Hey Maxime, thanks for the quick answer. Actually I thought, I had tried SetValue() with that ID. But either I did something wrong or I tried something else... anyway, thanks. Just checked: Yes, I did something wrong. I stupidly just passed a string instead of a maxon.String. With the latter it works, not that I doubted your proposal. Maybe would be good, if SetValue() could throw an error, if a wrong type gets passed instead of just doing nothing. Also thanks for the pointer to Dunhou's project, I was already aware. Nice project! And indeed I peeked into it regarding some Arnold peculiarities... Cheers, Andreas

Bummer. But thanks, Maxime, for the quick reply.
