Excerpts from James Morris's message of 2010-07-05 11:39:53 +0200:
a program i'm making (yes that one) will benefit
from knowing about
musical scales. i looked in the source code for non-sequencer (i'll
look at arpage next), and adapted an array there into the following
form:
{ "Major", { 1, 0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 1 }},
{ "Natural Minor", { 1, 0, 1, 1, 0, 1, 0, 1, 1, 0, 1, 0 }},
{ "Harmonic Minor", { 1, 0, 1, 1, 0, 1, 0, 1, 1, 0, 0, 1 }},
{ "Melodic Minor", { 1, 0, 1, 1, 0, 1, 0, 1, 0, 1, 0, 1 }},
{ "Major Pentatonic", { 1, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0, 0 }},
{ "Minor Pentatonic", { 0, 0, 0, 1, 0, 1, 0, 1, 0, 0, 1, 0 }},
{ "Chromatic", { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 }}
(1 means a note is part of that scale, 0 means it is not).
Just one word of warning:
In case you copy code from non-sequencer, make sure to test it. I played
with it today, played with scales, and after I reverted to the initial
"Major" it started to more or less randomly not play notes. Well, I
think there was a pattern to it, but anyway, it seems to be buggy
somewhere around that code.
