Cheers Stuart you’ve been brilliant. Problem sorted!

While looking into what you said about fill I figured out I that you could gradient fill as well so I changed that on the shape layer and then added keyframes to change the colour manually. Then the opacity is changed based on volume information contained in the audio track (well the null object version of this any way…).

Thanks a lot, you’ve helped tremendously
Best of luck

I’m sorry but I’m a total beginner with AE (only 2 days now but have mostly what I want to do working)

At the moment I’m extracting the auido volume data and assigning it to a circle. At the moment I create this circle by making a new solid layer and masking it with the ellipse tool. I then feather this a bit to make it look nice.

I need to be able to write into a time line of sorts, what colour a circle will be at a given point in time and be able to change this. I dont mind manually writing this so after effects won’t have to work out pitch, just what colout to change to and when…

I’m not too sure about what you mean by using the fill, I notice there are a number of ways to do things which result differently so you may have to be sepcific (esp given my limited knowlage on AE).

An example I noticed was creating a circle could just be done with the ellipse tool with a fill but unless I do it on a solid layer I cant feather it. I’m assuming it having to do with one being a shape layer and another being a solid with a mask. Either way I just need to figure this last bit about how to automate colour change and I’m home free.

Again cheers for the help

Actually, I was saying I was already using the convert audio to key frames command but then I ran into a problem then linking it.

I slowly figured it out from web tutorials. But still have a few problems on the next stage…

I linked the opacity of the circle to the volume and then used the expression: linear(value,8,25,0,100) to re map the opacity levels. This works fine for transperency though I now have to figure out how to change the circles colour on different notes.

Basically the velocity is now linked with opacity of the circle. I need to be able to change the circle (probably manually) when another pitch is sounded. Is there any way to write in the fill colour of the circle and change it over time?

I plan to have several circles of different colours doing this but with each coloured circle representing a different pitch of the chord, I’m not sure if that will limit my options…

Cheers for the help lads, I appreciate it greatly
