Warren,

Out beloved Band in a Box can still only address ONE MIDI output port at a time.

So you could change the channel assignment, but it would still be headed to the chosen output port, such as the DXi.

You could use the VW with a hardware synth, though, by daisy chaining it after the synth and then going into the menus of the devices, disable that channel on the hardware MIDI SYNTH and enable that channel on the VW.

There also may be ways to use software MIDI cable or yoke to run the DXi synth plus the VW, as well.
