I am creating my own midi-instrument and would like to know how to create a PC driver program for this instrument. Does anyone have any pointers or resources I could look at to help me complete this task?
All i have found so far is
1) https://msdn.microsoft.com/en-us/library/windows/hardware/mt187811(v=vs.85).aspx --> USB drivers
Check out the Driver samples for Windows 10. The Sample KMDF Function Driver for OSR USB-FX2 might be closer to what you need, if you want to write a USB device driver.
Just make your device conform to the USB MIDI device class specification, and you do not need to write any driver for the PC.
