Program Change

Program Changes are used to change the instrument or voice you are using. For the sake of example, we will change the instrument to a bass sound. To do this we need to send a program change of 32, which will select an acoustic bass sound from the General MIDI Instruments list in the Appendix of the user guide.

Note: If you are not controlling a General MIDI instrument, please refer to your software or sound module's documentation for a list of sounds and the corresponding program and bank change values.

There are two ways to send a program change:

1. Incremental/Decremental Program Change:

  • Press the Advanced Functions button.
  • Press the black key above F1 (named F# 1).
  • Now the Octave “+” and “-” keys can be used to change the program.
  • Press “+” and continue to play notes until you find the instrument you want.


2. Quick Select Program Change:

  • Press the Advanced Functions button.
  • Press the black key above F4 (named F# 4), representing “Program.”
  • Press keys C4, then E3 then C5. This enters the combination: “3,” “2,”“ENTER.”  Alternatively, you can use the “+” and “-” buttons to change the value, then press ENTER. Now the keyboard will play a bass sound: Number 32 as listed in the General MIDI Instruments list.


The first method is useful if you want to cycle through different instruments to see which sounds best in your song. The second is more useful if you want to select a specific number, as is the case here.

If the Octave “+” and “-” keys are selected to vary the Program number (Method 1), the lights above the buttons will not change, since it is not possible to have a Program with a negative value. Pressing both the “+” and “-” buttons together will recall Program 0, which selects a grand piano sound.

The full list of General MIDI instruments that can be accessed via Program Changes is listed in the Appendix at the end of the keyboard's user guide. 

 

Bank LSB and Bank MSB

Program Changes are most commonly used to change instruments and voices. However, the number of instruments accessible via Program Changes is limited to 128. Some devices have more than 128 voices and require a different method to access these extra voices. Generally, these devices use Bank LSB and Bank MSB messages.  Please refer to your software or sound module's documentation for a list of sounds and the corresponding program and bank change values.

1. Incremental/Decremental Bank LSB and Bank MSB Changes:

  • Press the Advanced Functions button.
  • Press the black key above G1 (named G# 1).
  • Now the Octave “+” and “-” keys can be used to change the program.
  • Press “+” and continue to play notes until you find the instrument you want.


2. Using the Quick Select Method:

  • Press the Advanced Functions button.
  • Press the black key above G4 (named G# 4), or A4 (named A# 4), representing Bank LSB or Bank MSB respectively.
  • Press keys C4, then E3 then C5. This enters the combination: “3,” “2,” “ENTER.”  Alternatively, you can use the “+” and “-” buttons to change the value, and then press “ENTER.”


As with Program Change, if the Octave “+” and “-” keys 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.
