i never used the 64 version of Cubase. However, recently I bought some VSL libraries that require a lot of RAM, so I’ve installed the new Cubase 6 in 64 version.
Wow, it’s almost unusable with 32 bit plugins. Halion 3.1 doesn’t work (fortunately there is a 64 bit version I’ve just installed now), and the plugins that don’t make VST Bridge crash use A LOT more CPU.
Sincerely, I expected better 32 to 64 bit performance from the creators of the VST technology
So, no 64 bit for me yet… I have lots of expensive 32 bit plugins I can’t just throw away…
Windows doesn’t seem to have such problems running 32 bit apps in a 64 bit OS.
