[Stk] Callback or qtthread

[Emile Vrijdags]

Hi,

I would like to use stk for an auralization system (schoolproject). Now 
i would like to use blocking rtaudio in a qtthread with its own 
rendering loop, I'm more or less comfortable using qt threading, I have 
very little experience with callback functions. I will have a lot of 
filters on the audio that change in time depending on what happens in 
the main thread, and i don't immediately see how to accommodate that 
cleanly in a callback function.
My question: is there any reason why I should consider the 
callbacksystem better before using my own threadclass? (safety, 
performance, problems i could encounter,..)

Thx
Emile
