Programming a Button to Increment/Decrement a MIDI CC value
It is possible to configure a button to increase or decrease a value each time it is pressed. This is useful if you want to step through values one by one each time a button is pressed.
To configure a button to increment a MIDI CC between a minimum and maximum value, assign the button to number 154 (see "Assignable MIDI CCs" on page 41). The minimum and maximum values are set using the Data 2 and Data 3 parameters respectively.
This requires four values to be specified (values given are examples):
|
| Key | Parameter | Value |
|
|
| ||
Control Assign | Increment MIDI CC | 154 | ||
|
|
|
| |
Data 1 | (example) | MIDI CC number | 72 (Release Time) | |
|
|
|
|
|
Data | 2 | (example) | Low Limit | 0 |
|
|
|
|
|
Data | 3 | (example) | High Limit | 127 |
|
|
|
|

The following example configures a button to increment the release time of the currently active MIDI instrument sound patch every time the button is pressed (you may have to push the button several times while playing notes to hear a difference).
1.Select the Control as described earlier in this guide (Button or Pedal).
2.Press the Advanced button.
3.Press the Control Assign key.
4.Enter 154 using the number keys. This sets the button or the pedal to increment the MIDI CC value.
5.Press the Enter key.
6.Press the Advanced button.
7.Press the Data 1 key.
8.Enter "72" using the number keys. This specifies the MIDI CC for which values will be incremented.
9.Press the Enter key.
10.Press the Advanced button.
11.Press the Data 2 key.
12.Enter 0 using the number keys. This specifies the minimum value.
13.Press the Enter key.
14.Press the Advanced button.
15.Press the Data 3 key.
16.Enter 127 using the number keys. This specifies the maximum value.
17.Press the Enter key.
To configure a button to decrement (decrease) a MIDI CC value, assign the button to number 153 (see Appendix B). The minimum and maximum value (range) for each button is set using the Data 2 and Data 3 parameters respectively.
NOTE: Each button will only increment or decrement its own parameter value and this value is independent of any other button. In other words, assigning one button to increment a parameter and another button to decrement the same parameter will cause the first button to send values such as 1, 2, 3, etc., each time the button is pressed. Pressing the second button will send values such as 127, 126, 125 (as opposed to starting to decrement where the first button left of; for example 2, 1, 0).
