• What are ‘Bank MSB’ and ‘Bank LSB’ messages ? The bank number is calculated using the following formula :

bank number = LSB + 256*MSB

• What this means is that a change in value of 1 in the MSB jumps the bank number by 256.
• Very often, only the LSB is relevant, as the instrument might not support more than 256 banks ( i.e. the MSB value is always 0 ).
