It's more that Bezier curves are questionably useful for audio parameter automation.

If you're automating level and panning you need assorted log/lin/exp curves, not Beziers. You also need to be able to see the waveform you're automating, which is something Bezie fails to offer.

Parameters automation works better with standard ease in/out curves and keyframing. Beziers are a special case of a more general problem.

This looks very nice, but I'm not sure how useful it's going to be to most users in practice.
