or maybe a 2nd order, since it can resonate. sorry, I'm not good at filters.

No worries, by the way, I really liked that [tong~] abstraction that used [cpole~] to create a damped harmonic oscillation, I'm using that for "spring like" signals and writing an external for it. Also by the way, [vcf~] is based on [cpole~] so it is quite similar, but [vcf~] has a gain compensation so the maximum gain is at 0dB.

I know a little bit about filters and will try to investigate more. I've been avoiding physical modelling for ages and it seems its finally time to dig in :)
