))) More of the program could run in memory etcetera

The program already runs 100% in memory, that wouldn't change in 64 bit.

What is the "etcetera" reason you are referring to. The only reason I know of is to support 64 bit plugins, and BB 2015 now does that with jbridge.

Of course you don't need to tell us a reason, but people like me looking for reasons to make BIaB 64 bit someday, would like to see a reason more than "etcetera" . Many people don't understand what a 64 bit OS is, and when they see etcetera listed as a reason, they think that there are lots of important reasons.

BiaB 2015
- runs on 32 bit and 64 bit OS. If it was 64 bit, this would be 64 bit only.
- supports both 32 bit and 64 bit plugins
-64 bit programs have to use 64 bit implementations of hosts, plugins, drivers etc., and these are rather new, and typically not as stable and mature as the 32 bit ones. This same point is made by Ableton on their discussion of the issue. https://www.ableton.com/en/articles/64bit-myths-facts/

Have Fun!
