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.
What’s your local app store return policies?
Here in Norway we can refund any apps for no reason at all within two weeks. This helps immensely when establishing a library of quality apps that work well together. Any problems and app not in active development = return and refund. Probably have done this with half my purchases. I always try to check with the developer if it might be an easy fix, as there’s a reason behind my spending.
Also interested in knowing how this affects income from a developers perspective.
