[maxmsp] stutter~ based patch popping on bang?

The following patch is bugging me: whenever I click the bang to grab some of the incoming sound, it sends an audible pop to the dac~. I thought stutter~ would only send output on receiving an appropriate trigger in the middle or right inlets. Why am I hearing a pop?
