I bought an app that turns my iPhone into a mod wheel so I can have a wheel for my Yamaha keyboard. Unfortunately, I am unable to use it because I can not get my iPhone 4S to be recognized by Midi Network Setup up. It should appear automatically in the Directory window but it does not. I've restarted both my iPhone and computer but that has not helped. My phone is sending and receiving wireless/bluetooth so I don't know what the problem is.

Any help anyone can give would be HUGELY appreciated.
