I have a 16gigs of ram, running 64-bit windows 7.  Im trying to import 50 stereo audio tracks, and everytime a track is loaded, the ram increases inside of sonar. I can see this by looking at the task manager. It rises by the size of the audio track loaded.
 
Im exporting my audio from fruity loops 10.   can sonar be reading these as loops and trying to put them into ram instead of reading off the drive?

If it fits you must acquit. No thats not it. What does it matter if you have the ram flaunt it.  Reading from disk will happen if you don't have the ram to load it into. Clearly you do. You can always give me some if you don't want it. 

Could be that Sonar may try to use as much RAM as it can for performance reasons, depending on how much RAM. This isn't a real problem in most applications. It could be a good thing. However, it should not increase to the point where your system stops working. At some point, Sonar should start writing to disc (file-swapping).  

When you initially import an audio file into SONAR, it only exists in RAM and won't be written to disk until you save the project. It therefore stands to reason that the amount of memory used will be at least equal to the total size of all the files that you've loaded.

I would be just a tiny bit perturbed if the RAM load did NOT increase when importing audio

I should have mentioned that I tried saving, exiting the program completely, and then reopening to see if that would drop the memory count, but sonars memory usage is still the same from when I imported. Could it be because it thinks its acidized loops and its putting into ram? I don't want to treat it as so. I would like the option to be able to choose between adding things to ram or reading from disk because I know have fast enough disk. Thanks in advance

never mind i figured it out, I disabled them as loops, And the ram usage went down
