MIDI-Implementation

❍Volume (Controller number 7)

Status 2nd byte 3rd byte

BnH 07H vvH

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

vv = Volume: 00H - 7FH (0 - 127)

* Volume messages are used to adjust the volume balance of each part.

❍Pan (Controller number 10)

Status 2nd byte 3rd byte

BnH 0AH vvH

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

vv = pan: 00H - 40H - 7FH (Left - Center - Right)

* In the rhythm part (ch.10), ignored this message.

❍Expression (Controller number 11)

Status 2nd byte 3rd byte

BnH 0BH vvH

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

vv = Expression: 00H - 7FH (0 - 127)

* Expression messages are used to adjust the level of each part.It can be used

independently from volume messages. Expression messages are used for musical

expression within a performance; e.g., crescendo and decrescendo.

❍Hold 1 (Controller number 64)

Status 2nd byte 3rd byte

nH 40H vvH

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

vv = Control value: 00H - 7FH (0 - 127) 0-63 = OFF, 64-127 = ON

* In the rhythm part (ch.10), ignored this message.

❍Effect 1(Reverb Send Level) (Controller number 91)

Status 2nd byte 3rd byte

BnH 5BH vvH

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

vv = Reverb send level: 00H - 7FH (0 - 127)

❍RPN MSB/LSB (Controller number 101, 100)

Status 2nd byte 3rd byte

BnH 65H mmH

BnH 64H llH

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

mm = upper byte of parameter number specified by RPN (MSB)

ll = lower byte of parameter number specified by RPN (LSB)

* In the rhythm part (ch.10), ignored this message.

* The value specified by RPN will not be reset even by messages such as program change

or reset all controllers.

* Regarding the RPN please refer to p. 201.

On the GM mode of TD-8, RPN can be used to modify the following parameters. Regarding

the value of each parameter, refer to Data Entry (Controller number 6, 38).

RPN

MSB LSB

Parameter

00H 00H Pitch Bend Sensitivity

00H 01H Master Fine Tuning

00H 02H Master Coarse Tuning

7FH 7FH RPN null

● Program Change

Status 2nd byte

CnH ppH

nn = MIDI channel number: 0H - FH (ch.1 - ch.16)

pp = Program number: 00H - 7FH (prog.1 - prog.128)

* The sound will change beginning with the next note-on after the program change is

received. Voices which were already sounding before the program change was received

will not be affected.

● Channel Pressure

Status 2nd byte

DnH vvH

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

vv = Channel pressure: 00H - 7FH (0 - 127)

* When channel pressure is received, the effect selected for channel pressure, in global

parameter control (p. 207), is applied.

* In the rhythm part (ch.10), ignored this message.

● Pitch Bend Change

Status 2nd byte 3rd byte

EnH llH mmH

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

mm, ll = Pitch Bend value: 00 00H - 40 00H - 7F 7FH (-8192 - 0 - +8191)

* In the rhythm part (ch.10), ignored this message.

■ Channel Mode Messages

● All Sounds Off (Controller number 120)

Status 2nd byte 3rd byte

BnH 78H 00H

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

* When this message is received, all currently-sounding notes on the corresponding

channel will be silenced. However, the status of channel messages will not change.

● Reset All Controllers (Controller number 121)

Status 2nd byte 3rd byte

BnH 79H 00H

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

* When this message is received, the following controllers will be set to their reset values.

Controller Reset value

Pitch Bend Change +/-0 (center)

Channel Key Pressure 0 (off)

Modulation 0 (off)

Expression 127 (MAX)

Hold 1 0 (off)

RPN unset; previously set data will not change

● All Notes Off (Controller number 123)

Status 2nd byte 3rd byte

BnH 7BH 00H

n = MIDI channel number: 0H - FH (ch.1 - ch.16)

* When All Notes Off is received, all notes on the corresponding channel will be turned

off. However if Hold 1 is ON, the sound will be continued until these are turned off.

■ System Realtime Message

● Active Sensing

Status

FEH

* When Active Sensing is received, the unit will begin monitoring the intervals of all

further messages. While monitoring, if the interval between messages exceeds about 420

ms, the same processing will be carried out as when All Sounds Off, All Notes Off and

Reset All Controllers are received, and message interval monitoring will be halted.

■ System Exclusive Message

* Regarding the system exclusive message refer to p. 202.

The System Exclusive Messages received by the normal mode of TD-8 are; Universal Non-

realtime System Exclusive Messages, Universal realtime System Exclusive Messages, Data

Requests (RQ1), and Data Set (DT1).
