; This tester plays 24-tone octave. If you do not know how many steps one
; semitone has you can test it experimentally by this example. When you
; hear the scale progressing smoothly then the resolution is acceptable.
; Hint: 24-tone scale sounds like a 12-tone chromatic scale, except it
; has extra step in between each note.
