Thank you. I use a Light O Rama 16 channel. You have to buy the starter package because it include the cat5 to USB link to your computer as well as the light sequencing program. You can buy more boxes and daisy chain them together and essentially run an unnumbered amount of boxes.
The tree uses 8 channels to run it. This means with one box, you can run the tree and then back up singers. (the back up singers will be running together on 8 channels).
The 8 channels for the tree are divided up as such : outline of body, closed eyes (lower eye), open eyes (upper eyes), upper lip, middle lip, lower lip, o mouth, and closed (or square) mouth. I used 100 led light strand for the body, and the other parts I used 50 led light strands. (All from Walmart.)
The sequencing for light show or the talking faces is rather complicated and time consuming. Fortunately, there are a lot of amazing people over at Liht o Rama forums that can help with that. They already have hundreds of light show and sequenced faces available for free. You may have to pay for the songs on some sequences (they don’t always give them to you because of copyright laws). The songs usually only cost a dollar. They will even take requests to build the sequence for you, but you need to do it early in the year.
Once you get the sequences and music set up, connect up your tree to the light o rama, and connect the box to a computer. I use a fm transmitter that transmits the music to the spectator’s car. Click to run the show and you are live.
Here are the links of the things you need to buy and the sites for free sequences. There are sales throughout the year the prices drop by a hundred dollars.

… This is sold out from the company I used, check back or copy the model number and do a search for other companies.
I hope this answers a lot of questions for you.
