Norman, thank you. I was unaware of this app, and it seems quite useful. But before I spend $30 for yet another app, I have to be clear that this will do what I need:

1: create the iReal Pro chord sheet..
2: Save as MIDI to another app, as it will not save to iReal Pro. For reference, I use GoodReader
3: Connect via USB.
4: Run Disk-Aid and it will allow me to navigate to my midi file even though it is not visible in the iTunes->device->Apps-File Sharing window.

If that is correct, I'm in!
