Hi Bob ! Hey I also use Steven Slate drums , which version are you using and what are you triggering your Steven Slate drum software with ?
I have to use Addictive Drums that sort of works , it doesn't trigger all the drums mostly the Bass drum and Snare .
The drum mapping isn't right for that software in Addictive Drums , right now I'm having problems activating my product with ( Native Instruments ) .
I hit the activate button after I installed it and it took me to their web site , problem is I have a different IP computer number now that I'm using my new PC .
I contacted support and gave them all that information , hopefully after the holidays I will hear from them so they can update my online information so my software will work as a full working version not the Demo version .
Happy Holidays Bob !
James
