Trigger layer with sound
on Feb 13, 2018 at 11:25:54 am

Hi,

I have a face with 10 different expressions, every expression is another layer. I also have a beat made only of hi-hats. With every high-hat I want the expression to change, either randomly or sequentially. Any idea how I can do this?

There are probably several ways to do it.

One would be to lay down markers on every beat (easy to do by doing an audio preview [by pressing . on your number pad] and then hitting the * key on your number pad to lay down markers.
Apply an expression that messes with time remapping based on the index of the layer.
Then, just split the layer on every marker (probably a script for that).
Bam. A new frame for every layer.

You can also trigger layer animations by layer markers with expressions. I wonder if there's an easy way to iterate a value...

Hi Michael,

Not to sound incompetent, but would you happen to be aware the expressions in question? :)
