Rikki, the system I was planning on using was Cantabile as the VST instrument "rack" and then tx the midi data from vA to it...

The plan was to set up various kits in the drum VST saved to it's patch banks (most VSTi's do rx program changes to select different patch slots) the same for the Bass VST and Guitar VST's...then simply assign a rx channel on each of the "racks" to the corresponding tx channel of the style in vA...all using software midi routing....

So in effect, apart from one midi cable in the rest is handled by the PC/Laptop...
