The iD button can be used as a hardware function key. By default ScrollControl is set as the function of the iD button, however by right clicking on the iD icon in the master section of the iD mixer, you see a drop down menu where you can set what you want the button to do.
The iD button can be set to control:
- ScrollControl
- Mono
- Mono + Polarity
- Dim
- Talkback
