Hey hey,
I think I remember that there is a way by FM or PM to simulate bandpassed 
white noise, by either modulating white noise with a sine or the other way 
around with either FM or PM, but I can't find anything readible supporting 
that vague memory.

Does anyone here have a basic recipe?

Alternatively, here is what I'd like to achieve, perhaps there's a completely 
different route: through additive synthesis (of sines) I want to build up a 
sound and then introduce a slightly noisy compoenent, in relation to the 
harmonics/partials in that sound. A bit like ZynAddSubFx's/Yoshimi's SubSynth 
does. Using classical bandpass filters is unwieldly, since the bandwidth may 
greatly change the volume.

Best wishes and thanks,

Jeanette
