please : info about Tracktion hd streaming "engine"

[geoslake]

Im not a tracktion user yet, but i tried the demo.
I usually use FLstudio, but now i have a problem, as i want to stream some big waves from HD in a project.

Problem is that in FLS, streamed audio data stays in ram after it has been streamed, so i end up with a huge 600mb "fl.exe" in the task manager, which is a problem, as i "only" have 512mb ram.

Tracktion doesnt have this problem, it just fills a few mb (probably for hd cache) but it doesnt really increase.

FLS's author told me he uses the standard windows mapper for this. I would like to know, if possible, if Tracktion uses something else, or has something special in its code to free up the ram.

Many thanks.
