Waveform Color Filling
Hello, I am working on an audio template. I am trying to make a waveform similar to the one you can see in Soundcloud. I’ve managed to program an expression to generate the waveform. But I am having an issue with filling up the waveform with a color with respect to time. For example, do you see on soundcloud how the waveform fills up orange as the song progresses? This is the concept I am trying to work on. Here is what I have so far:
This is a continuation of a project that a user on here by the name of Kevin Camp (if you’re still active on this forum) helped someone out about a year ago. Here is a link to the original post with the process I used: https://forums.creativecow.net/thread/227/27263
I want the blue bar to move to the right over time, but I only want the white parts of the waveform to turn blue as it progresses (the rest of the blue solid hidden). How would I go about doing this? My knowledge in After Effects is limited so any help is GREATLY appreciated! Thank you

Use the Waveform you generate as a Track Matte for the blue solid, combined with an animated mask that reveals the color as the music progresses.

That’s what I was thinking, but I was using this expression code featured here: https://forums.creativecow.net/thread/227/27263
I have to duplicate each solid (to generate the waveform seen in the picture) about 100 times.
Is there a way to disable the expression code but keep its parameters so that I could duplicate it and add it as a layer above it? Does that make sense?Basically, I don’t have just one solid waveform, I have a whole bunch of duplicates to generate the whole waveform therefore I cannot do a track matte :/

You can do a track matte if you precomp all of the layers together and use the resulting composition as the track matte.
