Here is what we have in Studio One


As you can see, we have everything we might want.
For people who don't know, we can have S curve as well.
Select the middle point of any Line and hold [Alt/Option] to change it to an S curve.
But I think a random curve, or basically, a Sample and Hold curve will seal the deal completly.
Here is some pictures of S&H curves as Automation Drawing curves.


This S&H curve will be very good and very helpful I believe.
