French VI manufacturer UVI showed us their Orchestral Suite - which provides over 60 orchestral instruments in a compact drive footprint. The total download is a mere 4.2GB
it uses the UVI Engine, rather than the usuall Kontakt based intruments and features their own Convolution Reverb for added ambient realism.
I dont think the MESSE show floor was perhaps the best place to hear the nuance available with this library, there's a great set of demos posted on the product page at UVI.net too.
