[With sound] This shows the comparisons between regular TET/EDO (Equal Temperament), and the Just Intonation ratios of the following, shown from left to right; 1:1 (0 Dimensional, Itself) 5:4 (3 Dimensional, Major Third) 3:2 (2 Dimensional, Perfect Fifth) 7:4 (4 Dimensional, Septimal Minor Seventh) 2:1 (1 Dimensional, Octave) This shows the comparison of the ratio approximations with; 12EDO (Modern and Western tuning) 41EDO (Efficient Approximation, according to LΛMPLIGHT) Custom EDO (31 by default) - You can change the EDO by pressing [K]. This as well shows how many steps (rounded to a 2 decimal amount) of the 41EDO and Custom EDO. For custom ratio comparisons, press [Q]. It will ask you for the Numerator first, then the Denominator. This uses Microtones, notes away from the usual standard 12-EDO tuning.
