Ptr" messages will be transmitted.
Pressing STOP during playback, fast-forward or rewind will transmit the "Stop" command.
Pressing STOP while playback is stopped will transmit "Song Position Ptr 0". If STOP is pressed
when the current song position is "0", no command will be transmitted.

Pressing << or >> will transmit the MMC command for the function, and will begin transmitting
"Song Position Ptr" messages. The "Song Position Ptr" messages that are transmitted depend on
the current song position. "Song Position Ptr" messages will begin with the current song position,
and proceed forward indefinitely, or backward until song position "0". If << is pressed when the
current song position is "0", no "Song Position Ptr" messages will be transmitted, and only the
MMC command will be generated.
Pressing STOP, or REC will transmit standard MIDI Machine Control (MMC) commands for each
function.
Pressing PLAY will transmit the MMC command for the function, as well as the MIDI "Play"
command, and will begin transmitting MIDI Beat clock (Timing Clock). If PLAY is pressed when
the song position is "0", "Song Position Ptr 0" will be transmitted before the "Play" command. If
PLAY is pressed when the song position is not "0", the "Continue" command will be transmitted
instead of the "Play" command.
Pressing STOP, <<, or >> while playback is engaged will transmit the standard MMC Command
for the function, and cause the MIDI Beat Clock messages to stop transmitting.
