On the technical side, even though 64-bit operating systems can run 32-bit applications, behind the scenes very memory address reference has to be translated from a 64-bit memory location to a 32-bit memory location. In a 64-bit app, that memory is addressed directly. On today's i7 processors, it is probably negligible, but in theory, that translation takes some time. And if a 32-bit programmer did some non-standard tricks to address memory (for performance, for example), it's possible that the 32-bit app will not operate properly at times in a 64-bit environment.

So, if the application is properly coded, you should see a better performing application running 64-bit code on a 64-bit operating system.

And as has been stated, because it's 64-bit, you are no longer constrained by a 4GB memory barrier of a 32-bit system. Even if your computer has 32GB in it, a 32-bit application can only use 4GB of the 32GB. Now the 32GB gives you more memory space to run multiple 32-bit applications, each application is constrained to the 4GB memory space. While theoretically, you could address 16 Exabytes in a 64-bit environment, today Windows 10 64-bit lets you actually address 128GB of memory (32 times what Windows XP supported).

So, if you use large sample libraries (which you probably aren't really doing much in BIAB), you could natively load all into memory. JBridge gets around that by fooling a 32-bit OS into thinking it's 64-bit, but there are overhead and constraints with that (and id doesn't always work).

And the world is going 64-bit, so as has been said, this will definitely set PGMusic up for the future (at least until a 128GB OS arrives).

Now, if we can just get RealBand and PowerTracks to 64-bit, and get all the plugins and "called" mini-apps up to 64-bit, then that will be "da bomb".
