: 00H,00H - 7FH,7FH (bank1 - bank16384)
Default Value = 00 00H (bank.1)
* Ignored when “Rx.BANK SELECT = OFF.”
“Rx.BANK SELECT” is set to OFF by “Turn General MIDI System On,” and
set to ON by “GS RESET.” (Power-on default value is ON.)
* The LSB 7-bits are ignored (always regards as llH=00H) in this Model.
However, when sending Bank Select messages, you have to send both the
MSB (mm) and LSB (ll) together.
* “Bank select” is suspended until receiving “Program change.” To select a
Tone of another bank, you have to send a Bank select (mm,ll) before send-
ing the Program change.
* The “Variation number” of GS Format is defined as the decimal expression
of the MSB value (Control change number 00H) of the Bank select.

Portamento is ON or when using portamento control messages.
Value 0 is the fastest.

Use Expression messages for expression pedal, or creating expressive
effects, such as crescendo, decrescendo, while playing.
* Ignored when “Rx.EXPRESSION = OFF.”
