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.

Bad midi cable
If you ever heard a midi cable could be bad. Then here it is. Needed to qualify for free delivery so bought these ( instead of van damme ) or other. Added a van damme when setting up a faderfox and it fixed issue. Thought id bought a dodgy faderfox from a while back but it were a the cable.
You can see it not being able to transmit midi.
