Well, folks, it is very simple task to link VST-plugin and MIDI-output of any program.
1. You need a free program called MidiYoke. It gives you several virtual MIDI input and output devices. Every version of windows is supported, even Win 2016 Server TP4 smile
2. After that you set the MIDI-output of your favorite program to "Out To MIDI Yoke: 1".
3. You also need any of programs called "VST Host". "VST Host" from Hermann Seib, for example. Or SAVIHost. Or any other free utilities. This kind of "VST Host" programs can load VST-plugin and then you can set its input to "In From MIDI Yoke: 1".
