OK, I found the name of my favorite drum soundfont in my soundfont archive: NS Kit - I have several flavors of this one. The person who developed this soundfont sold the rights to it and now it is available for: $129!, when it used to be free, or at least a version of it was free. No free version any longer. You would be better off buying Jamstix and just using the samples inside of it while feeding it midi from your controller.

I also used a TamaRockSTAR.sf2 and a Yamaha Drums2.sf2 back in the day.

I'm not sure that this helps much to be honest, but I promised to look up the soundfonts I used to use regularly and as soon as I saw the names in my folder I recognized which were nice to use.
