Expanded Value Sequences (FR)

I think it would be powerful and intuitive if the value sequences could be expanded to cover curves and the time domain. In theory it could allow for comprehensive transformations without a need for a fancy GUI for the curves. I'm just spitballing syntax, but what if you used ( ) to define the section of the curve that the following values are in, and [ ] to define time variables until the next [ ].

So a value sequence of:

(0-0.33), 1, 2, 3, (0.33-66), [0.3], 7-11, (0.66-1), [1], 6-4

Would go between values 1, 2, 3 within the first third of the curve as normal. The second third of the curve would go between 7 and 11, but take .3 seconds for the value to "catch up" to the position of the source. The final third of the curve would decrease the value from 6 to 4 with a full second of catch up time.

Now I'm straying into deep water here, but what if you could synchronize the time parameter to the BPM? You could make a button that slowly raises a filter over 3.75 bars and then quickly drops it back down with:

[BPM3.75], 2000, [BPM.25], 0

Or with some curves:

[BPM3.75], (0-0.46875), 0-1500, (0.46875-0.9375), 1500-2000, [BPM.25], (0.9375-0.9675), 200, (0.9675-1), 0

For smoothing a track peak, maybe just a value sequence of [.2] would work, in that it takes .2 seconds to catch up to the current value from the last value.

I have no idea if this is possible or if there are complications I'm not considering but if something like this would work I think it would cover all possible control transformations we could want.
