After extensive searching, I find no list of notation programs and their versions that are compatible with the new GPO 4th edition. Not in any spec sheet I've seen, nor the manual at /products_gpo4.html. I'm trying to figure out if it will work with my Sibelius 4.1, because that will be my exclusive use for the sounds.
I've driven GPO with Sib4 since I was a beta tester for the GPO Sibelius Edition product. GPO4 will surely not work in the same way (I won't particularly miss Kontakt), but will it work at all and preserve the articulations, etc?
