patch assignments in BIAB show the GM patches by default... but actually patches are just called by number.

The patch list in the manual shows them in the numeric order you would call them.

So to call the first patch (HIT VOCALS) select the first GM patch (acoustic piano),
to call the the 11th patch (FAT LEAD+3rd) select MUSIC BOX (the 11th GM patch)
to call the 35th patch (3 BELOW) select PICKED ELEC BASS (the 35th GM patch)

I think you can actually make a patch list so the patch select dialog box shows the voiceworks patches by name instead of the GM patch names, but I usually just use the manual's patch list as a reference. I find myself using the same favorite patches most of the time, and I just use CC to change the key and harmony type.
