I must be the bug!

I got my E1 MK11 a few weeks ago, I have read the manual a few times and I can’t find how to prevent unwanted data going to the wrong interface. I just don’t understand the concept or the utility of hardwired parallel port.

For instance, if I have a unit at the end of the OUT1 DIN1 port that receive a mass of CC data upon a snapshot recall, I obviously don’t want to clog the USB1 port with irrelevant data that will reach a unit that don’t need them, or worst, that will respond to them in the wrong way!

Also, is there a way to rechannelize a preset globally?

My guess is that LUA could do all that but I can’t find my way around…

Thanks for any clue about that!
