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.

BM2 and Sampletank working together
Since the audiobus update to BM2 I noticed that Sampletank can work at the same time as running BM2. Before they would never work together without the sounds getting feedback regardless of the A or B dock combatability setting in ST. Now with the B setting set I can control/arrange in BM2 out to ST. That's up to 4 channels of VST like power for both drums and synths. The AB update to ST will even streamline the workflow even better. Just so glad I can finally use these 2 without the sound losing quality. Using a 4GS btw
