The detail between
the control points.
A fast envelope can change between control updates. Explore a sample-by-sample signal alongside a slower, held control signal—and see what the update interval changes.

Illustration, not a product benchmark. The control trace uses zero-order hold with no interpolation. Real tools vary in update rate, smoothing, latency, and internal DSP.
