I have a shape layer that I want to parent it's vertical scale only (leaving the horizontal unaffected) to a Red Giant Sound Keys output.
The resulting affect would be the shape layers scaling up and down to the audio, while it's horizontal wasn't changed.
In the attached image you can see I have generated the Sound Key output keyframes. Unchecked the constrain proportions for the scale property and parented that to the Sound Keys output. I just need to know what I need to add to the existing expression to get the result I am after.

Any and all help is very appreciated.
