About the VST plugins..
To many people make mistake, they think that is the MS OS that have to loading the VST plugins, this is Wrong!
Read again the VSTHost manual.
The MS OS will ONLY run UP the VSTHost and make the all audio midi connections automatically.
On VSTHost interface you have then to load the desidered VST Plugin and SAVE the Performance. ( Save on VSTHost!)
On next restart players, the MS OS will scanning again the all VST Host programs performance saved and you will see on MS display.
The all VSTHost features are made UNDER VSTHost interface and NOT on MS OS side.
This is written on Manual too.
