interface.

6. Why are both a note-on command and a note-off command needed in the MIDI
protocol?

7. What is the importance of the "status byte" in the MIDI protocol?

8. Explain why the "sys-ex" commands are so crucial to the further
development of MIDI instruments, software and hardward.

9. MIDI has three different kinds of "ports".  Explain what each does.

10. What is the maximum recommended length of a MIDI cable?  What would you
do if you needed to exceed this length?

11. Explain the difference between a MIDI chain and a MIDI loop (star network).
