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.
Getting rid of the spam
I believe that recent versions of Vanilla forum have a Troll flag that can be set by moderators and admin.
This has the effect of allowing a user to post and see their own messages, along with all the other posts, but nobody else on the forum will see the posts from that user. I propose that this would be an effective way of dealing with spammers such as the movers and packers and shoe salesmen, since they would not know their posts are not visible and would therefore not be motivated to keep creating new accounts for their spamming activities.
