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.

The new update to Sampletron by IK Multimedia contains tons of grungy new presets, and here you can hear me demo them all, albeit, generally with my own little tweaks. I added a little external reverb (FAC Alteza), even though Sampletron has its own reverb, because this helps ameliorate the slightly unpleasant gap that occurs when you switch between presets.
PS My Giveaway for K-Devices, Bram Bos and Bleass apps still has a day to run at the time of writing.
