User manual ROLAND C-280P

[. . . ] When the C-280PP receives Program Change messages that include requests for Organ Tones, the [Manual] button is selected. Organ Tones are set by mean of Program Changes, and System Exclusive messages that indicate the status of Draw knobs. For more information about the System Exclusive messages that indicate the status of Draw knobs, refer to "3. Parameter Address Map.

UNIT NUMBER is always the same as the current basic channel. r Data set 1 DT1 This is the message that actually performs data transmission, and is used when you wish to transmit the data.

Checksum EOX (End Of Exclusive) If "Data Set 1" is transmitted successively, there must be an interval of at least 40 ms between packets. RPN #1 allows tuning to be specified in steps of approximately 0. 012 cents (to be precise, 100/8192 cent). Frequently used tuning values are given in the following table for your reference. Values are in hexadecimal (decimal in parentheses). +----------------+----------------+----------------------------+ |Hz at A4| cent | RPN #1 | +----------------+----------------+----------------------------+ | 445. 0 | +19. 56 | 4C 43 (+1603)| | 444. 0 | +15. 67 | 4A 03 (+1283)| | 443. 0 | +11. 76 | 47 44 (+ 964)| | 442. 0 | + 7. 85 | 45 03 (+ 643)| | 441. 0 | + 3. 93 | 42 42 (+ 322)| | 440. 0 | 0 | 40 00 ( 0)| | 439. 0 | -- 3. 94 | 3D 3D (-- 323)| | 438. 0 | -- 7. 89 | 3A 7A (-- 646)| +----------------+----------------+----------------------------+ <Example2> CE 02 CnH is the Program Change status, and n is the MIDI channel number. Since EH = 14 and 02H = 02, this is a Program Change message with MIDI CH = 15, program number 03 (Celesta in C-280PP). <Example3> B3 64 00 65 01 06 40 26 00 64 7F 65 7F BnH is the Control Change status, and n is the MIDI channel number. For Control Changes, the 2nd byte is the control number, and the 3rd byte is the value. 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. Thus, the above messages have the following meaning. B3 (B3) (B3) (B3) (B3) (B3) 64 00 65 01 06 40 26 00 64 7F 65 7F MIDI ch. 4, lower byte of RPN parameter number: 00H (MIDI ch. 4) upper byte of RPN parameter number: 01H (MIDI ch. 4) upper byte of parameter value: 40H (MIDI ch. 4) lower byte of parameter value: 00H (MIDI ch. 4) lower byte of RPN parameter number: 7FH (MIDI ch. 4) upper byte of RPN parameter number: 7FH <Example> Set the tuning of C-280PP to A4 = 442. 0 Hz Send RPN#1 to basic channel. From the above table, the value is 45 03H. 1, the message below is what should be sent.

Once the parameter number has been specified for RPN, 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. q Example of an Exclusive message and calculating a Checksum Roland Exclusive messages (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 of the transmitted exclusive message. [. . . ]
