There is a Boss ME30 patch page on the web but, irritatingly, there are no “previous” and next” buttons:

I’ve tried the obvious things like changing n-s to t-z in the URL and this did indeed get me the t to z patches. g-m gets you those patches but a-f doesn’t work for some reason. Still, quite a lot to look at.
