disagree. a lot of synth modules end up being some form of ring
modulator when presented with HF control inputs. that of course ends
up in the audio range after the ring modulator mixes it with the audio
inputs.

Granted, you have to record higher than 44.1 kHz to see this, since most DAC hardware is running at least that sample rate or higher.
