Thanks Keith,
Right now I plan to have one set of these models with Falcon and another with San Devices using FPP to play everything. Haven't used Falcon's virtual strings so something to look at and not familiar with FPP's features to model pixels within a model.
To clarify, I have multiple models (same configuration) with each having 3 rectangle pixels (RBG), single pixel node (RGB), and 3 rectangle pixels(RBG) on single strand of lights. Not sure if that makes any difference in the response.
