Question Synchronizing lights to music

[teabreak]

Hi folks. Please could someone tell me how to sync a light with music, so that it flashes on/off in time to the beat.

Also, Is there a plugin available that can help with movement of atoms with music?

I think this is what you're looking, rythm forces
