So, I am not sure if my code is correct comparing from the diagram.
My Code
if true
voice = [1:100,000];
music_notes = {'DO' 'RE' 'MI' 'FA' 'SO' 'LA' 'TI'};
voice(1).pitch(1) = 1;
voice(1).start(1) = 1;
voice(1).duration(1) = 10;
% code
end
just did for voice(1) only.

To create the structure array, do
voice = struct();
instead of
voice = [1:100,000];
The latter code creates a vector, not a structure array.
Then the rest of your code should run fine. I can't remember if there is an advantage (or even a way) to pre-allocate the memory for a structure array. Maybe someone else could comment on that.
