I'm shopping for a virtual piano instrument. One of the key (ouch!) parameters I look for is the number of velocity layers the sample library contains for each pitch. There's more to it, of course; the tone and timbre of each pitch shouldn't change dramatically with each change in volume as the instrument transitions from one velocity layer to the next, but in my experience that problem usually decreases as the number of velocity layers increases.

The question is, how many velocity layers are in Garritan Authorized Steinway?

My apologies in advance if the information is contained somewhere on the Garritan website. I read all the Steinway pages, but couldn't find it.
