3D (decimal 61) is sent as the key number,
finally 21 (decimal 33) is sent as velocity.
Pitch Bender — The keyboard sends and
receives pitch bending signals.
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 39.
Program Change — This feature changes
the preset sounds. Each sound number cor-
responds to a program number between 0
and 127.
System Exclusive — This feature sends
special signals unique to the keyboard. For
details, see “MIDI Data” on Page 39.
System Real Time — “Clock” is like a metro-
nome to send the synchronizing signal.
System real time commands send three
kinds of signals —
start tells the keyboard to
start playing from the beginning,
stop tells all
the synchronized instruments to stop play-
ing, and
continue is similar to start, but it sig-
nals 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 currently
playing. The keyboard only receives this
message.
Active Sensing — This means the key-
board’s sound turns off in the event the con-
nection cable to
MIDI IN
terminal is
accidentally disconnected.
