MIDI Implementation

❍General Purpose Controller 6 (Controller number 81) (Rotary Brake)

Status 2nd byte 3rd byte

BnH 51H vvH

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

vv = control value: 00H - 7FH (0 - 127) 0-63 = SPIN, 64-127 = BRAKE

* When signals are received through the MIDI IN connector, reception is over the channel

specified in CONTROL MIDI CH. (p. 77) (factory setting: Channel 1).

* Not received by the Orchestral Tones part.

* Not received when MIDI GENERAL CONTROLLERS SWITCH (p. 76) is OFF.

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

Status 2nd byte 3rd byte

BnH 65H mmH

BnH 64H llH

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

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

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

<<< RPN >>>

Control Changes include RPN (Registered Parameter Numbers), which are extended. When

using RPNs, first RPN (Controller numbers 100 and 101; they can be sent in any order)

should be sent in order to select the parameter, then Data Entry (Controller numbers 6 and

38) should be sent to set the value. Once RPN messages are received, Data Entry messages

that is received at the same MIDI channel after that are recognized as changing toward the

value of the RPN messages. In order not to make any mistakes, transmitting RPN Null is

recommended after setting parameters you need.

This device receives the following RPNs.

RPN Data entry

MSB, LSB

MSB, LSB Notes

00H, 00H mmH, llH Pitch Bend Sensitivity

mm: 00H - 18H (0 - 24 semitones)

ll: ignored (processed as 00H)

Up to 2 octave can be specified in semitone steps.

* Not received by the Organ part.

00H, 01H mmH, llH Master Fine Tuning

mm, ll: 20 00H - 40 00H - 60 00H (-8192 x 50 /

8192 - 0 - +8192 x 50 / 8192 cent)

* Not received by the Organ part.

00H, 02H mmH, llH Master Coarse Tuning

mm: 10H - 40H - 70H (-48 - 0 - +48 semitones)

ll: ignored (processed as 00H)

* Not received by the Organ part.

7FH, 7FH ---, --- RPN null

RPN and NRPN will be set as “unspecified.”

Once this setting has been made, subsequent

Parameter values that were previously set will

not change.

mm, ll: ignored

●Program Change

Status 2nd byte

CnH ppH

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

pp = program number: 00H - 3FH (prog.1 - prog.64) (registration)

00H - 07H (prog.1 - prog.8) (Orchestral Tones)

* Not received when MIDI PROGRAM CHANGE SWITCH is OFF (factory setting: ON).

* Registrations are received on the channel specified by CONTROL MIDI CH. (p. 77)

(factory setting: channel 1). The Orchestral Tones part is received on the channel

specified by ORCHESTRAL TONES MIDI CH. (factory setting: Upper Orchestral Tones

=channel 4, Lower Orchestral Tones = channel 5, Pedal Orchestral Tones = channel 6).

●Channel Pressure

Status 2nd byte

DnH vvH

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

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

* Received only for the Orchestral Tones Part.

●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)

* Received only for the Orchestral Tones Part.

■Channel Mode messages

●All Sound 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 notes currently sounding on the corresponding

channel will be turned off.

●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)

Modulation 0 (off)

Hold 1 0 (off)

●All Note Off (Controller number 123)

Status 2nd byte 3rd byte

BnH 7BH 00H

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

* When All Note Off is received, all currently sounding notes of the corresponding

channel will be turned off. However if Hold 1 is on, the sound will be held until these are

turned off.

■System Realtime Messages

●Active Sensing

Status

FEH

* When an Active Sensing message is received, the unit will begin monitoring the interval

at which MIDI messages are received. During monitoring, if more than 420 ms passes

without a message being received, the same processing will be done as when All Sound

Off, All Note Off, and Reset All Controllers messages are received. Then monitoring will

be halted.

■System Exclusive Messages

Status data byte Status

F0H iiH, ddH, ......, eeH F7H

F0H: System Exclusive message status

ii = ID number: This is the ID number (manufacturer ID) that specifies the

manufacturer whose exclusive message this is. Roland’s manufacturer

ID is 41H.ID numbers 7EH and 7FH are defined in an expansion of the

MIDI standard as Universal Non-realtime messages (7EH) and

Universal Realtime Messages (7FH).

dd,..., ee = data: 00H - 7FH (0 - 127)

F7H: EOX (End Of Exclusive) This is the last status of system exclusive

message.

The System Exclusive Messages received by VK-88 are; messages related to mode settings,

Universal Realtime System Exclusive messages, Data Requests (RQ1), and Data Set (DT1).

●Universal Non-realtime System Exclusive Messages

❍Identity Request Message

Status Data byte Status

F0H 7EH, dev, 06H, 01H F7H

Byte Explanation

FOH Exclusive status

7EH ID number (universal non-realtime message)

dev Device ID (dev: 10H (17) fixed)

06H Sub ID#1 (General Information)

01H Sub ID#2 (Identity Request)

F7H EOX (End Of Exclusive)

* The “dev” is own device number or 7FH (Broadcast)
