Midi Data Format - Yamaha CP33 Service Manual

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

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
78H All Sound Off
(2) Reset All Controllers
ccH Parameter
79H Reset All Controllers
Resets controllers as follows.
Controller
Expression
Sustain Pedal
Sostenuto
Soft Pedal
(3) Local Control (reception only)
ccH Parameter
7AH Local Control
(4) All Notes Off
ccH Parameter
7BH All Notes Off
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
7CH Omni Off
Same processing as for All Notes Off.
(6) Omni On (reception only)
ccH Parameter
7DH Omni On
Same processing as for All Notes Off.
(7) Mono (reception only)
ccH Parameter
7EH Mono
Same processing as for All Sound Off.
(8) Poly (reception only)
ccH Parameter
7FH Poly
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.
