I have yapped for a long time about making a replica of Altered Beast on the Mega Drive, and allow myself to spice it up a bit with sampled drums while I was at it, as well.
It's simple: I can't replicate the timpani. And this special channel 3 feature has also been used for the timpani in Golden Axe and Tetris.

I can't make it for certain that all three games use the same channel 3 settings, but I can tell by ear (or at least so I believe) that in all three games the timpani has a particular timbre that you can't get by merely modifying multipliers.

I tried converting one of the VGMs to text using VGMTool, and while it's really detailed, I get lost and I don't know where to identify what channel 3 is doing - what note is assigned to each operator.

Does anyone know how to do this?

Have you tried using LFO or SSG-EG? Fine tuning the pitch with E5 can also help with some percussion sounds; I had to use that for a Valis 3 cover for example to adjust for DM lowering the overall pitch of everything.

It could also be sounding a bit different due to emulation, I don't know of any real hardware recordings for AB.

Edit: I think they use LFO for the snares in those early games, I remember it sounding different in VGM MM when covering some GA1 tracks. That timpani isn't super great though, so maybe you should just sample one or use one from Gauntlet IV instead.
