About

Midiflow

This app enables seamless MIDI data transfer between different applications on your device. It allows for app synchronization, routing MIDI from sequencers to synths, and assigning keyboard zones. Users can save and recall configurations, and monitor MIDI activity.

Highlights
  • App-to-app MIDI routing
  • MIDI clock synchronization
  • Channel filtering and remapping
  • Note and velocity manipulation
  • Custom virtual MIDI ports
  • Preset saving and recall
  • Controller filtering and remapping (in-app purchase)

Midiflow allows you to send MIDI from app to app in a similar way to what you already do with audio. That way, you can sync apps with each other or send MIDI parts from a sequencer app to different synth apps. You can also route the MIDI from your keyboard to apps and assign different key zones to them. Different settings can be stored as a preset, recalled later and inserted into another preset. Furthermore, all MIDI transfer can be monitored in order to find problems or just to learn what MIDI is doing (normally) behind the scenes. Important news: There is a full documentation on the Midiflow website now! HOW DOES IT WORK? Midiflow allows you to create multiple routings. Each routing receives MIDI data on its source and sends it to its destination. The selectable sources and destinations include your CoreMIDI compatible MIDI interface and other apps if they provide a virtual MIDI port. You can also create custom ports that can be used by other apps to receive data from Midiflow or send data to it. A routing also has a modifier which allows you to filter data or modify it. That way, you can transpose notes, limit them to a key range, change the MIDI channel of the incoming data, etc. (see the feature list below). LIST OF FEATURES + MIDI clock – specify tempo and your apps will be in sync + Channel filtering and remapping + Velocity filtering – a routing is only active for notes in a given velocity range + Note shift – shift all notes by a given number of half-tone steps + Note remapping – shift each note individually + Velocity remapping – apply a velocity curve, transform to fixed velocity, or specify the map value by value. In the latter case, you can also export the mapping to the clipboard, edit it in another app like Apple Numbers, and paste it back in Midiflow + Filtering out Clock or dividing the tempo into subdivisions + Filtering out SysEx + Connect to other iPads/iPhones via Bluetooth MIDI (iOS8 or higher) + Save a configuration as a preset, which can be recalled later or inserted into another preset + Custom virtual MIDI ports, which can be selected in other apps as a source or destination + Control aspects of Midiflow via MIDI. For example, select presets or control the clock with any MIDI command + Launch your synth apps from Midiflow (works with an increasing number of apps) + Sharing your configurations ADDITIONAL FEATURES (available as an In-app purchase) + Filtering and remapping of controllers – transform (a) the controller type, e.g. from CC1 to pitch-bend or note value to CC1, and (b) transform the value in several ways: as a linear remapping from an input range to an output range, as a curve, or as a value by value list. In the latter case, you can also export the mapping to the clipboard, edit it in another app like Apple Numbers, and paste it back in Midiflow. This allows you to create very sophisticated remappings. + Controller conditions – adjust your routings depending on other MIDI messages. This allows you to create sophisticated behavior within your setup by switching routings on and off. DOES MIDIFLOW WORK WITH MY SYNTH APPS? Midiflow works with every app that has a correct MIDI implementation. In the best case, it has an own virtual MIDI port and can be configured so that it receives MIDI only on that port. Unfortunately, some apps don't have that, but can at least be restricted to one MIDI channel. In that case, you can send to that channel on the global MIDI port "Network Session 1". If you can't select a channel either, then the app won't work with Midiflow. There is a tutorial video on www.midiflow.com that explains this in more detail.

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.

Verdict

The call

The clearest difference is rating: Quantiloop Pro at 4.9 against Midiflow's 4.0. Quantiloop Pro also leads on review sentiment (94% vs 59%) and in-app purchases (none vs 3). Midiflow's advantage is price ($7.99 vs $14.99) and update cadence (every 5 weeks vs every 3 months). On ads and device support there is nothing between them.
