I posted a full review of Audiobus 3 just after it launched. One of the key new features of Audiobus 3 is MIDI routing; as with the audio routing options that Audiobus originally made its name with, the new version also allows you to route MIDI data between sources and destinations. This is a cool new feature and I’m sure will help a lot of iOS musicians to make a little bit more sense of these ‘virtual’ MIDI connections.
As I also mentioned in a post, a suite of 8 MIDI utility apps from developer Johannes Doerr appeared at the same time as AB3. Johannes is the developer behind Midiflow which I’ve reviewed previously here on the Music App Blog. It’s a very useful general MIDI utility and has had regular use here at Music App Blog HQ over the years. These new apps offer the same sorts of utility functions but each is targeted at a specific task and all are designed for specific use within Audiobus 3 which acts as a host for them.
Of course, you can only use these MIDI apps with other iOS music apps that have been fully updated themselves with Audiobus 3. At present, that’s a relatively modest (albeit growing) number. Apps that are still just AB2 ready, while working well enough in terms of audio routing within AB3, can not make use of the new MIDI routing features….
So, in the meantime, you might be interested in the latest Midiflow app – Midiflow Adapter – which launched on the App Store later yesterday. Again, this is designed for use within Audiobus 3 but it allows you to access some of the new AB3 MIDI routing features even with apps that are not yet themselves, AB3-ready. Johannes is keen to point out that not all AB2-ready apps will work with Midiflow Adapter – it depends upon how well MIDI connectivity has been implemented by the app’s own developer and Core MIDI is then converted to the new AB3 MIDI system – but many will and Midiflow Adapter therefore provides an interim solution for those already finding AB3’s MIDI routing useful.
Anyway, as you can see from the screenshots and the demo videos below, an instance of Midiflow Adapter – which can be placed into either a MIDI input or output port, then provides you with ports for up to 10 target apps (synths, drum machines, etc.) and 10 source apps (a sequencer for example). And, if you want more, then multiple instances of Midiflow Adapter can be launched within a single Audiobus project.
I’ve only had the briefest of time to try Midiflow Adapter as yet but my initial experiences were positive. Yes, there is some configuration required but, if you are starting to like the MIDI routing options that AB3 offers (and these can provide some interesting creative options), then the UK£1.99/US$1.99 price tag for Midiflow Adapter is more than likely going to be easy to justify. Of course, we would all like to see every popular iOS music app support AB3 (and AU come to that) but the reality is that that is unlikely to happen and we are likely to have to deal with ‘legacy’ issues for some time. Anyway, until I can get around to digging a little deeper, check out the videos below and then hit the download button to find out a little more via the App Store.
