4. PROGRAM CHANGE Data format: [CnH] -> [ppH] CnH = Program event (n = channel number) ppH = Program change number P.C.#=Program Change number YDP-151/YDP-323 Grand Piano 1 Grand Piano 2 E.Piano 1 E.Piano 2 Harpsichord 1 Harpsichord 2 Vibraphone Church Organ 1 Church Organ 2 Strings MSB 0 0 0 0 0 0 0 0 0 0 LSB 122 112 122 122 122 123 122 123 122 122 P.C.# 1 1 6 5 7 7 12 20 20 49 • When program change reception is turned OFF, no program change data is transmitted or received. • When you specify a program change as a number in the range of 0-127, specify a number that is one less than the program change number listed above. For example, to specify program change number 1, you would specify program change 0. 5. Pitch Bend Change [EnH] -> [ccH] -> [ddH] ccH = LSB ddH = MSB 6. SYSTEM REALTIME MESSAGES [rrH] F8H: Timing clock FAH: Start FCH: Stop FEH: Active sensing Data F8H FAH FCH FEH Transmission Transmitted every 96 clocks Song start Song stop Transmitted every 200 milliseconds Reception Received as 96-clock tempo timing when MIDI clock is set to External. Song start Not received when the MIDI clock is set to Internal. Song stop Not received when the MIDI clock is set to Internal. If a signal is not received via MIDI for more than 400 milliseconds, the same processing will take place for All Sound Off, All Notes Off and Reset All Controllers as when those signals are received. • If an error occurs during MIDI reception, the Damper, Sostenuto, and Soft effects for all channels are turned off and an All Note Off occurs. 7. SYSTEM EXCLUSIVE MESSAGES (Universal System Exclusive) (1) Universal Realtime Message Data format: [F0H] -> [7FH] -> [XnH] -> [04H] -> [01H] -> [llH] -> [mmH] -> [F7H] MIDI Master Volume • Simultaneously changes the volume of all channels. • When a MIDI master volume message is received, the volume only has affect on the MIDI receive channel, not the panel master volume. F0H = Exclusive status 7FH = Universal Realtime 7FH = ID of target device 04H = Sub-ID #1=Device Control Message 01H = Sub-ID #2=Master Volume llH = Volume LSB mmH = Volume MSB F7H = End of Exclusive or F0H = Exclusive status 7FH = Universal Realtime XnH = When n is received n=0~F, whichever is received. X = don't care 04H = Sub-ID #1=Device Control Message 01H = Sub-ID #2=Master Volume llH = Volume LSB mmH = Volume MSB F7H = End of Exclusive (2) Universal Non-Realtime Message (GM On) General MIDI Mode On Data format: [F0H] -> [7EH] -> [XnH] -> [09H] -> [01H] -> [F7H] F0H = Exclusive status 7EH = Universal Non-Realtime 7FH = ID of target device 09H = Sub-ID #1=General MIDI Message 01H = Sub-ID #2=General MIDI On F7H = End of Exclusive or F0H = Exclusive status 7EH = Universal Non-Realtime XnH = When received, n=0~F. X = don't care 09H = Sub-ID #1=General MIDI Message 01H = Sub-ID #2=General MIDI On F7H = End of Exclusive When the General MIDI mode ON message is received, the MIDI system will be reset to its default settings. This message requires approximately 50ms to execute, so sufficient time should be allowed before the next message is sent. 147 YDP-151/YDP-323 Appendix/Anhang/Annexe/Apéndice 41
