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.
(Drambo) 8+7=15 : A THING OF BEAUTY
Just wanted to share this setup with you all. I don't know how well things will hold up CPU wise, but the fact we can do this with Drambo just excites me. This setup will work great if you have some hardware synths, just point the Midi Channels to those pieces of kit.
Thanks again @giku_beepstreet for this vision of yours which you so willingly shared with the rest of us.
Let's see if this share works for the AUM file:
