Harmor has buzzy noise (lees then other synths yet) when slide notes or automation clips changes velocity. Its will be easy to avoid noise at all, if apply volume and pan to the oscillators at the moment when signal passes zero point. I use such approach in my own synth, and result is very smooth. It is does not require any additional CPU usage and let to avoid any additional smoothing processing, like volume level interpolation between ticks:
I`d be happy to see such improvement in Harmor.
