“Does anyone know if this works with an electronic drumkit (I have a KAT KT3 that works nicely with EzDrummer) and I’d love to get some Simon sound out of it. I can’t find ANY information about this anywhere, which is weird.”
This is the first comment/question on Youtube (“Introducing Simon Phillips Studio Drums for Groove Agent” - Steinberg Channel)
I tried to answer and guess what? My answer does not appear. And absolutely NO comment by Steinberg regarding the comparison with Toontrack except " Unfortunately good sound is always expensive on the CPU "…
Actually it has to be: Unfortunately bad programmed VSTi’s are always expensive on the CPU 
And no comment on the eDrum features (like variable Hihat).
Hey Simon, if you read this pleeeeaase comment on the bad/missing eDrum features and the CPU issue.
Can you imagine there are musicians out there who want to play eDrums with your great sound? Don’t you feel sympathy for them?
