Open questions:

How to shorten x_a now :/

Edit:

Now that I think about it, I remember how I constructed the model. Having the values run towards (1,1) is just a way to make sure the model looks pretty on desmos. But in reality, the script anyways calculates until (1, 1) has been passed (and then enters into next phase, which is decay) or stops prematurely because the player has lifted their finger from the key.

So indeed, the sigmoid function above should be implementable. Ideally with a nice draggable button. Maybe we can provide rails for the user to drag the button. Was thinking of something along the lines of: https://www.desmos.com/calculator/wwggmfktmw

I stepped back from this idea. Question is: Can such a curve as outlined in

be built using SVGs? Or is there a rewrite of the ADSR graph necessary?
