I was looking around a lot for help on eventing custom sliders, rotating knobs, and switches. There were some things available for C2 but not C3. I took inspiration from a couple of C2 files offered up here years ago (credit is given in the c3p). Code has been customized to work for instancing copies of the elements that will continue to work independently. Changing instance variable inputs allow for a great deal of flexibility. I hope you find this useful as an example or starting point. All assets are my own and are free for you to use as you please (no restrictions).
