Examples of the networks output:

Example 1:

Last note: D5

Pitch network output (including sharp or flat note units):

 C C# D D# E F F# G G# A A# B 0.0742 0.0082 0.3730 0.0331 0.1546 0.1688 0.0008 0.1365 0.0301 -0.0062 0.0121 0.0441

Interval network output:

 -12 to -6 -5 to -3 -2 to -1 0 +1 to +2 +3 to +5 +6 to +12 0.0405 0.1718 0.1893 0.3024 0.0169 0.1341 0.0719

Pitch network output, after eliminating low values (lower than 0.25 * max value = 0.25 * 0.3730 = 0.093):

 C C# D D# E F F# G G# A A# B 0 0 0.3730 0 0.1546 0.1688 0 0.1365 0 0 0 0

Interval network output, after eliminating low values (lower than 0.25 * max value = 0.25 * 0.3024 = 0.151):

 -12 to -6 -5 to -3 -2 to -1 0 +1 to +2 +3 to +5 +6 to +12 0 0.1718 0.1893 0.3024 0 0.1341 0

Possibilities for next note:

 Note Probability D5 73.37% F5 14.71% G5 11.91%

Example 2:

In some cases, I wanted to consider only key notes, and not sharp or flat notes. In this case – I ignored the output of the sharp or flat note units, and considered it as 0. Sometimes I also gave 7 as the maximum value for the next interval.

Last note: E6

Pitch network output (ignoring sharp or flat note units):

 C D E F G A B 0.1088 0.0763 0.1923 0.2324 0.3367 0.1077 -0.1396

Interval network output:

 -12 to -6 -5 to -3 -2 to -1 0 +1 to +2 +3 to +5 +6 to +12 -0.0050 0.1365 0.1077 0.2723 0.1040 0.2364 -0.0065

Pitch network output, after eliminating low values (lower than 0.25 * max value = 0.25 * 0.3367 = 0.084):

 C D E F G A B 0.1088 0 0.1923 0.2324 0.3367 0.1077 0

Interval network output, after eliminating low values (lower than 0.25 * max value = 0.25 * 0.2723 = 0.068):

 -12 to -6 -5 to -3 -2 to -1 0 +1 to +2 +3 to +5 +6 to +12 0 0.1365 0.1077 0.2723 0.1040 0.2364 0

Possibilities for next note:

 Note Probability E6 39.27% C6 31.42% G6 15.71% F6 12.52% A6 1.06%
