I am not sure what effect any song setting (ALT F2) will have on the default mix. In any song you can set values for pan, volume, reverb, and several others.

I know I tries to sort out the precedence of the default mix, the song settings and the style, which also has similar settings.

another one of the quirks of BIAB - multiple places to achieve same / similar results.
