Midi Vst issues

My Roland keyboard suddenly not working in midi , When I open it up a VST no sound.
I checked the inputs and outputs everything seems to be ok . but no sound when I try to choose a piano sound on my midi vst. If I put my curser on the piano on the screen it works… but not on my Roland.

Hi and welcome to the forum,

Make sure the Roland Input is not in use as any Remote Device Input. Or the other hand, make sure it is in use in the All MIDI Inputs.
