Setting Trigger Values for the Buttons or the Sustain Pedal

It is possible to set a Trigger Value for a button or the sustain pedal, causing it to send one value when pressed and held down, and another value when released.

The sustain pedal is already configured to send trigger values by default, ensuring it activates the sustain effect when pressed and deactivates it when the pedal is released. Buttons can also be configured to operate this way, which

requires four values to be specified. At the example of the sustain pedal, these four values are:

		Key	Parameter	Value
Control Assign			Trigger On/Off operation	146
Data 1		(example)	MIDI CC number	64 (Sustain)
Data	2	(example)	Button/Pedal Released	0 (minimum)
Data	3	(example)	Button/Pedal Pressed	127 (maximum)

NOTE: When working with proprietary M-Audio parameters from the 128-255 range, the "Control Assign" setting is used to configure a button or the sustain pedal for this special mode of operation. This means that certain values that are usually specified through the "Control Assign" setting must instead be specified via the "Data 1" parameter (such as the standard MIDI CC parameter in the example below).

The following example will configure a button to "hard pan" the sound to the right speaker when it is held down, and "hard pan" to the left speaker when it is released. This involves configuring the button to operate as a trigger, while controlling the Pan parameter (MIDI CC 10):

1.Select a button as described earlier in this guide

2.Press the Advanced button

3.Press the Control Assign key

4.Type 146 using the number keys. This configures the button to operate as a trigger (press/release). See Appendix B

5.Press the Enter key

6.Press the Advanced button

7.Press the Data 1 key

8.Type 10 using the number keys. This specifies which parameter the button will trigger and release. In this example, MIDI CC 10 (Pan). See Appendix A

9.Press the Enter key

10.Press the Advanced button

11.Press the Data 2 key

12.Type 0 using the number keys. This sets the "release" value to zero. In other words, sound will be panned "hard left" when the button is released.

13.Press the Enter key

14.Press the Advanced button

15.Press the Data 3 key

16.Type 127 using the number keys. This sets the "press" value to the maximum value, so that the sound is panned hard right when the button is pressed.

17.Press the Enter key

TIP: It can be useful to transmit two other specific values instead of sending minimum (zero) and maximum (127) values as in the above example. When assigning a button to control Pan (MIDI CC 10), you can, for example, configure Data 2 to send value 38, and Data 3 to send value 93, effectively causing pan to switch between the approximate "ten o’clock" and "two o’clock" positions when pressing and releasing the button.
