I spent a good 4 hours today on programming a song for this year's display. It's John Lennon's So This is Christmas.
I was able to get the north poles done. The red rope light between the north poles is done only when the jingle bells hit all 4 beats in the middle of the song. The roof stripes mirror the north poles. Now that I did the base beat for the roof stripes and north poles, I can go back next time and tweak.
The biggest pain is that I can analyze the beats per minute (BPM) with a program, but the BPM changes throughout the song. So, it's almost faster (and definitely more precise) if I just manually click for every beat.
