MIDI Data Format

If you’re already very familiar with MIDI, or are using a computer to control your music hardware with computer-generated

MIDI messages, the data provided in this section can help you to control the CP33.

1. NOTE ON/OFF

Data format: [9nH] -> [kk] -> [vv]

9nH = Note ON/OFF event (n = channel number)

kk = Note number (Transmit: 09H ~ 78H = A-2 ~ C8 /

Receive: 00H ~ 7FH = C-2 ~ G8)

vv = Velocity (Key ON = 01H ~ 7FH, Key OFF = 00H)

Data format: [8nH] -> [kk] -> [vv] (reception only)

8nH = Note OFF event (n = channel number)

kk = Note number: 00H ~ 7FH = C-2 ~ G8)

vv = Velocity

2. CONTROL CHANGE

Data format: [BnH] -> [cc] -> [vv]

BnH = Control change (n = channel number)

cc = Control number

vv = Data Range

(1) Bank Select

ccH Parameter Data Range (vvH)

00H Bank Select MSB 00H:Normal

20H Bank Select LSB 00H...7FH

Bank selection processing does not occur until receipt of next

Program Change message.

(2) Modulation wheel

ccH Parameter Data Range (vvH)

01H Modulation 00H...7FH

(3) Main Volume

ccH Parameter Data Range (vvH)

07H Volume MSB 00H...7FH

(4) Expression

ccH Parameter Data Range (vvH)

0BH Expression MSB 00H...7FH

(5) Pan

ccH Parameter Data Range (vvH)

0AH Pan 00H...7FH

(6) Sustain

ccH Parameter Data Range (vvH)

40H Sustain MSB 00H...7FH

(7) Sostenuto

ccH Parameter Data Range (vvH)

42H Sostenuto 00H-3FH:off, 40H-7FH:on

(8) Soft Pedal

ccH Parameter Data Range (vvH)

43H Soft Pedal 00H-3FH:off, 40H-7FH:on

(9) Effect1 Depth (Reverb Send Level)

ccH Parameter Data Range (vvH)

5BH Effect1 Depth 00H...7FH

Adjusts the reverb send level.

(10)Effect4 Depth (Variation Effect Send Level)

ccH Parameter Data Range (vvH)

5EH Effect4 Depth 00H...7FH

(11)RPN

65H RPN MSB

64H RPN LSB

06H Data Entry MSB

26H Data Entry LSB

60H Data Increment

61H Data Decrement

* Parameters that are controllable with RPN

• Coarse Tune

• Fine Tune

• Pitch Bend Range

3. MODE MESSAGES

Data format: [BnH] -> [cc] -> [vv]

BnH = Control event (n = channel number)

cc = Control number

vv = Data Range

(1) All Sound Off

ccH Parameter Data Range (vvH)

78H All Sound Off 00H

(2) Reset All Controllers

ccH Parameter Data Range (vvH)

79H Reset All Controllers 00H

Resets controllers as follows.

Controller Value

Expression 127 (max)

Sustain Pedal 0 (off)

Sostenuto 0 (off)

Soft Pedal 0 (off)

(3) Local Control (reception only)

ccH Parameter Data Range (vvH)

7AH Local Control 00H (off), 7FH (on)

(4) All Notes Off

ccH Parameter Data Range (vvH)

7BH All Notes Off 00H

Switches OFF all the notes that are currently ON on the spec-

iﬁed channel. Any notes being held by the sustain or soste-

nuto pedal will continue to sound until the pedal is released.

(5) Omni Off (reception only)

ccH Parameter Data Range (vvH)

7CH Omni Off 00H

Same processing as for All Notes Off.

(6) Omni On (reception only)

ccH Parameter Data Range (vvH)

7DH Omni On 00H

Same processing as for All Notes Off.

(7) Mono (reception only)

ccH Parameter Data Range (vvH)

7EH Mono 00H

Same processing as for All Sound Off.

(8) Poly (reception only)

ccH Parameter Data Range (vvH)

7FH Poly 00H

Same processing as for All Sound Off.

• When Control Change is turned OFF, Control Change mes-

sages will not be transmitted or received.

• Local on/off, OMNI on/off are not transmitted. (The appropriate

note off number is supplied with “All Note Off” transmission).

• When a voice bank MSB/LSB is received, the number is

stored in the internal buffer regardless of the received order,

then the stored value is used to select the appropriate voice

when a program change message is received.

•Poly mode is always active. This mode will not change when

the instrument receives MONO/POLY mode message.
