Advice for creating a MIDI device out of HID reports

["Nguyen, Daniel" <daniel.nguyen.1@xxxxxxxxxxxxx>]

Good day,
I have a Mad Catz Fender Mustang Pro-Guitar for Nintendo Wii that was sold for the Rock Band 3 game. The guitar controller comes with a wireless USB dongle that is recognized as HID class when connected to a PC. The controller also comes with a MIDI port that requires a MIDI interface to connect to.

Since the controller comes with a way of communicating wirelessly and that have the HID reports figured out, I would like some advice about how to go about the implemention of a MIDI device. 

Would it make sense to create a MIDI driver which would convert the HID reports to MIDI outputs? 
Should this be done in the userspace or in the kernel space?

I have looked for examples in the kernel source but failed.

I appreciate the input. Thanks in advance!
