white noise, some distortion, bandpass filters? Seems pretty straightforward, have you tried something already or read up on the physics behind it?
cheers

Hi,

Yes, I was trying white noise with biquad~ bandpass filtering but that did sound (very) different :-(
It seems more difficult that I thought thats why I was posting.
No idea where to read about the physics..

I had this happen unexpectedly while experimenting with modal synthesis and rapid pitch fluctuations, so you might want to look there.

there is a book by andy farnell, which covers a lot of these topics in minute detail and gives examples in pure data (easy to translate to max):
