Every button I've put a macro on has been initially active on every device. I did discover that AFTER the macro is created you can remap that key in one or more devices and the macro will still be active on the rest, but not on the ones you remapped. Following that theory, I'd suppose any device you programmed AFTER having macros on one or more standard keys (not macro keys) would overwrite the macro command on the keys it wanted to use by default.

I'm not an expert. I have just experimented on my Cinema quite a but trying to find my own answers to the questions everyone seems to be asking and sharing them here. If you discover something contrary to what I've posted here please post it. The more info we have, the better our total understanding will be.
