This is one of those "I Can't Believe it's Free" instruments. I was really impressed with the authenticity of this instrument even in it's early beta version, and the final release just added to this favorable impression. I've never played a real D6, but have heard them in countless records, and this recreates that sound extremely well. Just to put it through it's paces I grabbed a midi of Stevie Wonder's "Superstition" and ran the output to TrickyClav and I just have to say how great it sounded. The wah/effect section is a nice bonus too. I'm sure that some Clav purists who own a D6 would find something to nitpick over this instrument, but it's better than the clav samples I've come across so far. If you're into classic keyboard sounds and need a clav to add to your collection, this is it.
