[PD] pitch track

[Chris McCormick]

Hello,
Firstly, thanks for all the help from this list so far - it's been invaluable.
I have another question. When I was perusing the help patches I remember 
noticing some kind of a pitch tracking object, or maybe it was an entire 
patch. But for the life of me I can't re-locate it. What's the best way of 
doing pitch detection in Pd?

Chris.
