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.
Best way to "DJ"?
Ok, so I guess not really DJ. When I play shows, I usually take 5 stems of my songs (drums, bass, leads, vocals, fx) and trigger them at the same time in Ableton, adding fx, doing live vocals, and riffs with a sampler or synth. My laptop no longer runs Ableton reliably, so for a while I was using an Octatrack to do it. I've sold the OT, though, and now need a replacement on my iPad. I'm not a DJ, so DJ software is mystifying to me and I'm not really interested in learning to DJ. Any ideas on a good app for this kind of thing? I've considered BM3 and pad launching, but that thing crashes more than my drunk grandma without her glasses.
