NOTES ABOUT THE MIDI IMPLEMENTATION CHART
The “MIDI Implementation Chart” on Page 34 illustrates the details of the key- board’s MIDI function. An O in the chart means that the keyboard has this fea- ture; an X means it does not have this feature. The following notes explain what the keyboard can do.
Basic Channel — MIDI uses up to 16 channels to exchange data. As in a TV broadcast, different channels send dif- ferent data. The keyboard can send data in any of 16 channels, but receives data only on channels 1 through 4 or 10.
Mode — The chart shows that Mode 3 is OMNI OFF, POLY. This means the key- board sends and receives polyphonic data on only one channel at a time.
Note Number — This number repre- sents each key of the keyboard. The lowest number (0) is five octaves below middle C. Since the keyboard’s lowest note is two octaves below middle C and the highest is three octaves above mid- dle C, your keyboard can send note numbers between 36 and 96 and re- ceive note numbers from 0 through 127. The keyboard automatically assigns any key outside its range to a key within its key range.
Velocity — This number shows how fast the key was pressed, or how loud the note should sound. Pianissimo (1) is the lowest velocity, Fortissimo (127) is
28
the loudest. A zero (0) means the key is released. Your keyboard can send and receive all volume levels from 0 through 127.
9n — This means that the Note On mes- sage is 9 hexadecimal, and n is the channel number.
Pitch Bender — The keyboard receives (but cannot send) pitch bending signals.
Control Change — This feature sends data on various controllers, each having its own number. For the details of each parameter, see “MIDI Data” on Page 26.
Program Change — This feature changes the preset sounds. Each sound number corresponds to a program num- ber between 0 and 127. For more infor- mation, see “MIDI Data” on Page 26.
