Sound with filters

I have created a guitar simulator with digital sound synthesis. I have the output of 6 filters as strings of a guitar and I want to play them together just as in the filterguitar.

The filter I have used as shown below.

%creation of the filter
for u=1:umax
B= [0 b1d(u)];
A = [1 c1d(u) c0d(u)];
g=g+(fe1_mu(u)*filter(B,A,x));
end

I have 6 Gs like that and I want play them together.

Can anyone help, please??

mean() the six signals and output that.

This might create unwanted results under very specific circumstances. E.g. if both filters create the same wave form, but the a phase shift of Pi, the resulting sound is silence. But this is the physically correct solution and not a computational problem.

Thanks for the answers. But the sound produced are not like the filterguitardemo in matlab.
