I'd like one day to understand how to implement DS into a GOP, it's a
bit triky, then on a single window it's possible to have the whole interface.
I wrote something about it in a thread some weeks ago:
http://lists.puredata.info/pipermail/pd-list/2013-05/102819.html
it's not really possible to do this in the context we're talking about
because we don't know which scalar is modified when it's embedded into
an array, a way would be about using y value, but in this case y is
always = 0
ah, you mean an "element" instead of a scalar (although they're all
scalars when drawn). the only way I would remember now would be use the
[struct] output to trigger a comparation of the previous array with the
current one, saved as lists. not optimal at all, but it can work if there
aren't too many elements.
