n=MIDI channel number: 0H - FH (ch.1 - ch.16) mm=upper byte of parameter number specified by RPN ll=lower byte of parameter number specified by RPN
* The value specified by RPN will not be reset even by messages such as Program Change
or Reset All Controller.
** 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 MSB and RPN LSB messages to specify the 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 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.
On the ep-70/90, RPN can be used to modify the following parameters.
RPN Data entry MSB LSB MSB LSB Explanation 00H 01H mmH llH Master Fine Tuning
mm,ll: 00 00H - 40 00H - 7F 7FH (-100 - 0 - +99.9 cents)
7FH 7FH --- --- RPN null
Set condition where RPN is unspecified. Settings already made will not change. mm,ll: ignored
n=MIDI channel number: 0H - FH (ch.1 - ch.16) vv=Control value: 00H - 7FH (0 - 127) 0-63=OFF, 64-127=ON
