Wow thats a great list. This will keep me satisfied for quite some time. I already bought THE MINI SAMPLED by Sonic Freaks. A minimoog model D sampled for EXS format. Very nice. Very analog feel to it. 105 presets and a total download of 2.5GBJust to add to Colin's recommendations, Apple actually list out some EXS 24 library resources here:
