You don't need to apologize, Bill.

I can only speak from my own experience, but I must admit, I'm very happy with the kits on my Tyros4.
I've been doing a fair bit of home recording lately, and the Tyros4 is one easy instrument to work with and I get a very nice finished product, indeed.
These BFD drums sound rather good, but VST's aren't my cup of tea.
Do you use these kits in your trusty old Abacus?
