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.
jam along youtube videos
i can't find a way to do it so here's my post : is there already a way (or can you make it ?) to jam along a youtube video and record it (i've got beatmaker) ? i play in a cover band and this would really be helpfull between all band members (choosing tracks with personal lines on it, exchanging ideas, ... without having to convert each track first on a pc, then get back to the ipad, etc...). Thanks !
