Changing the intervals between courses

Here is the Belcanto used to tune The Eigenharp like a guitar, but starting from A on the first course

error 11 1131
Error 1 listen

1471 12 1436 23 15 1241 67
course 2 offset to 5 interval set

1471 13 1436 23 15 1241 67
course 3 offset to 5 interval set

1471 14 1436 23 14 1241 67
course 4 offset to 4 interval set

1471 15 1436 23 15 1241 67
course 5 offset to 5 interval set

To change interval using scale steps instead of chromatically type;

error 183 11 1131
Error group 1 listen

1471 12 1436 23 17 4177 67
course 2 offset to 7 semitone set

1471 13 1436 23 17 4177 67
course 3 offset to 7 semitone set

1471 14 1436 23 17 4177 67
course 4 offset to 7 semitone set

1471 15 1436 23 17 4177 67
course 5 offset to 7 semitone set

To put it in a major scale:

135 23 4153 67
scale to major set

To change to melodic minor:

135 23 4213 4155 67
scale to melodic minor set

To change the order of the keys and reverse the keyboard order on K group 1 type the following:

error 65 11 122
Error as 1 choose

The keys will then light green and orange

Press the keys in the order you want them added

Press the last key twice and this will exit edit mode

To do the same for course 2 type:

error 65 12 122
Error as 2 choose

Then repeat previous instructions

To make a chromatic keygroup with no notes repeated type:

error 65 11 122
Error as 1 choose

Then push every key in the keygroup

To make a horizontal layout say;

error 183 11 1131
Error group 1 listen

error 122
Error choose

Then select the keys horizontally.

This enables six chromatic octaves on the Tau and 10 on the Alpha

To mirror the courses say:

error 183 11 1131
Error group 1 listen

error 65 11 122
Error as 1 choose

error 65 12 122
Error as 2 choose

error 65 13 122
Error as 3 choose

error 65 14 122
Error as 4 choose

error 65 15 122
Error as 5 choose

To remap the keys on the pico say:

error 12 5
Error 2 hey

error 122
Error choose

Again the lights will appear and choose the notes in the order you want them

Pressing the last one twice will exit edit mode
