What you seem to be doing is creating a spectrum which has magnitude 1 everywhere, and the phase is varying at a constant rate vs frequency. That means it has a constant group delay.
So... my guess is that you'd get an impulse in each block, whose timing depends on the rate of the phasor. When you vary the phasor frequency, it will coincide with the peak of the hann window at some point and be its loudest.
Should be a periodic complex tone. I don't understand your goal: you've got sinusoids in the patch... to generate sinusoids?
