I'm with fahl5 on this - the Synchron Player works so differently than VI or VI Pro that few of us have sufficient experience yet to express a deeply informed opinion as to the library's ultimate quality.
We do not have the experience but VSL should. By now, they should have many convincing audio demos to clear our doubts. After all it is their product. VSL should convince us it's worthwhile to spend the time and not wasting it. Apart from us being the early adopters who purchased the product purely out of faith in the VSL brand, I am sure they want to attract new customers as well.
The fact there is no convincing demo... it's already suspicious enough.
The fact VSL has been very quiet after last week release, it's even more suspicious.
Don't be surprised when they announce new product(s) in July... as a way to divert our attention.
