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

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

* Note numbers outside the range of 15-113 are transposed to the nearest octave within

this range.

notes.

* Received chorus messages through basic channel affect part on the corresponding

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)

vv=Control value: 00H-7FH (0-127) 0-63 = OFF 64-127 = ON

* These message can affect only MIDI notes.

*“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.
