Anyone using this? It's a free drums VST, and whilst the world isn't short on virtual drummers, what I like the look of is the integration of beats and fills. Each beat is automatically linked to a range of matching fills. The video on their home page looks impressive. Especially for donation ware.

For free it's excellent. Much beyond the sounds out of my old Roland keyboards.  Some of the MIDI is good as well.  I've layered it with other VST and that's been interesting

I use this quite a bit.
I also have Superior Drummer 2.0 and AD2.
I like the ease of pulling it (MT PowerKit) up and getting it going fast, along with the basic solid drum sounds of the kit.
By the way for a donation to them for a minimum of I believe $9, you can skip the initial load message. It's a great product, and I find if to even be worthy of the donation.
IMHO
