Yes, rharv is right, Band in a Box can only handle one MIDI output at a time.

However, it is possible to use one of the free MIDI routing softwares in conjunction with Band in a Box, tell BB to route to the input of the MIDI routing software, then tell the software what to route and where in its multiple output selector.

It is very easy to load a bb song into Realband and select multiple MIDI outputs, though.
