if you qualitfy for the upgrade (i do), you can spend about 150€ and get 7.5 GB of samples from the VSL Orchestra:"A complete instrument set of an orchestra with 30 instruments, including special legato and repetition instruments, using the KONTAKT Script Processor "
since i think that i will go for the upgrade (although i have to verify that my p4 2.4 GHz is able to handle it...), i wonder how this sample collection is compared to GPO...
in a future upgrade will GPO make use of the kontakt script (which seem incredible, at least in words... )
Although I've mentioned this in another (Kontakt section) thread, it probably bears repeating here: Native Instruments (US) will let you update your Kontakt PLAYER (that which is included in GPO) to FULL Kontakt 1.5x for somewhere very near $229 and then upgrade to FULL Kontakt 2 (with all the extras included for a new sale) for (what was quoted to me) $89.
(There are some other numbers on the NI website upgrade pages, so there may be a $10 or $20 confusion here somewhere -- certainly nothing that would be a showstopper.)
This coule be an interesting option if you want to add a LOT of sample content and a full functionoing softSampler for around $330.
