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.

Making coffee and preparing to watch it!
I hope it makes sense
Doug, makes perfect sense. When you flipped to the full session screen at the end, it immediately presented itself as ios Ableton/Bitwig.
Looking forward to setting up a session with my iconnectmidi4 and a few hardware synths and a drum machine just to see if I can make it all work.
Thank you sooo much for your wonderful tutorials. Looking forward to your next modstep tutes'
Been a long time in coming Sir Doug, happy it's here

Thanks Lord Johnny, I made an error also, the fact is you can import your own samples in via AudioShare, which is just mega
