The following example will configure a button to "hard pan" the sound to the right speaker when it is pressed for the
first time, and "hard pan" to the left speaker when it is pressed for the second time. This involves configuring the
button to operate as a toggle, while controlling the Pan parameter (MIDI CC 10):
1. Press the Edit button.
2. Press the Select button or Control Select (Ctrl Sel) key.
3. Select a button as described earlier in this guide.
4. Press the Control Assign (Ctrl Asgn) key.
5. Type 146 using the number keys. This configures the button to operate as a toggle.
6. Press the Data 1 key.
7. Type 10 using the number keys. This specifies which parameter the button will toggle "on and off". In this
example, MIDI CC 10 (Pan).
8. Press the Data 2 key.
9. Type 0 using the number keys. This sets the second button press value to zero. In other words, sound will be
panned "hard left" when the button is pressed a second time.
10. Press the Data 3 key.
11. Type 127 using the number keys. This sets the first button press value to the maximum value, so that the sound
is panned "hard right" when the button is pressed the first time.
12. 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 the button the first time, and pressing the button
the second time.
Assigning MMC Control to Buttons
The transport functions of some hardware recording devices and DAW applications can be remotely operated via
MMC (MIDI Machine Control) commands. MMC is a specialized transport control protocol and requires a somewhat
different configuration method. The following values need to be specified:
Key
Control Assign
Channel Assign (example)
Data 2 (example)
Parameter
MMC control
Device ID
MMC function

Value
149
127
