I don't see how the LEDs being arranged in a circle would make any difference in what the LEDs do, but I figured out that Circular does do something when the Width and Smoothness sliders are set to higher values. With Circular off, the pattern does not start over again until it has moved to the last LED and all LEDs turn off. With Circular on, the pattern starts again at LED 1 before the last iteration has completed. Now I am trying to figure out what Color Mode 2 does in the Laser preset.
I'm just playing around with the provided presets and wishing that Aquacomputer would invest the time to freshen their RGBpx platform. The Farbwerk360 is a wonderful RGB controller but IMHO the presets in Aquasuite are rather limited. In the past, Aquacomputer said they were going to add RGBpx port sync, and a new module called RGBpx Fusion, but sadly neither has happened. I also wish they would consider allowing more than 90 LEDs per port, which I think could be safely implemented by simply limiting the brightness when more than 90 LEDs are specified. Most RGB effects are not setting all LEDs to white at 100% brightness. My Farbwerk360 driving 5 x 15-LED strips at100% Brightness is only drawing about 250ma. If I extrapolate this for 360 LEDs doing the same thing, the total current draw would only be 1.2A. Clearly the Farbwerk360 could drive more than 90 LEDs per port while using typical lighting effects.
