EXS 24 Logic Sampler Users Group

I'm very late to the party on this, but thanks to the 
about-to-expire-too-good-to-refuse upgrade offer from Vienna, I 
upgraded from my variety of Horizon Series EXS24 sample sets to the 
Special Edition and SE Extended version. I'm now kicking myself for 
taking so long to make the change. It's a slick and intuitive 
interface, every function that was previously part of the EXS24 
programming is streamlined and efficient, and many things that I 
would previously avoid altogether (or at least dread) are now a piece 
of cake. Having all the string articulations on a single track will 
make score creation much easier. This is one impressive piece of software.

I haven't completely torture-tested it yet, but it appears by way of 
the Activity Monitor that the Vienna Instrument uses its own shell of 
sorts, and adding more instruments has very little effect on the 
amount of memory Logic is using. As I'm still on OSX.4.11, Logic 
7.2.3 and a G5, I'm sure there is still a 3.5 GB limitation on a 
single program, but I'm wondering if Vienna can load that much 
independently of Logic. Has anybody tested this?

On that note, I caught on the Vienna Forum that people using the 
Horizon Series are having major problems with the VSL Performance 
Tool and Logic 8. Any corroborators?
