FPP turn single pixel on during show

Hi All,

Did everyone make Dec 1 to have their show up and running?, I had most except the matrix running last night.

I have a QR code poster for remote falcon and want to use a pixel flood to light it, I have read I should be able to turn this channel on from FPP when the playlist starts.

What the best (Easiest) way to do this? background sequence or script?

Thanks
Anthony

also interested was considering the same thing and undecided if i use pixels or something dumb
