@H.H.-Alejandro Sorry, it's just my mistake...... as I was building and testing at the same time.
You can change it to what you want...... so the reverb_width to 6Z would be "correct" but nothing is correct because it can be what you want.
If you want to use curve 7 you will need to move evry parameter to the curve below....... 8 to 7, 9 to 8 etc.
There are 39 curves available, each with Y and Z....... but I have not completed enough effects to use them all.
You don't have to use Y and Z if you don't want to.
I put "local" in case you want to "fix" a parameter...... and not have it controlled by a curve. Trying to cover every possibility.
David.
