 Without opening pd I think it's something like range $1 $2
and that's what I'm doing when controlling DS from GOP,
it seems the best way to go..

 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.

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
