Chapter 8. Appendix
188
This unit implements additional functionality and parameters over and above the
SC-88, which itself was an expansion of the GS sound source format. These func-
tions and parameters are marked by a [Pro] symbol. If MIDI messages marked by a
[Pro] symbol are transmitted to another GS format sound source or to the SC-88,
those messages may not be recognized. Also, functions and parameters which were
added to the SC-88 over and above previous GS format sound sources are marked
by an [88] symbol.
Section 1. Receive data
■ Channel Voice Messages
● Note off
Status 2nd byte 3rd byte
8nH kkH vvH
9nH kkH 00H
n = MIDI channel number : 0H-FH (ch.1-ch.16)
kk = note number : 00H-7FH (0-127)
vv = note off velocity : 00H-7FH (0-127)
* For Drum Parts, these messages are received when Rx.NOTE OFF = ON for each
Instrument.
* The velocity values of Note Off messages are ignored.
● Note on
Status 2nd byte 3rd byte
9nH kkH vvH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
kk = note number : 00H-7FH (0-127)
vv = note on velocity : 01H-7FH (1-127)
* Not received when Rx.NOTE MESSAGE = OFF. (Initial value is ON)
* For Drum Parts, not received when Rx.NOTE ON = OFF for each Instrument.
● Polyphonic Key Pressure
Status 2nd byte 3rd byte
AnH kkH vvH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
kk = note number : 00H-7FH (0-127)
vv = key pressure : 00H-7FH (0-127)
* Not received when Rx.POLY PRESSURE (PAf) = OFF. (Initial value is ON)
* The resulting effect is determined by System Exclusive messages. With the initial
settings, there will be no effect.
● Control Change
* When Rx.CONTROL CHANGE = OFF, all control change messages except for
Channel Mode messages will be ignored.
* The value specified by a Control Change message will not be reset even by a
Program Change, etc.
❍ Bank Select (Controller number 0, 32) [88]
Status
2nd byte 3rd byte
BnH 00H mmH
BnH 20H llH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
mm = Bank number MSB : 00H-7FH (GS Variation number 0 - 127), Initial
Value = 00H
ll = Bank number LSB : 00H - 03H (MAP), Initial Value = 00H
* Not received when Rx.BANK SELECT = OFF. "Rx.BANK SELECT" is set to OFF
by "Turn General MIDI System On," and set to ON by "GS RESET." (Power-on
default value is ON.)
* When Rx.BANK SELECT LSB = OFF, Bank number LSB will be handled as 00H
regardless of the received value. However, when sending Bank Select messages,
you have to send both the MSB (mmH) and LSB (llH, the value should be 00H)
together.
* Bank Select processing will be suspended until a Program Change message is
received.
* The GS format "Variation number" is the value of the Bank Select MSB (Controller
number 0) expressed in decimal.
* This unit recognizes the Bank Select LSB (Controller number 32) as a flag for
switching between the Native MAP,SC-88MAP and the SC-55MAP. With a Bank
Select LSB of 00H, the map selected by the front panel SC-88MAP or SC-55MAP
button will be selected. With a LSB of 01H, the SC-55MAP will be selected. With a
LSB of 02H, the SC-88MAP will be selected.
With a LSB of 03H, the Native MAP will be selected.
* Some other GS devices do not recognize the Bank Select LSB (Controller number
32).
❍ Modulation (Controller number 1)
Status 2nd byte 3rd byte
BnH 01H vvH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
vv = Modulation depth : 00H-7FH (0-127)
* Not received when Rx.MODULATION = OFF. (Initial value is ON)
* The resulting effect is determined by System Exclusive messages. With the initial
settings, this is Pitch Modulation Depth.
❍ Portamento Time (Controller number 5)
Status 2nd byte 3rd byte
BnH 05H vvH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
vv = Portamento Time : 00H-7FH (0-127), Initial value = 00H (0)
* This adjusts the rate of pitch change when Portamento is ON or when using the
Portamento Control. A value of 0 results in the fastest change.
❍ Data Entry (Controller number 6, 38)
Status
2nd byte 3rd byte
BnH 06H mmH
BnH 26H llH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
mm, ll = the value of the parameter specified by RPN/NRPN
mm = MSB, ll = LSB
❍ 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), Initial Value = 64H (100)
* Volume messages are used to adjust the volume balance of each Part.
* Not received when Rx.VOLUME = OFF. (Initial value is ON)
❍ 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), Initial Value
= 40H (Center)
* For Rhythm Parts, this is a relative adjustment of each Instrument's pan setting.
* Not received when Rx.PANPOT = OFF. (Initial value is ON)
❍ 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), Initial Value = 7FH (127)
* This adjusts the volume of a Part. It can be used independently from Volume mes-
sages. Expression messages are used for musical expression within a performance;
e.g., expression pedal movements, crescendo and decrescendo.
* Not received when Rx.EXPRESSION = OFF. (Initial value is ON)
❍ Hold 1 (Controller number 64)
Status
2nd byte
3rd byte
BnH 40H vvH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
vv = Control value : 00H-7FH (0-127)
* Not received when Rx.HOLD1 = OFF. (Initial value is ON)
❍ Portamento (Controller number 65)
Status 2nd byte 3rd byte
BnH 41H vvH
n = MIDI channel number : 0H-FH (ch.1-ch.16)
vv = Control value : 00H-7FH (0-127) 0-63 = OFF, 64-127 = ON
* Not received when Rx.PORTAMENTO = OFF. (Initial value is ON)
