MSB & LSB PARAMETERS
Some controls need more than 128 values available in a stand MIDI CC message. Luckily for us the
MIDI stand allows parameters to be split into 2 CC messages, called MSB and LSB.
Most significant byte (MSB) and least significant byte (LSB) might sound
scary, but they really aren’t.
All you must do is take the value you want and split it into two parts with a little bit of math.
•
Take your VALUE you want, divide it by 128.
•
The integer value (the number before the decimal point) is your MSB.
•
Now multiply the fractional part (the number after the decimal point) by 128 to get the LSB.
For example, if you want to set TIME L to 2000ms: (Time L uses CC3 for MSB & CC35 for LSB control)
•
2000 / 128 = 15.625
MSB = 15
•
0.625 * 128 = 80
LSB = 80
MIDI messages to send:
•
CC 3
15 (MSB)
•
CC 35
80 (LSB)
