Is there any follow up to the original manual that I’ve missed? Or, where can I go to get more info on using the deeper end of the mod matrix functions - Random, Rand, Var, etc…I can’t seem to find any detailed information on these parameters.

There is no detailed info on these except the list in the firmware upgrade text that introduced them. That was just the barest of bones abstract description.
I’d pay money for a written and video textbook explaining in depth with real world examples of what these Var and function features can do.

Also, following up on my own question, more information on this is also available in the Firmware update manual 1.3.0 which you can download from the moog website.
