When changing a MSEG segment to a nonlinear shape with small slope at the beginning and large slope towards the end point, the resulting curve looks pretty uneven. If I had to guess I'd say it probably follows some kind of power law, not the typical smooth exponential curve you would expect. It's also not symmetrical to the shape you get with large slope at the beginning an slow slope at the end point.
I do realize that, strictly speaking, fixing this would break backwards compatibility. OTOH, I cannot imagine the current behavior to be useful in musical terms so I reckon it's seldomly used in practice. All that said, it's certainly not a dealbreaker.

Re: DUNE 2: weird MSEG shapeYes power law is correct. MSEGs are multiple segment envelopes - they work somewhat different from typical ADSR envelopes, since they allow jumps, modulating rate, looping etc. I doubt there's two ways to implement MSEGs, but if you've seen something else we can always take a look.
Soundwise it doesn't make much of a difference ihmo, as the curve shapes you can get are rather similar compared to the classic exponential ADSR envelopes (if that's what you want). Changing the curve shape is definitely useful for sound design though, there's quite many factory patches doing just that. Admin - Synapse Audio Software

Re: DUNE 2: weird MSEG shapeWould this make increasing vs decreasing curves different? I've noticed that dragging the curves up or down to their max results in asymmetrical shapes on either side of a point. It seems like they should be symmetrical about the point. Here is two images of what I'm talking about..
