YPP-100
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
Switches off all sound from the channel. Does not reset Note On
and Hold On conditions established by Channel Messages.
(2) Reset All Controllers
ccH Parameter Data Range (vvH)
79H
Reset All Controllers
00H
Resets controllers as follows.
Controller Value
Expression 127 (max)
Damper 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 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 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 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.
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] (reception only)
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
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.

(5) Sostenuto (reception only)
ccH Parameter Data Range (vvH)
42H Sostenuto 00H-3FH:off, 40H-7FH:on
(6) Soft Pedal
ccH Parameter Data Range (vvH)
43H Soft Pedal 00H-3FH:off, 40H-7FH:on
