[LAU] What kind of sample(er)s etc for classical music

I'de like to have some info/pointers on samples for classical music (especially orchestra) in the situations when one has to provide a 'virtual' performance. There are plenty of synths and stuff done with linux for linux, I myself use puredata extensively for electionic music, but this is a different dcenario. I've lately tried the linuxsampler stuff (qsanpler etc.), and was impressed by the freebie gig piano on the website, but it looks the gig format is quite dead at the moment, I wonder if there is a second hand market for those, as it looks they were very popular before tascam closed down the gigasampler thing. For classical music, searching around it seems that currently SoundFonts are the best supported form of samples on Linux. I'm not necessarily talking of free stuff: quality sampling is a laborious and skilful process and paying for good samples is fair enough for a (digital) musician, so I'm talking about support: in fact it seems that most packages are stand-alones for windows or mac. Best regards, Lorenzo.
