Animate a parameter on the 2s with an expression?

Hi, I’d like to animate a parameter using an expression.

Specifically, I’d like to have the param animate on the 2s, in other words, advance every other frame.

Are drivers required for this or can expressions be used directly in parameter fields?

Thank you!

On the graph editor there’s a modifier that does this.

Hey, You can type expressions into the property fields as long as it starts with ‘#’, ex. = # frame / 8
