The value specified by RPN will not be reset even by messages such as Program Change or Reset All Controller.

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

RPN messages are recognized only when received on the basic channel.

kk = note number: 00H-7FH (0-127) vv = note off velocity: 00H-7FH (0-127)

**RPN** The RPN (Registered Parameter Number) messages are expanded control changes, and each

function of an RPN is described by the MIDI Standard.

Status 2nd byte 3rd byte

To use these messages, you must first use RPN MSB and RPN LSB messages to specify the

9n H kk H vv H

parameter to be controlled, and then use Data Entry messages to specify the value of the specified parameter. Once an RPN parameter has been specified, all Data Entry messages

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

received on that channel will modify the value of that parameter. To prevent accidents, it is

kk = note number: 00H-7FH (0-127)

recommended that you set RPN Null (RPN Number = 7FH/7FH) when you have finished

vv = note on velocity: 01H-7FH (1-127)

setting the value of the desired parameter.

Note numbers outside the range of 11-106 are transposed to the nearest octave within

On the C-80, RPN can be used to modify the following parameters.

this range. Transpose function does not affect the recognized note numbers.

n = MIDI channel number: 0H-FH (ch.1-ch.16) mm, ll = the value of the parameter specified by RPN

Data entry messages are recognized only when received on the basic channel.

❍Volume (Controller number 7) Status 2nd byte 3rd byte Bn H 07H vv H

n = MIDI channel number: 0H-FH (ch.1-ch.16) vv = Volume: 00H-7FH (0-127), Initial Value = 7FH (127)

Received volume messages affect received note event levels, and cannot affect internal keyboard notes.

❍Expression (Controller number 11) Status 2nd byte 3rd byte Bn H 0BH vv H

n = MIDI channel number: 0H-FH (ch.1-ch.16) vv = Expression: 00H-7FH (0-127), Initial Value = 7FH (127)

These message can affect only MIDI notes.

❍Hold 1 (Controller number 64) Status 2nd byte 3rd byte Bn H 40H vv H

n = MIDI channel number: 0H-FH (ch.1-ch.16) vv = Control value: 00H-7FH (0-127) 0-63 = OFF, 64-127 = ON

These message can affect only MIDI notes.
