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.
Can You Develop iPad Apps on an iPad?
Can you develop apps for the iPad on an iPad? I've looked at the Apple site and it seems like you need a Mac to do development work for the iPad. I have no intention of buying a Mac and it looks like PC emulators aren't supported. I don't have any grandiose design plans for an app. I'd probably get bored soon after my "Hello World" program. It just seems odd to me that there don't seem to be any iPad code compilers or screen design tools available for the iPad. Is the iPad processor still not powerful enough to do development work on using the iOS SDK? Just wondering.
