1 = Frame count MS nibble
2 = Seconds count LS nibble
3 = Seconds count MS nibble
4 = Minutes count LS nibble
5 = Minutes count MS nibble
6 = Hours count LS nibble
7 = Hours count MS nibble

This is the ID number (manufacturer ID) that specifies the
manufacturer whose exclusive message this is. Roland’s

fined in an expansion of the MIDI standard as Universal
Non-real-time messages (7EH) and Universal Realtime
Messages (7FH).
