With the song playing, solo the track you are working with and the 'number' of the port that is assigned will be flashing in the left panel of the ST window. There is also a chart in the BIAB documentation that provides the midi port assignments in BIAB. For instance, 5 is normally the Thru-channel. The port may also be listed if you open the Right/Click menu of the BIAB track.
