channel and internal keyboard notes.
❍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-ch.16)
mm = upper byte of parameter number specified by RPN (MSB)
ll = lower byte of parameter number specified by RPN (LSB)
* 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 HP101, 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 - +99.99 cents),
Initial Value = 40 00H (cent)
7FH 7FH --- --- RPN null
Set condition where RPN and NRPN are unspecified. The data entry
messages after set RPN null will be ignored. (No Data entry messages
are required after RPN null).
Settings already made will not change.
mm, ll: ignored
n=MIDI channel number: 0H-FH (ch.1-ch.16)

*“A+B” means tones for dual, and “A|B” means tones for split.
* “---” and any program number other than those listed above are ignored.
* After a Program Change message is received, the sound will change beginning with the
next Note-on. Voices already sounding when the Program Change message was
received will not be affected.
* Received program change messages through channel 1-16 affect each part individually.
* Received program change messages through basic channel affect part on the
corresponding channel and internal keyboard notes.
