When I log into Korg ID, then go to Registered Products, then I see the Korg Collection installers. At the bottom is a link to Bonus Program. Inside there I see 21 Expansion Packs.
Simon - I'm still having difficulty with Legacy Cell. I only have one installer for it, not a choice of a 64-bit or a 32-bit. I installed it fresh, then put all of its dlls in a folder and ran Jbridge on the folder. Only the MDE-X file resulted in a bridged 64 bit file. Regardless of whether I scanned that from a bridged folder in my VST directory, or by moving the bridged 64 bit dll to the same folder as the rest of the Korg Collection dlls, the Legacy Cell still doesn't come up in the DAW. It works fine as stand-alone. How did you make this work again, maybe with a bit more detail?
