Channel Group Switching
The [Matrix Mixer - Crosspoint] editor window displays four channels each for Input and Output.
It displays the channel group that was clicked on in the matrix mixer component editor. The
[Channel] buttons in the [Input] and [Output] sections of the [Matrix Mixer - Crosspoint] editor
window switch the channel group that is displayed.
If you click another channel group when the matrix mixer component editor is active and an [Matrix
Mixer - Crosspoint] editor window is displayed, that channel group will be displayed in the open
[Matrix Mixer - Crosspoint] editor window.
Only one [Matrix Mixer - Crosspoint] matrix window is displayed for each matrix mixer component
editor.
