Check in SONAR again. The bass track should be the first one above the tracks for the other BIAB instruments.

What happens (and I don't know why) is that all the other instruments are created and named into their own new tracks, but the bass track, being the first in order, is inserted into the existing blank MIDI track in your default configuration and has that track's name. Thus, you might not think it is there.

Let me know if you find it, or not.

Which version of SONAR, by the way?

And the bass track isn't muted in BIAB, is it?
