MIDI Keyboard not advancing from note to note
I've just connected a midi keyboard to my computer for note input (very old beast - Hohner PSK60). When inputting notes, it won't proceed to the next note/beat when I press another key, but will just sit there adding more notes to the same beat, basically creating a great big cluster chord on one beat.
In real-time (automatic) the metronome doesn't sound and after pressing a note on the keyboard, it sounds indefinitely, adding more notes if pressed. The only thing which stops the indefinitely sounding note is quitting Musescore and re-opening (turning keyboard on and off doesn't make a difference).
Has anyone come across something like this before and would know how to go about fixing it?
Thank you in advance for your time.
