Hi Phillip, I agree with Stephan, your original code will create new instance of SinOsc and ADSR each time the while loop is processed.
I just want to warn you about the fact that the solution you implemented is not totally safe. When adding e=<dac, SinOsc and ADSR created just before are disconnected from the dac. So they will not use CPU anymore. That's why your problem seems to be solved. But SinOsc and ADSR are just disconnected. ChucK keeps them in memory. So if you plan to use your code for long time, you might run out of memory on your system. My advise is simply to move SinOsc s => ADSR e => dac; outside of the while loop.
