Sorry,

I had a look in the manual of the fcb1010, and according to the midi implementation chart the fcb1010 does not transmit 'system real time messages' and 'system common messages'

In MIDI system real time messages are things like start continue and stop.

system common messages are probably used to select fills and sections (I don't have any Technics gear, but it it's the sensible choice)

Sorry to disappoint
