Hi, you might be interested in C::NTR::L http://cntrl.sourceforge.net.
It's
a Pd-based application which recognizes pitch out of an electric bass
guitar, guitar, or piano (only two octaves) and trigger audiovisual fx (outputting
a bang everytime a new note is recognized using a proper threshold system to avoid weird behaviour).
You can also set manually the frequencies you want to track.
I use it often in my performances.
If you need help while using/de-constructing it, just drop me a line, I'll be glad to help you.

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!!!
