M-Audio 49i Quick Select Program Change, Bank LSB and Bank MSB, Using the Quick Select Method

KeyStudio 49i User Guide 26

B)Quick Select Program Change

1.Press the Edit Mode button.

2.Press the black key above F4 (F#4), representing “Program.”

3.Press keys D4, then B3, then C5. This enters the combination: “4,” “2,” “ENTER.”

Now the keyboard is set to play the GM Module cello sound 42 (from the General MIDI Instruments standard list). The full list of General MIDI program numbers is given in Appendix A at the end of this manual.

Method A is useful if you want to cycle through different instruments for the purpose of comparing and choosing which sound works best in your song. Method B is more useful if you want to select a specific sound patch, as is the case here.

If the Octave “<” and “>” buttons have been assigned to control the program number (Method A), 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 the first sound patch on any synthesizer capable of processing MIDI program changes.

5. and 6. 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 (0-127). 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 11, “MIDI Messages Explained” for additional information. Generally, these devices use Bank LSB (Least Significant Byte) and Bank MSB (Most Significant Byte) change messages. KeyStudio can send these bank change messages in two possible ways*:

A)Incremental/Decremental Bank LSB and Bank MSB Change:

1.Press the Edit Mode button.

2.Press the black key above G1 (G#1) or A1 (A#1), representing Bank LSB or Bank MSB respectively.

Now the Octave “<” and “>” buttons can be used to change Bank LSB or Bank MSB.

B)Using the Quick Select Method:

1.Press the Edit Mode button.

2.Press the black key above G4 (G#4), or A4 (A#4), representing Bank LSB or Bank MSB respectively.

3.Press keys C4, then B3 then C5. This enters the combination: “3,” “2,” “ENTER.”

As with Program changes, if the Octave “<” and “>” buttons are selected to vary the Bank LSB or MSB number (Method A), 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.

*Note: Bank change messages must be followed by a program change message in order to recall a sound. Bank change messages by themselves do not activate a sound, but only locate and access a predefined location of a set (bank) of 128 sounds.

7. Tuning

This key will assign the Octave buttons to increment or decrement the Master Tune Setting of the KeyStation 49i. The tuning range is +/- 50 cents. When the Octave buttons are set to control Master Tune, each button press is 1 cent. This only affects the internal sound engine. To assign the Octave buttons to affect the tuning of the built-in piano sound:

1.Press the Edit Mode button.

2.Press the black key above D2 (D#2), representing “Data = Tuning.”

Now the Octave “<” and “>” buttons can be used to adjust the built-in piano sound’s mastering tuning.
