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.
Beathawk - worth another demo?
The forum has a lot of strong opinions on things. I'm planning to create a video on BeatHawk and what I like about it and some tips about using it that I feel haven't been covered in other videos. There's a lot of competition out there for sample based apps like BeatHawk, so is there anything that you think I should cover specifically and alternatively, anything that would make it not relevant - for example another app that you think offers similar or better features at a better price?
