First of all, love your Superior Drummer 3 product, both the SDX and EZX lines.
But maybe its time to make another approach to the expansion lines since its very much the same.
I like the idea with the famous producer expansions, but what about making expansions with famous drummer?
GGD drums has just done it with Benny Greb:
Benny Greb Signature Pack
And its a great idea, since a lot of famous drummer has a very recognizable sound. eg. Dave Weckl, Simon Phillips, Peter Erskine, Benny Greb, Steve Gadd, Jojo Mayer, Vinnie Colaiuta, Steve Jordan etc.. the list is long.
invite them into a studio, and let them play on their normale kit.
I know you have done a EZX expansions with Ash Sloan, but that is as a producer, and actually its not the same sound as if you hear him play in his studio on several YouTube clips.
Just my 2 cent😊
