You might also be interested in existing free-software projects
which have implementations of pitch-tracking. For example aubio
(which is also wrapped as a vamp plugin), and clam:

http://clam.iua.upf.edu

In clam we have a user interface program called Voice2MIDI

And now one of the Google SoC projects is heading towards
improving it and porting it to real-time among other things.
You can also have a look at clam's pitch shift and pitch
discretization transformations. Feel free to ask questions in
the clam lists.

Best,
Pau
