Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Bluetooth MIDI from iPhone to iPad via AUM
...vice versa, iPad to iPad, iPhone to iPhone etc etc.
Might be a game changer for me. AUM is my go to host currently and has been for a year or so but that is not without regret. For example, one thing I miss out on from Audiobus is the remote.
But setting up AUM as a bluetooth peripheral on one device to control AUM is beautiful. Its not the same as Audiobus Remote as I’m sending MIDI info rather than remote control of apps. But this is perhaps enough to fill that yearning.
So now I can play KB-1 on my iPhone wirelessly. Set up some Rozeta apps and sequence devices on the iPad. Things like XY and Scaler are very nice in this context. Autony could be awesome used this way too (once iPhone scaling is fixed), using Gestrument Pro’s pressure capability on a dedicated device...
The possibility is wide open and so far it runs smoothly without noticeable latency.
How to example :
To control Bram Bos’ app Troublemaker on iPad with another phone with AUM.
In setting up your send device (for this e.g. an iPhone) go into the Settings tab, scroll to the bottom to Bluetooth MIDI and touch Peripheral. Turn on to advertise your device.
Now on your host device (e.g. iPad) go into the AUM Settings and under Bluetooth MIDI choose Central and select your send device (in this e.g. the iPhone.)
Now, in the MIDI set up for your MIDI send device (e.g. iPhone with Rozeta Bassline loaded in AUM) go to MIDI Route and link the Bassline to the Bluetooth iPad in the Matrix.
On the iPad make sure that in MIDI Route you connect the Troublemaker from iPhone.
It should work.
Check all your MIDI channel stuff if its still not working.
