What type of signal did you run to it? You could try a compressor in
front of it; I think that helped. I can't remember if filtering
helped. Maybe a bandpass tuned to your expected input, or a
combination of high- and lowpass?
There are a
few these days, but the only one I have ever used is
aubionotes, from the aubio package.

Thanks. I didn't know about aubio, though apparently it has been
around for ages.
Setting up aubionotes is very easy. Unfortunately, it doesn't work
quite well enough for me (pitch detection is error-prone). But it is
probably possible to fine-tune the detection parameters by going to
libaubio directly (aubionotes doesn't have too many options to tweak,
and the ones available aren't documented).
How did you use aubionotes? Any special tips?
