SYSTEM EXCLUSIVE MESSAGES (XG Standard) (1) XG Native Parameter Change Data format: [F0H] -> [43H] -> [1nH] -> [4CH] -> [hhH] -> [mmH] -> [llH] -> [ddH] -> [F7H] F0H = Exclusive status 43H = YAMAHA ID 1nH = When received, n=0-F. When transmitted, n=0. 4CH = Model ID of XG hhH = Address High mmH = Address Mid llH = Address Low ddH = Data | F7H = End of Exclusive Data size must match parameter size (2 or 4 bytes). When the XG System On message is received, the MIDI system will be reset to its default settings. The message requires approximately 50ms to execute, so sufficient time should be allowed before the next message is sent. (2) XG Native Bulk Data (reception only) Data format: [F0H] -> [43H] -> [0nH] -> [4CH] -> [aaH] -> [bbH] -> [hhH] -> [mmH] -> [llH] ->[ddH] ->...-> [ccH] -> [F7H] F0H = Exclusive status 43H = YAMAHA ID 0nH = When received, n=0-F. When transmitted, n=0. 4CH = Model ID of XG aaH = ByteCount bbH = ByteCount hhH = Address High mmH = Address Mid llH = Address Low ddH = Data | | | | ccH = Check sum F7H = End of Exclusive • Receipt of the XG SYSTEM ON message causes reinitialization of relevant parameters and Control Change values. Allow sufficient time for processing to execute (about 50 msec) before sending the instrument another message. • XG Native Parameter Change message may contain two or four bytes of parameter data (depending on the parameter size). • For information about the Address and Byte Count values, refer to Table 1 below. Note that the table's Total Size value gives the size of a bulk block. Only the top address of the block (00H, 00H, 00H) is valid as a bulk data address. 9. SYSTEM EXCLUSIVE MESSAGES (Digital Piano MIDI Format) Data format: [F0H] -> [43H] -> [73H] -> [xxH] -> [nnH] -> [F7H] F0H = Exclusive status 43H = Yamaha ID 73H = Digital Piano ID 01H = Product ID (digital piano common) xxH = Substatus nn control 02H Internal MIDI clock 03H External MIDI clock F7H = End of Exclusive 10. SYSTEM EXCLUSIVE MESSAGES (Others) Data format: [F0H] -> [43H] -> [1nH] -> [27H] -> [30H] -> [00H] -> [00H] -> [mmH] -> [llH] -> [ccH] -> [F7H] Master Tuning (XG and last message priority) simultaneously changes the pitch of all channels. F0H = Exclusive Status 43H = Yamaha ID 1nH = When received, n=0-F. When transmitted, n=0. 27H = 30H = Sub ID 00H = 00H = mmH = Master Tune MSB llH = Master Tune LSB ccH = irrelevant (under 7FH) F7H = End of Exclusive 6 P-105 MIDI Reference / MIDI-Referenz / Référence MIDI / Referencia MIDI
