[. . . ] 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. This device receives the following RPNs.

System Realtime Messages Active Sensing Status FEH * * This message is transmitted at intervals of approximately 250 msec. A 7-bit byte can express data in the range of 128 steps. For data where greater precision is required, we must use two or more bytes. For example, two hexadecimal numbers aa bbH expressing two 7-bit bytes would indicate a value of aa x 128+bb. In the case of values which have a +/- sign, 00H = -64, 40H = +/-0, and 7FH = +63, so that the decimal expression would be 64 less than the value given in the above chart. In the case of two types, 00 00H = -8192, 40 00H = +/-0, and 7F 7FH = +8191. For example, if aa bbH were expressed as decimal, this would be aa bbH - 40 00H = aa x 128+bb - 64 x 128. Data marked "Use nibbled data" is expressed in hexadecimal in 4-bit units. A value expressed as a 2-byte nibble 0a 0bH has the value of a x 16+b. Examples of Actual MIDI Messages <Example1> 92 3E 5F 9n is the Note-on status, and n is the MIDI channel number. Since 2H = 2, 3EH = 62, and 5FH = 95, this is a Note-on message with MIDI CH = 3, note number 62 (note name is D4), and velocity 95. <Example2> CE 49 CnH is the Program Change status, and n is the MIDI channel number. Since EH = 14 and 49H = 73, this is a Program Change message with MIDI CH = 15, program number 74. <Example3> EA 00 28 EnH is the Pitch Bend Change status, and n is the MIDI channel number. The 2nd byte (00H = 0) is the LSB and the 3rd byte (28H = 40) is the MSB, but Pitch Bend Value is a signed number in which 40 00H (= 64 x 12+80 = 8192) is 0, so this Pitch Bend Value is 28 00H - 40 00H = 40 x 12+80 - (64 x 12+80) = 5120 - 8192 = -3072 If the Pitch Bend Sensitivity is set to 2 semitones, -8192 (00 00H) will cause the pitch to change -200 cents, so in this case -200 x (-3072) ÷ (-8192) = -75 cents of Pitch Bend is being applied to MIDI channel 11. <Example4> B3 64 00 65 00 06 0C 26 00 64 7F 65 7F BnH is the Control Change status, and n is the MIDI channel number.

From the preceding table, 5AH = 90 <Example2> What is the decimal expression of the value 12 34H given as hexadecimal for each 7 bits?

From the preceding table, since 0AH = 10, 03H = 3, 09H = 9, 0DH = 13 ((10 x 16+3) x 16+9) x 16+13 = 41885 <Example4> What is the nibbled expression of the decimal value 1258? 16 ) 1258 16 ) 78 . . . 10 16 ) 4 . . . 14 0 . . . 4 Since from the preceding table, 0 = 00H, 4 = 04H, 14 = 0EH, 10 = 0AH, the result is: 00 04 0E 0AH. 25 Example of an Exclusive Message and Calculating a Checksum Roland Exclusive messages (RQ1, DT1) are transmitted with a checksum at the end (before F7) to make sure that the message was correctly received. The value of the checksum is determined by the address and data (or size) of the transmitted Exclusive message. Example Settings Note name Equal Temperament C 0 C# 0 D 0 Eb 0 E 0 F 0 F# 0 G 0 G# 0 A 0 Bb 0 B 0 Just Temperament (Key-tone C) 0 -8 +4 +16 -14 -2 -10 +2 +14 -16 +14 -12 Arabian Scale 6 +45 -2 -12 -51 -8 +43 -4 +47 0 -10 -49 How to calculate the checksum (hexadecimal numbers are indicated by "H") The checksum is a value derived by adding the address, size, and checksum itself and inverting the lower 7 bits. Here's an example of how the checksum is calculated. [. . . ]
