Since no version of Music Creator is officially supported for 64-bit operating systems, and all the plug-ins likewise, it's going to be a crap shoot whether anything will work. It might, it might not.
Since we're all traveling into the future, including computer manufaturers and software developers, 'a little while' will still be too late.

Even MC 5 isn't 64-bit compatible, but many folks use it on their new computers with few problems by running in 32-bit compatibility mode. And it comes with native VST support, so you won't need an adapter.
