Bank LSB and Bank MSB
Program changes are the most commonly used messages to change instruments and voices. However, the number of
instrumentsaccessibleusingonlytheprogramchangeMIDIcommandislimitedto128.Sincesomedeviceshavemorethan
128 voices, they require a method to organize their large number of sounds into banks. These devices then access the sounds
withinthesebanksbyusingprogramchangemessages.Seechapter“MIDIMessagesExplained”foradditionalinformation.
Generally, these devices use Bank LSB (Least Significant Byte) and Bank MSB (Most Significant Byte) change messages.
KeyRig49cansendthesebankchangemessagesintwopossibleways*:
1) Incremental/Decremental Bank LSB and Bank MSB Change:
1. PresstheEditModebutton.
2. PresstheblackkeyaboveG1(G#1)orBb1(A#1),representingBankLSBorBankMSBrespectively.Nowthe
Octave“<”and“>”buttonscanbeusedtochangeBankLSBorBankMSB.
2) Using the Quick Select Method:
1. PresstheEditModebutton.
2. PresstheblackkeyaboveG4(G#4),orBb4(A#4),representingBankLSBorBankMSBrespectively.
3. Pressthewhitekeysassociatedwiththebanknumberyouwishtoselect,andthenpressC5(Enter).Forexample,
pressingtheC4(thenumber3),A3(thenumber1),andC5(Enter)keysinthisstepselectsbank31.
AswithProgramchanges,iftheOctave“<”and“>”buttonsareselectedtovarytheBankLSBorMSBnumber(Method1),
the lights above the buttons will not change, since it is not possible to have a Bank with a negative value. Pressing both the
“<”and“>”buttonstogetherwillrecallBank0.
Bank change messages must be followed by a program change message in order to recall a sound. Bank change message by
themselves do not activate a sound, but only locate and access a predefined location of a set (bank) of 128 sounds.
PLEASE NOTE: Each time the keyboard is turned off, optional MIDI parameters assigned to the
Octave buttons will be lost. When the keyboard is powered up, the Octave buttons will default to
controlling octave shift.
