* When expressing a MIDI channel number oder a program change number, please notice
that the values are less by one .For example, MIDI channel is expressed as 0 through 15
instead of 1 through 16.
* The range of 7 bit can express 128 steps from 0 to 127. To express broader range, use
several data bytes.
