As a rookie, I'd strongly suggest you use the xLights controller functions unless you have a very particular need that it just doesn't work for you.
The main advantage is that you don't really have to configure specific universes and channels because xLights is a smart universe/channel bot. The main enablement of xLights smarts is the visualizer button that allows you to put your props on your controller. xLights will figure out all the universes/channels and when you upload your config, it will be correct for how the visualizer was set up. Try it out. I think you will like it.
