MSB and LSB
Fair Warning, this gets a little bit complicated, we tried to translate this into something humans
can understand.
MSB (Most Significant Bit) and LSB (Least Significant Bit) commands allow for a
greater variety of commands to be sent while still using a value set that is limited
from 0-127 (All MIDI messages — except Pitch Bend [PB] — have 128 possible
values associated with them). Think of MSB and LSB as an extension to the limit
of having 128 values for a MIDI message. There are 128 (0-127) LSB commands
for each of 128 (0-127) MSB commands. That means you have a total of 16,384
banks just from the MSB and LSB.
MSB and LSB commands are usually a sequence of 3 MIDI messages. Two CC
commands which have both the CC message itself and the value associated, and
a PC command which actually makes the change on the MIDI receiver.
The MSB Bank command is activated and set using CC:0 and the same goes for
the LSB Bank command which uses CC:32,
this is a standard for MIDI devices.
If you use the Singular Sound BeatBuddy, you will find it needs a PC command to
use CC:0 and C:32. Read more about how the BeatBuddy behaves using MSB and
LSB on
pg. 18.
The value of the CC command (CC:0 or CC:32) decides which specific layer of the
MSB and LSB banks is being activated. In terms of hierarchy, MSB comes before
LSB and LSB is before the Program Change message. The Program change adds
an additional 128 values to each of the MSB and LSB message configurations,
that means a total of 2,097,152 values.
The math may seem confusing. A good way of summarizing it is by noticing that
we have 128 MSB values, which are combined with 128 LSB values, and then with
an additional 128 PC values. The relationship is multiplicative, so we have a total
of 128 x 128 x 128 possible values. Similar to binary math (we know, super fun!)
you must organize the numbers in this order: MSB > LSB > PC.
This means you must select the MSB bank before the LSB bank, and the LSB bank
before the PC command for it to work correctly.
