This can be used for a user-mode MIDI driver creation (the guy there used it: https://coolsoft.altervista.org/en/virtualmidisynth)
Any examples of it?
How to register the driver? I found VirtualMIDISynth under HKLM->SYSTEM->CurrentControlSet->Control->Class->{4d36e96c-e325-11ce-bfc1-08002be10318}.

Yes, but it doesn't say how to register the driver to the registry.

In winapi Installable drivers, Its function is to connect with the standard drivers. it can not create user-mode MIDI driver.

The link above shows a user having created exactly that, a user mode midi-out driver.
