Do major scale in three system. Firstly one by one, then pythagoras + just intonation (5 limit), pythagoras + 12tet, just intonation + 12tet, and at the end pythagoras + just intonation + 12tet alltogether. Reference notes are la4 and their frequencies are 440hz each. Sinus waveform. Prepared using csound.
16-tet scale on C (75 cent steps). Easley Blackwood, Jr.'s notation for 16 equal temperament. Intervals are notated similarly to those they approximate and there are fewer enharmonic equivalents. MIDI pitch bend appears to match intervals (0,56, etc.).
21-tet scale on C (57.14 cent steps). Easley Blackwood, Jr.'s notation for 21 equal temperament. Intervals are notated similarly to those they approximate and there are distinct enharmonic equivalents (E-sharp-down = F-down). MIDI pitch bend matches intervals.
24-tet scale on C (50 cent steps). Easley Blackwood, Jr.'s notation for 24 equal temperament. As only "ups" are used, there are no three-quarter flats and quarter flats are enharmonically spelled (Dd = C#↑). Pitches are split into two groups of 12. MIDI pitch bend is correct for intervals.
7-tone equal tempered scale represented in traditional notation. + and - indicates approximate distance above and below notated pitch. Pitch bend matches intervals.

*256 tone = 1 step in 768-tet on C. Equal-tempered: 21/(6*128):1 = 1.56 cents cents. MIDI pitch bend: 64,32 on m2 The 1023rd subharmonic is 1.69 cents, and Sibelius's pitch bend commands are not fine enough to distinguish between these two intervals, as is human perception.
