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.
Vector or bitmap graphical assets for iOS music app?
I've finished developing an iOS app (my first but I've developed many other things on other platforms) but so far it only uses placeholder assets for all the graphics.
For a photo-realistic or skeuomorphic look on iOS, do designers use bitmaps or vectors?
I'd be interested in hearing from (or be given details of) any designers experienced in this area (graphic design for mobile music apps).
