I'm hearing a tone before pressing button object, why?

No way would I want to ask this forum another question like this if I hadn't tried to fix this problem for almost an hour+ now. :D It could be that I don't understand partial~ as that's a totally new object for me. But I'm less than 3 weeks on *all* objects so who knows. :p

My issue is, when I press the ezdac~ I am getting a sinewave tone before I press the the button to make the 2 operator synth sound. This synth if from the tutorials, I didn't want to just copy and paste it, so I took a screenshot and added the objects myself, in order to get a better understanding. But maybe there is some code that I'm missing or god forbid a patch cord missing or in the wrong place that's doing this.

Here's a small screen video that explains it much better.
