Know of anyone who makes and can license such stuff ?.
Couldn't you just build your own? If you know the application will be
receiving a fixed buffer with a single note, the FFT should be pretty
easy. Create a lookup table to map the result to a MIDI value. You
only have 128 possible values, so the lookup will be quick. I remember
seeing Apple example code with FFT (maybe in the QuickTime meters
example?) You can also build them quickly in CSound (http://csound.sourceforge.net/
) or MatLab if you want to play around with it conceptually.
