[sdiy] Generating a large number of CV outputs

[cheater cheater]

brian said you have to record the output at over 44.1 to see it,
meaning it's above fs/2, meaning it can only be imaging due to a bad
reconstruction. aliasing from algorithms is below fs/2. case closed.

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.
