Messages to Max in a standalone?

Hans Leeuw's icon

Hi,

I want to use messages for Max in a standalone to be able to let my users (psychoacoustics course participants) change the color scheme, this also as part of a neuro-divergent inclusion investigation. The standard <; Max colortheme $1> does not work. I also tried replacing Max with the name of my standalone, whose name I chose the same as the name of the patch. That does not work either.

Any other way to do this?

Best, Hans.
