**RPN**

1. Receive data

The RPN (Registered Parameter Number) messages are expanded control changes, and each function of an RPN is described by the MIDI Standard.

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

parameter to be controlled, and then use Data Entry messages to specify the value of the

Note off specified parameter. Once an RPN parameter has been specified, all Data Entry messages Status 2nd byte 3rd byte received on that channel will modify the value of that parameter. To prevent accidents, it is 8n H kk H vv H recommended that you set RPN Null (RPN Number = 7FH/7FH) when you have finished 9n H kk H 00H setting the value of the desired parameter.

On the C-280, RPN can be used to modify the following parameters.

n = MIDI channel number: 0H-FH (ch.1-ch.16) kk = note number: 00H-7FH (0-127) RPN Data entry vv = note off velocity: 00H-7FH (0-127) MSB LSB MSB LSB Explanation

The switch to the requested Ensemble Tone is made when the first new Note On message arrives after the Program Change has been received. Organ Tones are changed

The value specified by RPN will not be reset even by messages such as Program Change or Reset All Controller. RPN messages are recognized only when received on the basic channel.
