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.
