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.
SOLVED: Let loaded plugins control Loopy Pro actions (via MIDI)?
Is it possible to let a plugin trigger and control Loopy Pro actions to get some kind of automation?
AUM has that useful virtual “MIDI Ctrl” interface. Any plugin can send MIDI data to it and control the host and other plugins parameters.
Currently I was only able to achieve this by using an external app to connect the output and input of Loopy Pros virtual MIDI interface. But I wonder if there is a simpler way.
To answer my own question: Yes, this is possible!
Open “MIDI Learn”
Choose what you want to control
Then “Tap to define trigger manually” in order to choose the plugin or other source of MIDI messages.
Now you can configure type of message, channel etc.
