    USB MIDI Jack Configuration

      Hello folks,


      I've been working on getting a modified version of the USB MIDI 2x2 example project up and running. My goal as of right now is to simply add an addition port to make it a 3x3 MIDI interface with both an internal and external connection.


      So my main issue is the lack of documentation on configuration of the MIDI IN/OUT jacks in the USB macro. The component datasheet gives lots of good info on the descriptors and other USB configuration setting but almost nothing on the MIDI Jack configuration.  


      Here are the parameters i'm talking about


      bJack Type - This is simple, EXTERNAL, EMBEDED, or UNDEFINED


      bJackID - Also straight foreword, ID for each jack in the design 


      bNrInputPins - Have no idea what this parameter is for


      baSourceID - No clue on this parameter either


      baSourcePin - No idea on this guy either


      iJack - The String name for the jack


      Can one of you smart folks shed some light on what each of these parameters is for so that I can configure it properly?
