Music & LED Project Help

Thanks in advance for your help and ideas!

I have an art installation with up to 100 short strips of 2812b LEDs, which will be wired together in essentially one long series. I want to program them with my Uno to flash in various patterns. However, I have about an hour of music that I'm going to play - I want to cue the lights to do specific things at specific parts of the music. I don't want the lights to simply change in reaction to the music. I want to run the music from a PC, and cue specific LED changes every few seconds or so based on beats within the music track.

Any ideas?

Thanks.

How many LEDs?
You would send 3 bytes/LED to the long strip from the PC to the Arduino any time you wanted an LED to change, for the Arduino to then pass along. You have to send all the data to all the LEDs, even if just one changes.

Here is one way Christmas light shows are done. Probably overkill for your requirements but some useful ideas on how the pros do this.

Try searching for "computer controlled lights music" for more info.
