USB Midi Keyboard not seen as a device
My Axiom air32 mini is not being recognized as a midi input. I plugged in the usb keyboard before Musescore was open, and the keyboard is certainly on, as the LED lights are on and responsive, but upon going to Preferences and I/O, the dropdown menu next to both midi input, and midi output are completely blank, and clicking on them doesn't yield a response. I am running the most current version of Musescore. Any help would be appreciated. Thank you for your time.
