MIT has some externals called pitch~ abd fiddle~. 

I am new to doing realtime pitch detection. I was wondering

if someone could give me some tips on using these. Of pitch~ or 

fiddle~, which is better? If I had a prerecorded snipet of the

instrument I was going to interact with, is there a way I can do 

some spectral analysis to help train pitch~ or fiddle~?

Of course. Use whichever works best for you. Some people may have had 

more success with fiddle~, some people will prefer pitch~, some 

people will say both work equally well (or poorly).

It's not so much a question of "training" either (in the sense of 

training neural networks), but of tweaking parameters to best suit

This sentance from Tristan's website is a tipoff:

"Pitch tracker based on fiddle~ from Miller Puckette," that they're pretty similar.

These objects aren't trainable. But you can increase the quality of your analysis by filtering out extraneous noise. I put some serious high pass filters before either object, and sometimes lowpass, too. I try to keep my microphone placement super close (to avoid any reverb) and consistent.

It take some fiddling to get these to behave. Some things (flutes, violins) are easier than others.

Has anyone tried the "WIDI Audio To MIDI" VST plug-in Max/MSP versus

TIA for any feedback.

Worth keeping in mind too that you will tweak fiddle~ in a specific

room/studio/hall or whatever. When you go to a different place with

different acoustics it will be necessary to tweak again--probably not

as much work as getting fiddle~ to respond reliably to a particular

sound in the first place, but things do sound different in different

places, both to you and to fiddle~. Not to mention the potential

effect of using different microphones, etc.

pitch~ or fiddle~, that is the question...
