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.
Marking/noting forum threads
As we build the wiki, I'm thinking that it will often be worthwhile to add wiki articles that point to individual forum posts or threads to help people find some of the hidden gold -- even if we don't have time to write up a nice new article.
I am not sure if people realize that each forum post has a permalink that you can copy. If you weren't aware of this, the time/date that appears at the start of each post is a link to that individual post.
It is also a good idea when quoting from forum posts to link to the post.
