I have just sent off an email to IK Multimedia suggesting they perhaps get their apps JACK'd
I also sent it to Unrealbook developers too, as MIDI "control and setup" files cna be linked to charts, songsheets song guides etc within the app. Imagine, open the running sheet on Unrealbook, and instantly have the synth/s set up with the right pre-saved program/performance!!
Web address is: http://www.crudebyte.com/jack-ios/ and they reckon it only takes about an hour for developers to get an app registered to run with it, and is free too I think.
Anyhoo, just a heads up for those who had not heard of it
