Below is my workaround for similar functionality, however, not with the mouse wheel but rather the keyboard arrows.

function [TF] = GTscroll2006b(event,fig)
% GTscroll2006b Use the scroll wheel to navigate figure windows
%
% function GTscroll2006b(event,fig)
%
% Example:
%
% for n=1:length(imgfiles);
% figure(100+n);
% set(gcf,'position',pos1,'windowStyle','docked')
% imagesc(im1(:,:,n),[0 max(max(im1(:,:,workingImage)))]);hold on;
% end
%
% TF=1
%
% while TF == 1
% event = getkey
% TF = GTscroll2006b(event,gcf)
% end
%
% ************** Requires getkey from FileExchange***********************

%% Cycle through figures
CH = get(0,'children');

    H = sort(get(0,'children'));
    if event == 28 || event == 31 % left or down arrow = scroll down
        F = find(H<fig,1,'last');
    elseif event == 29 || event == 30 % up or right arrow = scroll up
        F = find(H>fig,1);
    elseif event == 13
        F=[];
    end
    
    if isempty(F),
        % jump to first or last figure
        if event == 28 || event == 31,
            figure(H(1));
            TF=1;
        elseif event == 29 || event == 30
            figure(H(end));
            TF=1;
        elseif event == 13
            TF=0;
        end;
    else
        % goto next figure
        figure(H(mod(F-1,length(H))+1));
        zoom;pause;
        TF=1;
    end;

end

Very nice idea Gus

I am struggling to find a way to make a scroll wheel modulate the frequency of a sound played by matlab. Would you happen to have an idea on how to proceed.

Amazing function.
I had couple of questions Gus if you don't mind.
I am new to MATLAB (i'm a physician) and this is EXACTLY what I want - almost. I am trying to scroll through a whole stack of MRI images. So in order for this to work, I have to open lets say 25 seperate figure windows and then smoothly scroll through them. However - how can I just open ONE figure window and have ALL my images be scrolling through in it?

I am not much of a code write, but a nudge in the right direction will go a long way (meaning, i can use help function on MATLAB and attempt to write small code under your direction). Thanks!
