Song Position Pointer, Song Select, Timing Clock, Start, Stop, Con-
tinue, System Reset are all for controlling sequencers and rhythm ma-
chines. See the MIDI Implementation Chart for your device.
If there are no MIDI messages that have to be sent, one of these is sent
every 300 msec just to let the receiving devices know that there is still
someone out there. If there have not been any MIDI messages for a
long time (like
1/2 a second), the receiving device assumes that some
error has taken place (eg. a MIDI cable was pulled out by mistake) and
will stop all notes.
These are unused, and reserved for future expansion.
