hi list, I'm using a 2nd order lowpass resonant filter whose coefficients I'm getting from the famous Eq-cookbook and using it inside a feedback loop to implement karplus-strong.
I also have a coded object for that (pluck~) and the 'q' parameter is 0.5, which is a "safe" setting, i.e. the filter doesn't get unstable and blows up.
I was now trying to find a higher 'q' coefficient but it's hard to know where I can go "exactly" just under it could blow up.
Is there an easy way to know this other than trial and error?
thanks
