MIDI 3-2 Channel Messages 3-2-1 Note On/Off Messages which are generated when the keyboard is played: „ Note On: Generated when a key is pressed. „ Note Off: Generated when a key is released. Each message includes a specific note number, which corresponds to the key that is pressed, plus a Velocity value based on how hard the key is struck. Reception note range = C -2 (0) - G8 (127), C3 = 60 Velocity range = 1 - 127 (only the Note On Velocity is received) 3-2-2 Pitch Bend Pitch Bend messages are continuous controller messages that allow the pitch of designated notes to be raised or lowered by a specified amount over a specified duration. This message is a numerical representation of pitch bend wheel position. 3-2-3 Program Change Messages that determine which Voice to select for each part. In combination with Bank Select, you can select not only basic Voice numbers, but also variation Voice bank numbers. When you specify Program Change as a number in the range of 0 - 127, specify a number that is one less than the program number listed in the Voice List. For example, to specify program number 128, you would actually enter Program Change 127. 3-2-4 Control Change Control Change messages let you select a Voice bank, control volume, panning, modulation, portamento time, brightness, and various other controller parameters, through specific Control Change numbers. Each Control Change number corresponds to a specific parameter. Bank Select MSB (Control #0) and Bank Select LSB (Control #32) Messages that select variation Voice bank numbers by combining and sending the MSB and LSB from an external device. The functions of MSB and LSB messages differ depending on the tone generator mode: „ MSB numbers select Voice Type (Normal Voice or Drum Voice); „ LSB numbers select Voice banks. A new bank selection will not become effective until the next Program Change message is received. To change the Voices (including the Voice banks), transmit Bank Select MSB, LSB, then Program Change in this order as a set. Modulation (Control #1) Messages that control vibrato depth using the Modulation Wheel. „ 127: Maximum vibrato. „ 0: Vibrato off. 68

Note On: Generated when a key is pressed.
Note Off: Generated when a key is released.
Each message includes a specific note number, which corresponds to the key that is pressed,
plus a Velocity value based on how hard the key is struck.
Reception note range = C -2 (0) - G8 (127), C3 = 60
Velocity range = 1 - 127 (only the Note On Velocity is received)

Pitch Bend
Pitch Bend messages are continuous controller messages that allow the pitch of designated
notes to be raised or lowered by a specified amount over a specified duration.
This message is a numerical representation of pitch bend wheel position.
3-2-3
Program Change
Messages that determine which Voice to select for each part. In combination with Bank Select,
you can select not only basic Voice numbers, but also variation Voice bank numbers.
3-2-4
Control Change
Control Change messages let you select a Voice bank, control volume, panning, modulation,
portamento time, brightness, and various other controller parameters, through specific Control
Change numbers. Each Control Change number corresponds to a specific parameter.
When you specify Program Change as a number in the range of 0 - 127, specify a
number that is one less than the program number listed in the Voice List. For
example, to specify program number 128, you would actually enter Program Change
127.
Bank Select MSB
(Control #0) and
Bank Select LSB
(Control #32)
Messages that select variation Voice bank numbers by combining and
sending the MSB and LSB from an external device.
The functions of MSB and LSB messages differ depending on the tone
generator mode:
MSB numbers select Voice Type (Normal Voice or Drum Voice);
LSB numbers select Voice banks.
A new bank selection will not become effective until the next Program
Change message is received.
To change the Voices (including the Voice banks), transmit Bank Select
MSB, LSB, then Program Change in this order as a set.
Modulation (Control
#1)
Messages that control vibrato depth using the Modulation Wheel.
127
: Maximum vibrato.
0
: Vibrato off.
