❍Effect 2(Tremolo Depth) (Controller number 92)
Status 2nd byte 3rd byte
BnH 5CH vvH
n = MIDI channel number: 0H - FH (ch.1 - ch.16)
vv = Control value: 00H - 7FH (0 - 127)
* Only the pad part and the percussion parts can be received.
* This is used as the data of the [LFO FLT/AMP] knob.
* When recording, this is recorded in the sequencer data itself.
❍Effect 4(Celeste Depth) (Controller number 94)
Status 2nd byte 3rd byte
BnH 5EH 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 melody parts and the percussion parts, it is used as the multi effects switch of the
sequencer pattern data.
* In the pad part, it is used as the data of the [MULTI EFFECTS] button.
* When recording, this is recorded in the sequencer data itself if it is received on the pad
part or the percussion parts.
❍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)
* Only the channel assigned to the melody part can be received.
* The value specified by RPN will not be reset even by messages such as program change
or reset all controllers.
* Not recorded in the sequencer.
**RPN**
The RPN (Registered Parameter Number) messages are expanded control changes,and each
function of an RPN is described by the MIDI Standard.
To use these messages, you must first use RPN (controller number 100 and 110, their order
does not matter) to specify the parameter to be controlled, and then use Data Entry
messages (controller number 6, 38) to specify the value of the specified parameter. Once an
RPN parameter has been specified, all data entry messages received on that channel will
modify the value of that parameter. To prevent accidents, it is recommended that you set
RPN null (RPN number = 7FH 7FH) when you have finished setting the value of the desired
parameter. Refer to "Examples of actual MIDI messages" <Example 4> (p. 109).
On the normal mode of HPD-15, RPN can be used to modify the following parameters.
Regarding the value of each parameter, refer to Data Entry (Controller number 6).
RPN
mm ll Parameter
00H 00H Pitch Bend Sensitivity
7FH 7FH RPN null
●Program Change
Status 2nd byte
CnH ppH
n = 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.
* Not recorded in the sequencer.
●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 melody parts, it is used as the part pitch bend change of the sequencer pattern
data.
* In the pad part or the percussion parts, it is used as the data of the [PITCH] knob.
* When recording, this is recorded in the sequencer data itself.
■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.
* Not recorded in the sequencer.
●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.
* When recording, a control message carrying the reset value will be created and recorded.
Controller Reset value
Pitch Bend Change +/-0 (center)
Polyphonic Key Pressure 0 (off)
Modulation 0 (off)
Foot Control 0 (off)
General Purpose Controller 1 0 (off)
General Purpose Controller 2 0 (off)
General Purpose Controller 6 0 (off)
General Purpose Controller 7 0 (off)
General Purpose Controller 8 0 (off)
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.
* In the recording mode, “Note OFF message” will be created for corresponding Note ON
message, and will be recorded.
