I have already made a patch that takes single midi notes and change them into coloured squares. Now my teacher asked me to detect chords, too. I know in maxlib there is hte object chord that does this, but my wish would be to have chords and melody at the same time. In a simple, intuitive way: I have a midi keyboard and the right hand plays one note (the melody) while the left one plays 3 or 4 notes (the chords). Is it possible to do something like that? I've tried using "chord", but I don't think it works very well.
