CMC-PD and Midi Output in Cubase7.5

I’m new at the CMC-PD and have a question. In Cubase 7.5, haven’t use it with any other version, I’ve notice in the transport the midi output LED jumps repeatedly. Is this normal, because this don’t happen when it’s not connected. I need your Help ?

It is a long standing complaint for all CMC. They have an annoying implementation of part of the MIDI spec. It is “working as designed”. Either ignore it or throw the CMC in the trash.

lol… Thank you for your reply, appreciated.
