I have a workaround for this...I use Midi-OX (freeware) and map the output of my synth keyboard to the input of the BSP through a MidiSport hub. The synth goes directly to my DAW (or to another synth chain or...). I can then route the three channels (1, 2, 10 for simplicity) of my BSP to a DAW or chain of synths or other combination and use the the receiving device to sort it out (this works best with a hardware synth or a DAW where you can set the channel). Unfortunately, most software synths don't let you filter channel numbers, so you can't use them unless you embed them in a DAW or use another channel filtering scheme.
