Missing percussion on Sounblaster Pro... MIDI?

[HMPoweredMan]

Cymbals and snares are not audible on the current build.
The best example I have of this is Super Solvers: Treasure Cove
Here is how it should sound. https://www.youtube.com/watch?v=GhHqGp_tmBc
compared to
audiotest.zip

I am using the default settings A220 I5 D1 T4. The same issue was prior to installing SBPro driver on the image.
This seems similar to the issue reported in this thread.

I just want to clarify this applies to all soundblaster configurations

SB
SB16
SB Pro

It is my understanding that this applies to adlib specific audio. Missing FM operators?

I did notice that in the SB sound test software that 4 operator synthesis was not working while 2 operator synthesis was. Perhaps unrelated.

Also tried on OPL2 and OPL3 same results.
I'm just a lamen so my terminology may be off but just want to make sure the full picture is painted and this one doesn't get overlooked.

AFAIK drum mode is not implemented in current OPL2/3 emulator.
