umm… obvious one here, but have you thought of using tri-colored leds, the second color being for each of the midi cores’ midi activity?
and seriously though, do you really need that?
Yep, I thought of those multi-colored leds. But isn’t the problem that in the application only one global midi activity led is implemented? Or can I use J5 of the slave cores? I think not. ???
And I don’t *really* need it, it just seems like a nice bonus. ;D
Otherwise I’ll use the power led for power/midi-activity.
