I'm wondering about autofocus functions in m4l?

Good morning all,

I am wondering if there is a way to have two instances of polygnome m4l running without seeing the lights of both instances on the grid, at the same time, when switching between the midi tracks?

Also what is the difference between the mono and the variable setting in autofocus?

The only thing that changes in polygnome when I have it set to variable is the repeat button light does not light up.
