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.
Bias on sale
Bias is now down to $15 for the black Friday weekend. I don't really need another amp app, so I've held off so far, but i'm going to get it now. I'm also going to get a Griffin StudioConnect while they're on sale for $40 at Sweetwater. I don't need that either, but I can put it to good use. I might as well give myself some early Christmas presents for Thanksgiving.
