Hello

> The sound is almost never an issue because it is so quiet, but I was just wondering if there was a step I was missing in the process of silencing the VCO. But it sounds like this is just the normal functioning of the synth so I'll work around it. Thanks again for your suggestions!

I do not own a DE, but there will be some breaking through for sure. So
Andy is right to my opinion. The single synth voice chip used in the DE
was never intended to be used without any VCO signal. So there was no
need for the developper of the chip to provide a perfect 1000% signal
rejection.
