Gotcha. I removed the [change] objects from the [pd debytemask]
subpatch. And I also agree, that it would be ugly, if digital pins fire
without changing their state.

Actually, I found the table based approach not that complicated and I
think it is more scalable (it covers all possible 16 groups). I added a
[pd polychange] subpatch that does exactly what you describe. I
hopefully tested it more thoroughly this time. See attached patch.
