Actually, it's on the Web! A friend of mine has it on is webpage:

"Primarily from a Yamaha TG-77 and a Roland JV-10, both rack mount. I really liked the Yamaha, such great, clear sounds with bite.
Digital Performer was, and still is, my DAW of choice.
I might have had Sample Cell then, but I don’t remember. I remember waiting five minutes for it to load 8 megs of samples!"
There's no such thing as a JV-10, maybe he meant a JV-880 (nothing JV-10** existed until well after this game). Parts does sound like early Roland JV to me.
Could have been a Roland D-110 as well.
I'm going to assume the TG-77 drums are what we're hearing in the Tetris track. Here's a sample of the patch I think it is:

D-110 drums, which I don't think it is:

JV-880 drums, which it could also be:
