Bells, Whistles, and Sound Boards is a
new programming library for adding 100%
digital music and sound effects to your
own games/demos/intro/etc. All routines
are written in optimized 386 ASM. There
are *no* registration fees for freeware
programs. Fully uncrippled release ver.

Lots of stuff in the zipfiles. The gdmkit has a mod>gdm converter but not the other way. I have a few gdm mods somewhere, they all look like converted protracker. Not sure if these are what your looking or if they are anything to do with the gdm format.
Attached is also a gdm file spec or something.
