Control Change
— This feature sends
data on various controllers, each having
its own number. For the details of each
parameter, see “MIDI Data” on Page 42.
Program Change
— This feature
changes the preset sounds. Each sound
number corresponds to a program num-
ber between 0 and 127.
System Exclusive
— This feature
sends special signals unique to the MD-
1200. For details, see “MIDI Data” on
Page 42.
System Real Time
— “Clock” is like a
metronome to send the synchronizing
signal.
System real time commands send three
kinds of signals —
start
tells the key-
board to start playing from the begin-
ning,
stop
tells all the synchronized
instruments to stop playing, and
contin-
ue
is similar to start, but it signals the
music to begin at whatever point it was
last stopped.
All Notes Off
— This feature is a kind of
panic button: it stops the sounds cur-
rently playing. The MD-1200 only re-
ceives this message.
Active Sensing
— This means the MD-
1200’s sound turns off in the event the
connection cable to
MIDI IN
terminal is
accidentally disconnected.
