The aging MIDI Standard did not define any Chord Data.

Various different programs have, over the years, incorporated their own proprietary methods of handling that situation -- or not.

Each program that does attempt to do chords does it differently.

All in all, pgmusic's MIDI Chord Wizard is actuall still one of he best MIDI chord interpretors I've used. The mistakes will likely always come about due to whatever notes are in your target Midi file, as already mentioned. Passing notes, grace notes, etc. often end up as one of the notes used in the chord interpretation. Unless and until our PCs are able to incorporate quite a lot of Artificial Intelligence into the mix, it will be up to the human intervention to clean up those mis-identified chords.

Still, the MIDI Chord Wizard proves to be a great time-saver. If nothing else, you get the song's chord grid all laid out on the right bars instantly. Correcting chords within that grid layout is a lot faster than starting from "scratch".
