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.
To Devs: Support Audiobus – Sell More Apps!
I wonder how many people have purchased apps BECAUSE they were the first, early ones to offer Audiobus support? I bet the number is high. I purchased two apps that I didn't previously own based on the fact that they were ready to go with Audiobus from the start. I'm thinking that immediate adoption of Audiobus would produce a lot of sales for developers savvy enough to realize this... Thoughts?
