Bob, what Neil is saying is that it is the VSTis that he is using that is eating up his ram, NOT BiaB itself. I know as I had the same problem. For instance I would run out of memory if I had a 32 bar song with the 5 midi parts going into Kontakt and I loaded Kontakt with 5 ram intensive patches. I would also run out of memory if I tried the exact same thing in Sonar.

I did work out a PITA work around in Sonar but I decided then and there to go 64 bit only. I have 16 gigs of ram now and no problems in Sonar. I don’t know if the 32 bit BiaB will access all 16 gigs when running in 64-bit mode. That is something I should find out, someday!

If one is using RTs only and/or a GM synth they will not run into this problem.

PS-an after thought. I think that those of us who are heavy softsynth midi users are in the minority here in BiaB land.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
