Midiflow update – MIDI utility app from Johannes Doerr gets further tweaks

Download from iTunes App Store midiflow logoI love my collection of iOS synths, guitar amp modellers and audio effects but, while ‘exciting’ might not be the word to describe them, I’m also glad I’ve got access to a number of very useful ‘music utility’ apps that I use on a regular basis. One of these Midiflow which I’ve reviewed previously here on the Music App Blog. Developer Jonannes Dorr first launched the app back in June 2014 but there had been a fairly regular stream of updates since then (suggesting a pretty active development process)…..  until February last year at least…..

Thankfully, a couple of further updates have appeared since the turn of the year and v. 2.2.12 arrived on the App Store over the week-end. This latest updates is a bug-fix one but preset sharing was added a couple of weeks ago and this provides a useful way to save/share configuration files.

The app is a universal one so will work on iPhone, iPod Touch and iPad (the screenshots shown here are from an iPad and, obviously, the layouts would be somewhat different on a smaller iPhone screen) and is currently priced at UK£5.99/US$5.99. This provides an impressive set of features for monitoring and adjusting your MIDI data flows but, if you want to go the whole nine yards, there are two or three additional IAPs that add further feature options. The app is a 14MB download and requires iOS8.0 or later.

Midiflow - like Audiobus - allows you to configure multiple signal chains for your various MIDI-based apps.

The essence of what Midiflow does is actually quite simple in that it allows you to route MIDI data from a source (app, external MIDI in, a MIDI keyboard/controller, a network MIDI connection) to a MIDI destination (an app such as a synth, drum machine or sequencer or, via a suitable MIDI connection, onwards to other external MIDI devices). As the data passes through Midiflow, you can both monitor it (to see what data is actually going where) and modify it (change the values in some way whether that is to remap them or to filter/restrict them; there are plenty of options and even more via the two additional IAPs). In addition, Midiflow can act as a MIDI Clock source and, providing you can get your destination app hooked up OK, you could therefore use Midiflow as the clock master for your various other iOS music apps.

If you do like to work with multiple iOS MIDI apps – and in particular if you do that in a live performance context – I can imagine Midiflow being a very useful utility app to have around. The performance also seems very solid and, as a useful MIDI utility app, Midiflow has a lot to recommend it.

    1. Theres a bug in midiflow where you cannot connect two identical midi keyboards (roland a49 in my case) as midiflow is not differentiating them based on usb port, only name. Hopefully johannes fixes it soon! In the meantime its midibridge for me.
