Hi guys
I have this issue, Midi communication is getting lost not only to Cubase, but to any standalone instrument in Win 10 64 bit.
This used to happen very seldom in the past, and the remedy would be to restart windows.
Yesterday I installed an M-Audio Oxygen 61 generation IV keyboard, and it seems to happen all the time now.
After a while, there is no midi input and I have to restart Windows to get the midi communication back.
Any ideas???
