Maybe a new function? Chord Analyser and creator of e new voice

Hi all, i would like to have a chord analyser :-)
it should works like this steps:
- Import a Midifile
- 1. function -> Analysis of the Harmony
- 2. function -> write the chord at right part on the score

maybe with the same function(analysis of harmony) it's possible to create a new voice for example the 3. or the 5. -> it would be a great help for choir scores.

Thank you for your great work.
