I just upgraded from X2 to Platinum. I'm loading a file that uses ~90% of my 32gb (lots and lots of Kontakt VI's). In X2, it played with no issues - maybe a very occasional dropout, which would get fixed the next time through. In Platinum, a) there are frequent dropouts, and they increase with repeated playings; b) there is constant disk activity at or near 100% (in X2 it stayed near 0%); c) RAM usage increases with repeated playings until the program crashes. 
 
Does anyone else see this? Is there a setting in Platinum that needs to be changed?
 
Thanks for any help,
Bill
 

Bill Clark -
I can't say that I have seen it exactly like your describing it - but - it sounds like you might need to increase your buffer size.  This is just a thought not knowing if you have already considered your buffer.
 

I've tried adjusting the driver setting for mixing latency buffer size; I had it at 20 msec (882 samples), and bumped it up to 100 msec; no improvement. In Kontakt, I tried upping one instrument's preload buffer size from 30kb to 60; this causes things to go downhill fast as SONAR grabs more and more memory. As I said, all this was working fine in X2, so it seems that something has radically changed about the DFD algorithm. I'm hoping there's some new setting will get it back to a point where I can use it; otherwise it'll be X2 for a while yet for me.
 

It sounds like a memory leak i.e. unused memory is not being returned to the pool. 

I also changed the options under Sync and Caching - I had read and write caching enabled, so I disabled them, and I upped the playback buffer size from 256k to 1024k. It's very slightly better, but the same behaviors still happen: frequent dropouts, increasing memory use over time, and constant disk activity.
 
I'm baffled at this point....

Agreed -- but if it's a memory leak, I'd think everyone would be seeing it. Maybe the only reason I'm affected by it is that I'm using so much of my available RAM?
 

Probably a pointless question, but are you using the latest versions of Sonar and Kontakt? What about Windows Updates?

Yes - I just downloaded Sonar yesterday, and updated Kontakt a few days ago. Windows (7) is up to date as well.
 
I just loaded the project again in X2 and paid closer attention to how it behaves. I see some of the same things; memory usage goes up until all samples are loaded, then it levels off and stays steady. There are dropouts (more than I remembered), but they do all go away the second time through. It could be that Platinum is just taking more memory than X2, so it's putting me a lot closer to using 100% of RAM - maybe it's not able to do the buffering it wants to do, or something like that. I've got more memory coming (it'll be up to 64gb!). We'll see what happens then.

Sounds like it.  Doubt that the majority of users frequently run at 90% of installed memory.

Hi. Have you tried yo increase the "Prepare using ...ms" in Preferences, MIDI, Playback and Recording to 500? It changed in Platinum, IIRC.
All the best.
