I’d be interested to see the patch for that!
I think there’s more that can be done in this space. One of the challenges is cross-plugin inter-module communication of data other than audio/cv. The data interchange over cables that we scaffolded out in this thread Interest in a module+protocol for sending text over VCV cable? - Development - VCV Community (vcvrack.com) is promising. What we built works for any data, not just text, due to the mime type header in the protocol. I think part of what’s needed is two-way handshaking, or some way to set refresh at a given rate. For color animation, we only need a maximum of the screen refresh rate.
