Issues with MIDI settings
Quite often Musescore looses the MIDI settings, during the editing, or switching on/off the MIDI keyboard, the PC o simply restarting Musescore.
I tried with Windows 7, Windows 10, and MAC OSX with Yamaha, Korg and Casio keyboard.

Maybe solved in the recent development builds via the fix for #295443: "Toggle 'MIDI Input'" should reflect the setting of Edit > Prefecences > Score > Enable MIDI input on start of MuseScore
