Thanks Claude and Iohannes.
seems this is likely an issue with the recycled signals then...
i tried the method Claude suggested, and even with any tweak i could think of, it's still not working.
Iohannes, what do you mean when you say:
"which signals get re-used is a function of the surrounding patch, and unrelated to the creation order within the object's dsp-function."
???
Is there some sort of logic or rule to this?
