Hi all!
I have this:

No matter what if the input increase or decrease also the output will increase or decrease; es. even if the input goes from 1000 to 999 the output will do0 to -1.
An that's fine. I would like to have on the output a slider that goes from 0-26 and that increase or decrease no matter what the value in input is. Es. the slider is set to 26; the input goes from 1000 to 999; the slider goes to 25.

Is that possible?

Like this?

Exactly what i was looking for!
Thanks a lot!

@nuromantix Actually I have a problem!
When I run it on pd on my Macbook it works just fine.
When I run it on the raspberry pi it goes out of scale! It doesn't stay on the 0-26 but it goes up and down without a limit.

I'm afraid I don't know about R-Pi. Presumably it is a slightly different version of PD.
You'll just have to add a bit of maths to limit the values I guess.

@Congarou The slider itself is setting the limit in @nuromantix example. Has the slider lost its range settings (bottom 0, top 26) on the rPi? I can see no other reason straight away. If that is not the case you could add [min] and [max] like this........
