[PD] triggering fx

[Marco Donnarumma]

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.
