3.4 Levels
Levels can be set using either absolute values or in relative 1dB
increments/decrements.
MSB and LSB are a parameter number showing where the signal is being sent
from and where it is being sent to.
 MSB/LSB parameter numbers are shown in the reference tables.
An absolute level is represented with a combination of course and fine values.

Where: N= MIDI Channel, MB/LB = MSB/LSB Parameter number, VC/VF = Value
