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.
FFS where are the acoustic drums?
I've chased decent drums since buying my first iPad. I'm sure it just comes down to taste but after today I feel like I've tried everything and it's all disappointing. About the best thing I can imagine is to build my own kit from samples (which I don't have) in Koala or similar. And I think I'm done with Lumbeats and anyone else who has stopped development short of auv3. (Disclaimer: All personal opinion, no facts were used in this post).
