Ok, so when you mention 15 to 20 instances, what does this imply exactly (sorry I'm not familiar with PLAY at all)? In other words, is it something like this: Violins 1 and all of its art's in one instance of PLAY? Also, 15 - 20 instances uses how much RAM on your system?
To add: how does one go about switching between patches within an instrument articulation? Does it use keyswitches as well? For example: going off a demo vid, let's say you are in 1st violin, short tight.I see there is a Xfade patch for Spiccato to Marc and another patch below that Stac to Marc. So how would you switch within a composition?
Yea loading times I suppose are the trade-off for certain libraries, depending on the size.
