Coyote
Forte is a 32 bit sound module that you must purchase. The reason why you must purchase it is because Forte includes unique instrument patches.
Coyote
WT is also 32 bit but it uses the standard Windows instrument patches.
Edit (Andrew - PG Music): there is also a 64-bit Coyote WT.
PG Music packages two midi sound modules with Band-in-a-Box (2019), the Coyote WT (64 bit and 32 bit), and 64 bit VST Synthfont 64.

VSTSynthFont64 Included
The 64-bit version of Band-in-a-Box® allows you to use the VSTSynthFont64 as the General MIDI (GM) synth. With the VSTSynthFont64, you can specify any GM soundfont or DLS files, including larger ones over 2 GB.
