Although I haven't been a very active member of the VSL forum but I just wanted to back up a lot of the posts I've seen here regarding the upgrade path decision, which I think is ridiculous, as many other users also have. I "invested" in the Pro Edition and Performance Set way back in 2004, and I also believed the promise that this investment would last a "lifetime", which turned out to be a lie. Whatever else has been said in previous posts I do not personally trust a company that has blatantly lied to me, and therefore will no longer be purchasing any of their products ever again. The photocopy of the original manual (from Mobius' post) which I own (and stupidly believed!) really sums up the whole matter as far as I'm concerned. I now feel ashamed that my investment (which, in a very patronising fashion, certain senior members of the forum claimed wasn't even supposed to be an "investment" after all!) has enabled VSL to expand as a company and then do this to their loyal customers. I am very suspicious of the motives of a company which would do this sort of thing, and it seems to be purely for financial reasons.
I was quite excited by the VI libraries when they first came out, and I listened critically to several of the new demos which were made using the new libraries. However I was a little disappointed in many cases, as to my ears most of the demos really did NOT sound any better than some of the fantastic demos made with the original Pro Edition and Performance Set (the overriding factor is obviously the musicality of the arranger, rather than the sheer number or format of samples he was using, or whether he was using the latest version of the sample player). This is mainly what discouraged me from spend 1000's more on extra samples and the new sample player, rather than financial reasons. Now there is even less reason to even consider "investing" in VI, due to the large extra costs that would be involved unless I go for the new libraries pretty much immediately, before the deadline!
I know that the VI technology has been around for 2 years (which incidentally was also pointed out in a very patronising way by another senior forum member), and I was seriously considering upgrading at some point. The technology and number of samples is increasing all the time so it must have something going for it (I'll admit that!). However I certainly will not be doing so now, and I don't want to have anything to do with this company any more. There are many alternative options which perhaps aren't as comprehensive as VSL as a whole, but gathered together there are many other viable and interesting ways to expand your sound palette which don't involve helpling VSL to achieve a monopoly over orchestral sampling which they are clearly aiming for. I hope other users come to the same conclusion, nice work VSL for alienating loyal customers.
