I've been trying to bake sound to f-curves in the graph editor for a plane (on the x-axis.) Every time I do this it makes the plane "bounce" in both directions. I understood what was happening and tried to add a delta scale key to selected vertices so that it would only "bounce" the vertices. When I tried to add the key it just popped up with an error message saying, "no suitable context info for active keying set". I really need help with this. Thank you.
