Berlin WW - RAM Hog

I don't own BWWs, so I'm not sure how much memory it takes up (although I hear it's quite a lot). But if you purged all samples, I think the problem is that the Kontakt scripting takes up memory for each instrument, and it does not matter if you do it with one instance for all or an instrument per instance. The more complex the scripting, the more memory it takes. And the scripting can't be purged from memory.

I'm not a Cubase user (I use Reaper) but what I do is disable the tracks completely, with all of the FX offline (I purge the samples, too). The instruments are available, routed and set up, but not taking up any memory. I have a custom action (a custom set of commands done one after the other, like a macro) that disables or enables the track completely. When I enable a track, Kontakt comes online and everything is as normal. This allows me to have a large template (although compared to some other folks I don't yet because I don't own too many libraries). But in theory, I could have as many tracks as I want with little to no impact on RAM, other than the hit it takes from Reaper creating a track, which is like 15Mbs or something like that.

My situation is a little different, though, so I'm sure someone here that uses both BWWs and Cubase can provide a better solution. But I'd look into the possibility of disabling tracks, if that's available for Cubase. It is the only thing that allowed me to have a template without kicking my computer in the balls everytime I open my DAW.

 

One instance of Kontakt uses ~60 MB of RAM. If you can squeeze it all inside one Kontakt (I have it like that), you can save 550 MB.

But it definitely shouldn't be using that much. Mine use 5GB when everything is loaded up (non-purged) with the Mixed mic. What is your preload buffer size in Kontakt? Head to settings (the gear icon) the Memory and read out the buffer size. Lower value will use less RAM but will utilize the CPU/disk streaming more and vice-versa.

OT samples don't really purge that well in my experience (they also use a lot of persistent variables in their scripts (source: ED) and that's why the project size bloats up whenever a lot of OT instruments are used).

 

No, you just purge it. Resetting markers will delete all the markers, so if you were to play your piece after the fact, it would "mark" all the samples used, and if you then hit "Update sample pool" it would purge all except the marked ones.

"Purge all" always does what it says: it purges all.

 

Another thing that might help, to an extent, is to lower the polyphony for each instrument in Kontakt -- voices use RAM and CPU cycles. Usually these libraries come with an excessive number in there.

But when lowering the polyphony, play a fast phrase to test whether it still sounds all right.
