This is something I've been wanting for a while: The ability to modify free envelope points using MIDI Learn instead of just the ADSR parameters.

This actually turned out to be pretty easy to implement, and I already have a prototype locally which works. Each axis of each point is independent, and you can learn both axes, or only one, it's up to you. I just haven't done the UI part yet, so my prototype depends on saving a MIDI Learn file and then making manual changes before loading it again.

But I do have some questions:


- Question 1: What is the meaning of the word "increment" when it comes to envelopes? This is mainly used by the CLI currently, but it will also show up in the MIDI Learn list. Typically it's referred to as "X increment", which in actuality refers to the Time taken for the curve to progress to that point. I don't see how the word "increment" is related though...

This is important, because currently MIDI Learn data is saved by string value, not index, so the name is set in stone once we pick it.


- Question 2: When Ctrl-Shift-clicking on a point, you will learn that specific point, obviously, but there are two axes you could learn. My suggestion for how to present this in the UI is simply:

1. Pops up "Learning Env Freemode Point 2 X (Time)"
2. It also contains the string "To learn the other axis, click Cancel".
3. If it is learned, it disappears and only that axis is learned.
4. If you click cancel, it pops up "Learning Env Freemode Point 2 Y (Amplitude)", and now it will learn that axis instead.

Does that sound reasonable?
