User manual ROLAND HP-147R V1.00 MIDI IMPLEMENTATION

[. . . ] 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. [. . . ] UNIT NUMBER is always the same as the current MIDI Tx/Rx channel. n = MIDI channel number: 0H-FH (ch. 1-ch. 16) vv = Control value: 00H, 7FH (0, 127) 0 = OFF, 127 = ON Soft (Controller number 67) Status BnH 2nd byte 43H 3rd byte vvH Data set 1 DT1 This is the message that actually performs data transmission, and is used when you wish to transmit the data.

After sending the master fine tune, immediately the RPN Null shall be sent.

Checksum EOX (End Of Exclusive) Regarding the address please refer to "3. Parameter Address Map. " Regarding the checksum please refer to "4. Supplementary material. " System Realtime Message Active sensing Status FEH * This will be transmitted constantly at intervals of approximately 210 msec. 3. Parameter Address Map (Model ID = 1AH) All the numbers of address, size, Data, and Default Value are indicated in 7-bit Hexadecimal-form. For data where greater precision is required, we must use two or more bytes. [. . . ] In a case in which two or more messages consecutive messages have the same status, MIDI has a provision called "running status" which allows the status byte of the second and following messages to be omitted.
