My ultimate intention is to shape tween different object based on different frequency outputs from a song. IE High notes shape tween objects A, low notes shape tween objects B...and so on. (I am no blender genius) At the moment, I have started with beating hearts.
I managed to get sinusoidal shape tweening using the top 6x nodes seen in the image. However, relating to the bottom set of nodes, I can't work out how to: a) extract useful sound values (comparing with online tutorials it seems I can't access some of the sound related nodes) b) translate them into a useful value to input into shape tween
