Extended chords not mapped correctly?

See original GitHub issue
  • Does mir_eval handle extended chords correctly? It seems to ignore everything beyond the seventh:
In [5]: mir_eval.chord.encode('A:maj(9)')
Out[5]: (9, array([1, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0]), 0)

In [6]: mir_eval.chord.encode('A:maj(9)', reduce_extended_chords=True)
Out[6]: (9, array([1, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0]), 0)

compared to

In [8]: mir_eval.chord.encode('A:maj(2)')
Out[8]: (9, array([1, 0, 1, 0, 1, 0, 0, 1, 0, 0, 0, 0]), 0)
  • Does it make sense to treat chords such as A:maj(9) and A:maj(2) differently in the first place? Both comprise the same pitch classes, and I doubt that one can distinguish between the two in the sound mixture of e.g. a pop/rock song.
