Hi Wayne

Thank you for your check.

I thought sin[theta] square brackets used to work, but am not certain.
I think that the square bracket enablement is in Max's nodeeditor code.
Javascript is involved.
I know Windows 11 upgrade modified my MoI 4 default background and alt colors, which seems very strange...
Eventually, in a few weeks, I'll try again on another computer without recent mods.
For now I'll stop worrying about it :-)

I am unsure if sinewave should be a Macro/Node combination, or a brand new Sinewave.js?
