I think you're still not clear on how to set up a standard template. Some people, myself included, would use VEP5 to do that since it helps manage various things and also plug MIR into the end result, so let me speak in those terms (sorry if this adds another bit for you to consider, that is VEP).
On one single instance of VEP as your host, add 8 VIP instances, and add each one of the individual DS violins to each VIP. So VIP1 will play DS Vl1, VIP2 will play DS Vl2, etc. So you have 8 individual players for you to write for as you wish, each routed to a separate MIDI channel. Now, on your DAW or notation software you replicate the setup, and have 8 separate staff parts. Unison play? You write once and copy+paste to all parts. You want Div2, write the two different lines on Vl 1 and 5, copy/paste 1 to 2,3,4 and 2 to 6,7,8. And so forth if you wanted other divisi configurations. So that takes care of your first 8 violins. Hope that's clear.
This is not extremely CPU or disk intensive, but it does take much more computer power than most other libraries, as in the end, DS is comprised of a set of individual instruments, just as if you had 8 instances of the Solo Violin playing simultaneously. But I don't want to digress much.
Now for your second group of 8 violins, you have a few options. First, what has been mentioned about detuning and transposing another group of individual violins just as above. Second, could be for you to utilize the desks or 4-player presets included in DS by VSL. You could set up the 4 desks and the 2 4-player groups and use different humanization parameters, and use different EQ settings, to make them sound slightly different to the individual violins above. Then on your DAW, you'll include separate staff lines for each desk/choir, separate MIDI channels, and write there whenever you need to.
In the end, the most you'll have is one VEP port, with 16 MIDI channels / 16 VIP instances (or less if you use the pre-mixed desks), for all your complete 16-players violin section. Then do the same for the Cellos, etc.
This is what I do, and I didn't win the lottery... yet.
Hope this helps.
