I tried watching the video but for some reason wouldn't play on my phone. I'm doing a LOR halloween show this year for the first time. I have ran a christmas one for the last 4 years. The sequencing does take a very long time, but some places do actually sell the singing face programs for a couple dollars already done for those that don't have the patience. My halloween show is 5 controllers, a few less then 80 channels used and you'd be surprised how quickly it can go up. Generally programming is the most time consuming part, and usually your props are prebuilt so it's just a matter of putting them up and plugging them in.
My first show goes live this Saturday night, have had neighbors waiting outside the house a couple nights this week lol
