Need help for addition of cells

Here is portion ofmy code
alto = cell(1, length(keysa));
for i = 1:length(keysa) % The for loop continues till number of Keys
alto{i} = note(keysa(i), dura(i)); function is called
end
treb = cell(1, length(keyst));
for i = 1:length(keyst)
treb{i} = note(keyst(i), durt(i)); % function is called
end
Now what i want is that to make a final cell array in which treb{i} and alto{i} are added and stored one by one i mean
final{1}= treb{1}+alto{1}
final {2}= treb{2} +alto{2}
so final is addition of both two.
I tried this one but gave error
final=cell(1,length(keyst)
for k=1:length(keyst)
final{i}=alto(i)+treb(i);
end

final=cell(1,length(keyst))
for k=1:length(keyst)
final{i}=alto{i}+treb{i};
end
Or
final = cellfun(@plus, alta, treb, 'Uniform', 0);

length of treb and alto might be the same, but each of them is a cell array possibly containing a vector or matrix. Do the sizes of those agree?
Try this:
find(cellfun(@(A,T) ~(isequal(size(A),size(T)) || numel(A) == 1 || numel(T) == 1), alto, treb))
If any numbers are printed out, then they are each indices K such that alto{K} cannot be added to treb{K} because the sizes are different.

I am doing multiple things at the same time; I can't always notice and test and write a response within 8 minutes. :(

Shrug. You never did indicate what you want the additions to mean, so I just followed your outline, which is not going to produce a single array suitable for using in soundsc()
If you are attempting to do additive synthesis of sound, then you need to define the time relationships between the various components.
If it happens that the alto and treb of each pair are to be played at the same time, but only one pair at a given time, and no pause between adjacent pairs, then you want
fullsound = horzcat(final{:});
and then soundsc(fullsound,fs);
If you get a dimension error when you try that, change the horzcat() to vertcat().
