Midi Data Format - Yamaha YPP-100 Light Piano Owner's 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 YPP-100.
1. NOTE ON/OFF
Data format: [9nH] -> [kk] -> [vv]
9nH = Note ON/OFF event (n = channel number)
kk = Note number (Transmit: 10H ~ 73H = E-1 ~ G7 /
Receive: 00H ~ 7FH = C-2 ~ G8)*
vv = Velocity (Key ON = 01H ~ 7FH, Key OFF = 00H)
Data format: [8nH] -> [kk] -> [vv]
8nH = Note OFF event (n = channel number)
kk = Note number: 00H ~ 7FH = C-2 ~ G8
vv = Velocity
* If received value exceeds the supported range for the selected
voice, the note is adjusted by the necessary number of octaves.
2. CONTROL CHANGE
Data format: [BnH] -> [cc] -> [vv]
BnH = Control change (n = channel number)
cc = Control number

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
Switches off all sound from the channel. Does not reset Note On
and Hold On conditions established by Channel Messages.
(2) Reset All Controllers

(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 specified
channel. Any notes being held by the damper or sostenuto 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

• When control change reception is turned OFF in the Function
mode, control change data will not be transmitted or received
except for Bank Select and Mode messages.
• 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.
• The Multi-timbre and Poly modes are always active. No change
occurs when OMNI ON, OMNI OFF, MONO, or POLY mode
messages are received.
