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.

Would it be possible to create a Forum "Category" that is specifically Apps on Sale?
Anytime something goes on sale, it's been going in the GIANT "Everything is Cancelled" thread but that covers so much meta-discussion as well that I often miss those posts.
Unrelated question because if this exists I am clearly an idiot - Is there a way to jump to the "most recent comment" on any thread instead of clicking the link to the very first post and then clicking the bottom breadcrumb to get to the most/more-recent?
