Wire Properties in Track View


I’m trying to see how something was achieved in wire parameters. In the attached image we have different actions for an object. They are controlled by Custom Attributes within a dummy block. We have ‘Pitch’ for example, is a Wire Float that is a copy of ‘Pitch Animation’ (Bezier Float) which is where the keys are added and modified, and any changes are replicated to the ‘Pitch’ wire. I have tried to replicate it unsuccessfully. If anyone has an idea of how it was created I would greatly appreciate the help. The person that created it before me no longer works for the company.

Thanks for the help,
