to live input and creating harmonies based on the pitch of the incoming vocal, or you can use MIDI input to choose how to pitch the harmonies. You can choose from one of two algorithms, one more suitable to vocals which includes formant preservation, and another more traditional option for instruments. Unlike many pitch shifters, MeloVox is build on a phase vocoder capable of formant preservation, meaning much more natural sounding vocal harmonies. This is especially noticeable when pitching a vocal up an octave, which results in what is often called the Mickey Mouse effect. This is due to the fact that all frequencies are transposed up, along with the respective peaks in harmonics. This results in a sound which the vocal tract is incapable of producing, so it no longer sounds like a natural voice. MeloVox fixes this issue by preserving the formants. MeloVox is capable of producing up to 5 additional harmonies on top of the original vocal, and how it does that is down to the control mode setting. There are 5 different modes to choose from including Auto Sense, Fixed Pitch and three MIDI controllable modes called Chords, Melody and Vocoder. Auto Sense mode detects the frequency of the incoming vocal, and automatically harmonises using the specified key and scale. Fixed Pitch allows you to specify fixed offsets in a scale without the need to detect pitch. Chord and Melody modes use incoming MIDI data to precisely control the harmonies using MIDI notes from your master keyboard or DAW. And to top if off we have a traditional 12 band Vocoder which is incredibly easy to setup and use due to its internal carrier source. MeloVox includes a build in noise gate to remove unwanted background noise that helps with pitch tracking, and a vocal doubler which adds a spacious stereo effect to any monophonic vocal. MeloVox also features a 10 Band EQ add a reverb. All effects can be applied to either the original vocal or just the harmonies. A built in preset manager helps organize presets into categories using drag and drop, and the Set List can be created to provide quick real-time switching between presets and snapshots during a live session. You can even add your own acappella vocals to test out your presets as you create them.
