While monitoring, if the interval between messages exceeds 360 msec, the same processing will be carried out as when All Notes Off and Reset All Controllers are received, and message interval monitoring will be halted. n = MIDI channel number : 0H-FH (ch. 1-ch. 16) * When this message is received, the following controllers will be set to their reset values.

However if Hold 1 or Sostenuto is ON, the sound will be continued until these are turned off. qOMNI OFF (Controller number 124) Status BnH 2nd byte 7CH 3rd byte 00H n = MIDI channel number : 0H-FH (ch. 1-ch. 16) * The instrument will behave in the same way as it does when an "All Notes Off" message is received. The mode will be OMNI OFF, POLY(Mode 3). When Identity Request is received, Identity Reply message will be transmitted. Even if the Device ID is 7FH(Broadcast), Identity Reply message will be transmitted. Since EH = 14 and 08H = 08, this is a Program Change message with MIDI CH = 15, program number 08 (Strings in HP-700). <Example 3> 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. B3 64 00 (B3) 65 01 (B3) 06 40 (B3) 26 00 (B3) 64 7F (B3) 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 qAbout tuning HP-700 is tuned by sending RPN #1 (Master Fine Tuning) to the appropriate MIDI Rx channel. 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. +----------------+----------------+----------------------------+ |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)| +----------------+----------------+----------------------------+ <Example> Set the tuning of HP-700 to A4 = 442. 0 Hz Send RPN#1 to basic channel. If the MIDI Tx/Rx channel is set to ch. 1, below is the message we transmit. B0 64 00 MIDI ch. 1, lower byte of RPN parameter number: 00H (B0) 65 01 (MIDI ch. 1) upper byte of RPN parameter number: 01H (B0) 06 45 (MIDI ch. 1) upper byte of parameter value: 45H (B0) 26 03 (MIDI ch. 1) lower byte of parameter value: 03H (B0) 64 7F (MIDI ch. 1) lower byte of RPN parameter number: 7FH (B0) 65 7F (MIDI ch. 1) upper byte of RPN parameter number: 7FH In other words, the above messages specify a value of 40 00H for RPN parameter number 00 01H (Master Fine Tuning) on MIDI channel 4, and then set the RPN parameter number to 7F 7FH (RPN null). [. . . ] 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. qExample 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. rHow 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. We will assume that in the exclusive message we are transmitting, the address is aa bb and the data or size is ccH. [. . . ]
