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.
External Monitor Suggestions for Macbook
As my studio expands — which is dangerous and not glamorous, I say to all who exist solely on iPad! — it occurs to me that the 13" Macbook Air is not enough.
For whatever stupid reason, the various defunct iMacs around the house can't be easily cannibalized for their perfectly good monitors.
So what do I need to know before I buy? The laptop has USB3 and Lightning ports. I don't need anything huge, and I really don't care about screen quality (at least I think I don't). This is for Ableton 90 percent of the time.
