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? ------------------------------------
