A-1. Decimal VS Hexadecimal
With a MIDI System, the data value, the address, or size in an exclusive message is
expressed in 7-bit hexadesimal values.The table below shows decimal value and thier
hexadecimal counterparts.
When expressing a MIDI channel number or 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.
