MIDI over USB

[RuudNL]

DaveC3, your code has been a great help so far.
Unfortunately, I didn't manage to get it working.
I suppose there is something wrong with my fuse settings.
Do you mind to give me your config settings?
(I stripped most of your code in the body, but the PIC isn't recognised as a MIDI device.)

[DaveC3]

I think I used a 18F4550 for this project. if you haven't already, I would suggest you first make simple HID project to see if you can get your PC to recognize your device. If you send me your e-mail address I will send you the whole project in a zip file.

Here is the .LST file for the project, you can see the fuse setting I used.
