[PD] triggering fx

[Jon]

i'm planning a patch that will listen to live acoustic instruments
(via fiddle~or sigmund~) and then trigger some effects when the
analysis objects detect certain frequencies. the catch is that i not
only want to trigger these fx: ideally the effect should be sustained
until fiddle or sigmund detect some other frequency. below is a small
piece of code that works for this (triggers at 400, stops at 500), but
i'd love to see other approaches, especially if they are less
cumbersome (because i don't wanna do this with a pair of frequencies,
but a bunch of them!)
thank you!!!
