I can load up more instruments per VEPro instance. If you want that you can play every instrument with seperate midi tracks you have to load the VEPro instance with the server interface VST in the VSTRack and set the midi and audio ports right (cubase and VEPro instance). If you use it in a instrument track you can still put many different instruments together (like with Kore2), but you have only one midi control track, ie ist not multi. And all instruments will play together.
Right click in the VEPro instance (VSTRack->ServerInterface->VEButton(master instance)) and select "New VSTi" then set up the midi and audio channel in VEPro.If that instance is on a slave (mostly it will be this way) you have to do this on the other computer(slave) because you can't control the slave instances from your master computer, setup is still the same.At last you must set up a new audio channel in the cubase VST rack (that you set the new vst to) and create a new cubase midi track set to the corresponding midi channel in the VEPro instance.
So you can load K3.5, Kore2, Sylenth1, another K3,5, VSLInstrument all in one VEPro instance for example and play them with different midi tracks and output the sounds on different stereo output tracks.Auto connect dosen't work, unfortunately we must reload the plugins in every VEPro instance manually (click on the arrow "load plugin data" it's fast so not that big deal). I'm not using the VSTPro server windows (though they must be running in the background) but I'm loading everything directly from my cubase projects. So I have to reload all VEPro instances manually. Hope that an automatic function will be implented in future versions!
