  4. Multiple answers are possible on diminished (o), augmented (+), m7 <> 6, and m6 <> m7b5, however the computer shows only one chord.
  5. Use the dropdown lists and 'Check' button to verify a chord if needed.
  6. If your browser/OS does not support the Web Audio API, you do not hear the MIDI sound.
