So lets say I run the for loop for two iterations the saved values will be a matrix 1 x 12,774.
n1 = 50; % Number of notes plotted
for i = 1:n1
xx2 = key2note(X,keynum(i),dur(i));
xs = [xx2(i)];
end
spectrogram(xs,'yaxis')

I am assuming that you meant your xx2 has size 1x6387, and you want xs to be of size 1x12774 after two iteration.
n1 = 50; % Number of notes plotted
for i = 1:n1
xx2 = key2note(X,keynum(i),dur(i));
xs = [xs xx2];
end
