Say you have set a A-B change on bar 13 in the vst then the vst should play a pre A fill on 12 and a post B fill on 13.
But I don't think there would be any A-B in the Biab midi sync info, some VST's at the moment only receive Start/Stop message from Biab and no position/pause info like ReWireVST, TemperVST and others, that should be fixed soon as they work correctly in RealBand.
You may be able to ask Peter for some info to help so you don't need to enter the A-B B-A parts.
