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.
OT Beatstep pads
I am about getting an Akai mpd218 ,but looking at Beatstep (which has 16 encoders) I was wondering about the pads quality. Can you hit them hard without feeling you reach the plastic bottom ?
I had the trigger finger pro and although the pads where soft ,they didn't have much height and on hard hits I felt hitting on metal covered with silk...(hope you got it!)
