There is some info here:

Band-in-a-Box will send some sync info, if you go to Opt. | Preferences | MIDI Options, and check "Output Sync/Start info". It will send MIDI clock, and song start/stop messages. It doesn't send MIDI Time Code, and you can't use it as a slave (i.e. it won't respond to sync info from another MIDI device). RealBand on the other hand has more advanced MIDI sync capabilities.
