Also, I made keyboard map, which I have used in Scala playing in mainly E31for the last couple of months: A# B# Cx Dx Ex A B C# D# E# Fx Gx Ax Bx Bb C D E F# G# A# B# Cb Db Eb F G A B C'# D'# Dbb Ebb Fb Gb Ab Bb C' D' E' It will them work in any such generalized diatonic system.You mean you have a keyboard mapped like this, or you use a virtual keyboard in Scala? Anyway, it'll only work in a system with a single spiral of fifths (singly positive or negative in Wilson's terminology). No good for miracle or magic temperaments.
The link <http://x31eq.com/paradigm.html> you gave says:Miracle scales can be described as subsets of either 31, 41, or 72 note equal temperament. For example, the 21 note "blackjack" scale looks like this:
1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 2 1 /31 1 3 1 3 1 3 1 3 1 3 1 3 1 3 1 3 1 3 1 3 1 /41 2 5 2 5 2 5 2 5 2 5 2 5 2 5 2 5 2 5 2 5 2 /72So the m M-model will work, and also the keyboard layout above, if adding more note names. One must give those names in Scala, but the vectoring is the same.
There is a practical problem: it is nice to have the octaves level. And having a lot m's makes the keyboard span short.
