As Jon suspects, I used the Kirk Hunter Solo Strings for this piece (and nothing else). The spiccato release trigger samples for the violin, viola, and cello are used a lot for the fast runs.
The repeated notes are the release trigger samples. These are programmed with a lot of velocity layers to them. The violin solo is a combination of the basic violin program (Spiccato-detache-hard sustain-expressive legato whose articulations are controlled via the mod wheel) and the up down spiccato trigger release sample for the same instrument. I used these combinations of articulations to lend variety to the repeated notes. But it is really the up-down trigger release samples that I exploit in this piece.
Yes, but I think it might be a subset. As I recall it's a good sized subset. The intent is that it's all you need. It's not intended to be a teaser for KHSS. I could be wrong about the subset thing though.
Kirk's Concert Strings are definitely on my short wish list. Money, money money...
