Currently, I need to find something to bring in a bit of cash! Registrations of HARMONY have been rather rare (in fact I have given more 'free' registrations to testers than I have had paid ones) and I would like to find something more lucrative.

I already have a number of programs which analyse MIDI files (Hands-on Midi Chords, for one, which analyses and reports on the chords being played in a file), so there is something to build on.

Any suggestions for the requirements (Yes, MIDI in, Score out, but that's a trifle ambitious for a first attempt!)

Example: output format? MIDI in - MusicXML out would probably be best, as there are plenty of top-class scoring programs which now import that format.
