At the very beginning of June of this beautiful year 2020, and following the last update of Windows 10 in version 2004, I had the unpleasant surprise to see my MIDI player using again the horrible “Microsoft GS Wavetable Synth” instead of VirtualMidiSynth.
It is quickly noticeable by ear, the MIDI sound without sound bank is quite unbearable….
A reinstallation of VirtualMidiSynth is not enough, you have to reinstall VirtualMidiSynth each time you reboot your machine.
Or more simply: go to the “Start” menu > “VirtualMidiSynth” > “VirtualMidiSynth Configurator”.
This one then detects that it is not correctly installed and then puts the MIDI driver back in place, but only for the duration of the session.
The developer has well identified and taken into account the problem on his site, but it will not be corrected for some time.
This is a change made by Microsoft in the Windows driver management.

Let’s hope that the solution will not take too long for VirtualMidiSynth users.
Updated on September 27, 2020 :
The developer of VirtualMIDISynth has fixed the problem with version 2.10.
Originally, it was not a bug, neither from VirtualMidiSynth nor from Microsoft, but from the way new versions of Windows handle drivers.
