Hello,
best experiences I got with VirtualMIDISynth from Coolsoft (
coolsoft.altervista.org/en/virtualmidisynth).
That is an user mode multimedia x86/x64 driver that works on Windows XP / Vista / 7 / 8 / 10 / 11 (both x86 and x64), implemented as a MIDI Out virtual device. Select it as output on your preferred player settings and... start playing, nothing more.
