If Microsoft's MIDI library is not detecting your pa4x (which is a common problem), then you are going to have to wait for the MIDI enhancements that I'm going to be adding after the library synchronization features are finished and released. I'm going to be trying to add my own library for MIDI communication over USB on Windows as Microsoft's library has some serious drawbacks and doesn't detect some devices. I don't know for certain that this will work yet, but if it does, there will be new options in the MIDI settings for connecting directly over USB instead of using Microsoft's library (which supports USB, bluetooth, virtual midi ports, etc). In the future, I could also try to implement my own bluetooth MIDI library if the USB one works well.

One possible option you have in the meantime to get your keyboard to be recognized is to have something in between the keyboard and your device, such as a MIDI to usb adapter (if your keyboard has MIDI out ports).
