I actually found it easier to sequence my 16 Ch AC lights in LOR as you only have the basic options AC will take (on/off, ramp, shimmer, twinkle) and IMHO they are easier to insert and less to think about.

Then thanks to some great tutorials by Keith, I've converted them to xLights where I've added my RGB pixel arches. Look for the Webinar series here:

Then when you get into pixels on xLights the possible effects are endless... Gil, Keith and the others do an amazing job writing and updating this program. For instance, the new poly-line feature could be very useful for people who have mapped a string in LOR's Visualizer that previously wasn't as easy to duplicate in Xlights.
