So far I'm having to load a new instance of VE PRO on the slave per VST I'm adding, and for the life of me I do not see the option to select a port on the MIDI track. Just the basic 16 channels.. (port 1)
I'm hoping that I'm overlooking something and this is not just a limitation of Sonar.. I know of freeware such as Maple MIDI and the like. Unfortunately none of the available options seem to be compatible with Vista/XP 64 bit.
