Hi Pilou
>> I load waves.3dm
load waves.nod launch it
move the different Knobs --> nothing arrives!
What I miss ? What is the process ? Some selections ? ... <<

in the Weaves 3dm file there are several objects that have been
instanced in Moi Elephante with Get by Name ,
ascertain with Update that the instanted objects appear on the screen
and then Run ...
do not move any Knob ... before you understand how it was built
the set, some parameters make sense only when compared to objects
instanced input ...

I'm sorry Pilou, but I can not post images and files directly
in the Forum; I have to use (thanks to your suggestion) Mediafire to be able to share my works with you

have a nice day
alberto

PS-I tried with my laptop, everything goes perfectly
