Midi Implementation - Roland SCB-55 Owner's Manual

GS DAUGHTER BOARD
Model : SCB-55
1. RECEIVE DATA
* MIDI messages required for responding to General MIDI System Level 1
specifications are marked with a
[Channel Voice Messages]
<1> NOTE OFF
Status Second Third
8nH kkH vvH
9nH kkH 00H
n=MIDI channel number
kk=Note number
vv=Velocity
* In the drum part, recognized when "Rx.NOTE OFF = ON" for each instru-
ment.
* Velocity is ignored.
<2> NOTE ON
Status Second Third
9nH kkH vvH
n=MIDI channel number
kk=Note number
vv=Velocity
* Ignored when "Rx.NOTE MESSAGE = OFF."
* In the drum part, ignored when "Rx.NOTE ON = OFF" for each instrument.
<3> POLYPHONIC KEY PRESSURE
Status Second Third
AnH kkH vvH
n=MIDI channel number
kk=Note number
vv=Value
* Ignored when "Rx.POLY PRESSURE (PAf) = OFF."
* Effect to the parameter set on System Exclusive Messages.
The default setting has no effect.
<4> CONTROL CHANGE
* Ignores all control change messages (other than channel mode messages)
when "Rx.CONTROL CHANGE = OFF."
* The values set by Control change messages won't be reset by receiving
new Program change messages.
(1) Bank select (Controller number 0, 32)
Status Second Third
BnH 00H mmH
BnH 20H llH
n=MIDI channel number
mm,ll=Bank number
* Ignored 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.)
* The LSB 7-bits are ignored (always regards as llH=00H) in this Model.
However, when sending Bank Select messages, you have to send both the
MSB (mm) and LSB (ll) together.
* "Bank select" is suspended until receiving "Program change." To select a
Tone of another bank, you have to send a Bank select (mm,ll) before send-
ing the Program change.
* The "Variation number" of GS Format is defined as the decimal expression
of the MSB value (Control change number 00H) of the Bank select.

(2) Modulation (Controller number 1)
Status Second Third
BnH 01H vvH
n=MIDI channel number
vv=Modulation depth
* Ignored when "Rx.MODULATION = OFF."
* Effect to the parameter set on System Exclusive Messages.
The default setting is pitch modulation depth.
(3) Portamento time (Controller number 5)
Status Second Third
BnH 05H vvH
n=MIDI channel number
vv=Portamento time
* The Portamento time value changes the rate of pitch change when
Portamento is ON or when using portamento control messages.
Value 0 is the fastest.
(4) Data entry (Controller number 6, 38)
Status Second Third
BnH 06H mmH
BnH 26H llH
n=MIDI channel number
mm,ll=Value of the parameter specified with RPN and/or NRPN
(5) Volume (Controller number 7)
Status Second Third
BnH 07H vvH
n=MIDI channel number
vv=Volume
* Volume messages control the volume level of the specified channel (part).
Use Volume messages to control volume balance of each part.
* Ignored when "Rx.VOLUME = OFF."
(6) Panpot (Controller number 10)
Status Second Third
BnH 0AH vvH
n=MIDI channel number
vv=Panpot
* 127 steps from Left to Center to Right.
* Within the Drum Part, the Panpot provides overall control of a stereophon-
ic image.
* Ignored when "Rx.PANPOT = OFF."
(7) Expression (Controller number 11)
Status Second Third
BnH 0BH vvH
n=MIDI channel number
vv=Expression
* Expression and Volume messages are cumulative, and the result will con-
trol the overall volume.
Use Expression messages for expression pedal, or creating expressive
effects, such as crescendo, decrescendo, while playing.
* Ignored when "Rx.EXPRESSION = OFF."
