Yamaha CS6R Data List - Page 26

About MIDI MIDI is an acronym that stands for Musical Instrument Digital Interface, which allows electronic musical instruments to "communicate" with each other, by sending and receiving compatible Note, Control Change, Program Change and various other types of MIDI data, or messages. The CS6X/CS6R can control a MIDI device by transmitting note related data and various types of controller data. The CS6x/CS6R can be controlled by the incoming MIDI messages which automatically select MIDI channels, voices and effects, change parameter values, and of course play the voices specified for the various Parts in a Performance. MIDI Messages Transmitted/Received by the CS6x/CS6R The MIDI messages can be divided into two groups: the Channel Messages and System Messages. Below is a brief explanation of the various types of MIDI messages which the CS6x/CS6R can receive/transmit. CHANNEL MESSAGES The Channel Messages are the data related to the performance on the keyboard for the specific channel. •Note On/Note Off (Key On/Key Off) Messages which are generated when the keyboard is played. Each message includes a specific note number which corresponds to the key which is pressed, plus a velocity value based on how hard the key is struck. •Control Change Control Change messages let you select a voice bank (Bank Select), control volume, panning, modulation, portamento time, brightness and various other controller parameters, through specific Control Change numbers which correspond to each of the various parameters. •Program Change Messages which voice to select for each Part. With a combination of Bank Select, you can select not only basic voice numbers, but also variation voice bank numbers. •Channel Aftertouch Messages which let you control the sounds by the pressure you apply to the keys after the initial striking of the keys, over the entire channel. •Polyphonic Key Pressure Messages which let you control the sounds by the pressure you apply to the keys after the initial striking of the keys, for each individual key. The internal sequencer (CS6x/CS6R) can send this message. •Pitch Bend Pitch Bend messages are continuous controller messages that allow the pitch of designated notes to be raised or lowered by a specified amount over a specified duration. SYSTEM MESSAGES The System Messages are the data related to the overall system of the device. •Exclusive Messages Exclusive messages control various functions of the CS6x/CS6R, including bulk dump, master volume and master tuning, effect type and various other parameters. •Realtime Messages Messages which control the sequencer including Start, Stop, Continue, MIDI clock and Active Sensing messages. •Common Messages Messages which also control the sequencer including Song Select and Song Position Pointer messages. MIDI Data Format Many MIDI messages listed in the MIDI Data Format section are expressed in hexadecimal or binary numbers. Hexadecimal numbers may include the letter "H" as a suffix. The letter "n" indicates a certain whole number. The chart below lists the corresponding decimal number for each hexadecimal/binary number. Decimal 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 Hexadecimal 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F Binary 0000 0000 0000 0001 0000 0010 0000 0011 0000 0100 0000 0101 0000 0110 0000 0111 0000 1000 0000 1001 0000 1010 0000 1011 0000 1100 0000 1101 0000 1110 0000 1111 0001 0000 0001 0001 0001 0010 0001 0011 0001 0100 0001 0101 0001 0110 0001 0111 0001 1000 0001 1001 0001 1010 0001 1011 0001 1100 0001 1101 0001 1110 0001 1111 0010 0000 0010 0001 0010 0010 0010 0011 0010 0100 0010 0101 0010 0110 0010 0111 0010 1000 0010 1001 0010 1010 0010 1011 0010 1100 0010 1101 0010 1110 0010 1111 0011 0000 0011 0001 0011 0010 0011 0011 0011 0100 0011 0101 0011 0110 0011 0111 0011 1000 0011 1001 0011 1010 0011 1011 0011 1100 0011 1101 0011 1110 0011 1111 Decimal 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 Hexadecimal 40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 5B 5C 5D 5E 5F 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 7B 7C 7D 7E 7F Binary 0100 0000 0100 0001 0100 0010 0100 0011 0100 0100 0100 0101 0100 0110 0100 0111 0100 1000 0100 1001 0100 1010 0100 1011 0100 1100 0100 1101 0100 1110 0100 1111 0101 0000 0101 0001 0101 0010 0101 0011 0101 0100 0101 0101 0101 0110 0101 0111 0101 1000 0101 1001 0101 1010 0101 1011 0101 1100 0101 1101 0101 1110 0101 1111 0110 0000 0110 0001 0110 0010 0110 0011 0110 0100 0110 0101 0110 0110 0110 0111 0110 1000 0110 1001 0110 1010 0110 1011 0110 1100 0110 1101 0110 1110 0110 1111 0111 0000 0111 0001 0111 0010 0111 0011 0111 0100 0111 0101 0111 0110 0111 0111 0111 1000 0111 1001 0111 1010 0111 1011 0111 1100 0111 1101 0111 1110 0111 1111 Additional Notes • For example, 144 - 159(Decimal)/9nH/1001 0000 - 1001 1111(Binary) indicate the note-on messages for the channels 1 through 16 respectively. 176 - 191/BnH/1011 0000 - 1011 1111 indicate the control change messages for the channels 1 through 16 respectively. 192 207/CnH/1100 0000 - 1100 1111 indicate the program change messages for the channels 1 through 16 respectively. 240/F0H/1111 0000 is positioned at the beginning of data to indicate a system exclusive message. 247/F7H/1111 0111 is positioned at the end of the system exclusive message. • aaH(Hexadecimal)/0aaaaaaa(Binary) indicates the data addresses.
