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.
How is Audiobus 3 different from AUM?
The feature that people seem most excited about is MIDI routing. But AUM already has a version of this. How is AB3's different or better? Is it the slot for MIDI effect/filter apps?
Are there other features that distinguish AB3 as a host environment? I do see some advantages for quickly restoring complex app setup. But these, to me, have to be balanced against more flexible audio routing and effects in AUM.
I'm not posing this question to criticize the new app or its pricing. Both developers seem friendly with each other, and I'm not interested in stirring up idle antagonism. But the new app seems to compete with AUM in a more direct way, and I'm trying to grasp what it offers before I invest time and music in it. That, to me, is more valuable than US$10.
