Custom curve for sensor3

Hi there!

we’re having some difficulties creating a custom curve on net3 concert so we can use simultaneously our sensor3 and some old robert juliat dimmers. 

any advice on the best practice to draw a curve?

is it possible to use a square curve to start drawing a new custom curve?

Anyone with same experiences?

the custom curve editor is not very accurate, specially when there is the need to meticulously edit values beteween 0 and 10%…

thanks in advance,
