I checked both the Sibelius and Garritan sites and can't find any updated info on the product. Do any of you know if it works with Sibelius 5 and Vista? (only Sibelius 4 and up to Windows XP are listed on the page above).
The crossgrade was for Sib 4 - it allowed Sibelius to talk to GPO. If you have Sib 5, all you need is GPO, no special editions, crossgrades, etc. There is a built in soundset that translates all the keyswitches - arco, pizz, etc, to work upon entering the text.
