Controller 32 is the Least Significant Byte (LSB) associated with 
Controller 0. As far as I know, most devices don't use the LSB 
because the MSB allows selection of up to 128 banks.

The VL70 has an unusual implementation of bank select, since it has 
only twelve banks. It appears that Yamaha is allowing for multiple 
categories of banks, in order to accommodate various General MIDI 
formats such as XG. In order to select among the VL70's four main 
banks, the MSB (Controller 0) is set to 33 and the LSB (Controller 
32) is set to 0, 1, 2, or 3. In order to select among the VL-XG banks 
(banks 112-119) the MSB is set to either 97 or 81 and the LSB is set 
to the corresponding bank number 112-119.

Has anyone encountered similar implementations?
