[. . . ] Once RPN messages are received, Data Entry messages that is received at the same MIDI channel after that are recognized as changing toward the value of the RPN messages. In order not to make any mistakes, transmitting RPN Null is recommended after setting parameters you need.

Data larger than 256 bytes will be divided into packets of 256 bytes or less, and each packet will be sent at an interval of about 20 ms. 6 MIDI Implementation 3. Parameter Address Map * Transmission of "#" marked address is divided to some packets. (On GS sound generators the LSB of Pitch Bend Sensitivity is ignored, but the LSB should be transmitted anyway (with a value of 0) so that operation will be correct on any device. ) Once the parameter number has been specified for RPN or NRPN, all Data Entry messages transmitted on that same channel will be valid, so after the desired value has been transmitted, it is a good idea to set the parameter number to 7F 7FH to prevent accidents. This is the reason for the (B3) 64 7F (B3) 65 7F at the end. It is not desirable for performance data (such as Standard MIDI File data) to contain many events with running status as given in <Example 4>. This is because if playback is halted during the song and then rewound or fast-forwarded, the sequencer may not be able to transmit the correct status, and the sound generator will then misinterpret the data. Take care to give each event its own status. It is also necessary that the RPN or NRPN parameter number setting and the value setting be done in the proper order. On some sequencers, events occurring in the same (or consecutive) clock may be transmitted in an order different than the order in which they were received. For this reason it is a good idea to slightly skew the time of each event (about 1 tick for TPQN = 96, and about 5 ticks for TPQN = 480). * TPQN: Ticks Per Quarter Note * * <Example1> What is the decimal expression of 5AH? From the preceding table, 5AH = 90 <Example2> What is the decimal expression of the value 12 34H given as hexadecimal for each 7 bits?

The value of the checksum is determined by the address and data (or size) of the transmitted Exclusive message. <Example3> Getting Temporary Patch (Part 1) data (RQ1) cf. ) This operation is the same as Data Transfer function in Utility mode with "PATCH: TEMP" (Source parameter) options. [. . . ] 10H + 00H + 04H + 00H + 01H = 16 + 0 + 4 + 0 + 1 = 21 (sum) 21 (sum) ÷ 128 = 0 (quotient) . . . 21 (remainder) checksum = 128 - 21 (remainder) = 107 = 6BH This means that F0 41 10 00 53 12 10 00 04 00 01 6B F7 is the message should be sent. <Example2> Getting the data (RQ1) of PATCH MFX in PATCH:003 According to the "Parameter Address Map" (p. 7), the start address of PATCH:003 is 20 02 00 00H, and the offset address of PATCH MFX is 00 02 00H. Therefore the start address of PATCH MFX in PATCH:003 is; 20 02 00 00H 00 02 00H 20 02 02 00H (1) Exclusive Status (4) Model ID (V-Synth) (2) ID (Roland) (5) Command ID (RQ1) (3) Device ID (17) (6) End of Exclusive Calculating the checksum as shown in <Example 2>, we get a message of F0 41 10 00 53 11 10 00 00 00 00 00 7F 42 2F F7 to be transmitted. +) As the size of PATCH MFX is 00 00 01 04H, the system exclusive message should be sent is; F0 (1) 41 (2) 10 (3) 00 53 (4) 11 (5) 20 02 02 00 address 00 00 01 04 data ??
