The Buchla LPG  (I have Peter G's spaghetti-board
copy) is essentially a non-resonant LPF.  The one
I have actually does have low resonance, intentional,
authentic... or not I don't know.

Even the MS-20 is well behaved at low resonance and
looks like most other 2 pole LPF.  Youc can't really
compare them unless you 'mutate' the Buchla
design... which I can see ~has~ been done. :^P

I need to study that one a little more...
