LED lights
I need to make a visual representation of LED lights going up a and down to a piece of music,
I know I can use Trapcodes soundkeys to do this, but I can’t think how to go about this, Do I need to make the lights as masks, and then make a gradient from greed to red in a comp, then add the lights as masks and then some how from the output keyframes of the soundkeys plugin, add those to the gradient comp so that the gadient goes up and down behind the the masks of the LED lights, or does anybody know a better way of doing this effect. -

You’ve pretty much hit the nail on the head. I’d use the data from Soundkeys to control the vertical scale of a rectangle shaped matte layer. Make sure the anchor point of the matte is at the bottom & feather the top edge so you don’t see any hard edges as it rises and falls. Use this matte over your gradient. Then put your LED mask on top of everything and set it to Stencil Alpha. If you’re not familiar with Soundkeys try creating a similar matte using the Audio Spectrum effect (in Effects/Generate).
