We need someone to modify the source code of Midi.net open source library which can be found at http://code.google.com/p/midi-dot-net/
The library has a chord class that can detect chord from an array, it can detect most chords however some cannot be detect.
Your job is to modify the code to add all the missing chords that it fails to detect. Please check attachment for all the chords required, note that only some are not detected and you only need to add those to the detection pattern.
