Not really. As lorenzo said, PD has strict rules regarding inlets and order or execution. The [* ] only stores the value of the right inlet. Any value sent to the left inlet will not be stored, it will simply be multiplied by the stored value. So when you change the DeTuner value, it will simply be multiplied by itself. There are other ways to accomplish what you want, but I think the simplest is probably to use two [* ] objects. See attached.
