Looking at this page, I don’t know what ME number to use for the main ME for Carbonite Ultra to control it with a RossTalk Command?

If I want to auto trans KEY 1 on the MAIN ME (P/P), what command should work?
Is it ME:PP? or ME:1?
Awesome! thanks so much, the specific application I was trying to use hated the ME:P/P and would crash every time, so good to know that ME:0 works…
Seems like I also got ME:PP working (no slash)?
yes it looks like ME:0 , ME:P/P and ME:PP will all direct to the Program Preset ME of the Ultra…
Looks like they made sure to cover all the bases for you
