If I want to display a ramp (or any other parameter, I guess), but have it permanently disabled, I have to create another dummy parameter just so I can say

{ my_dummy_parm == 0 }

in the Disable when: box.

And then I have to make my dummy parameter Invisible.

It works, but it seems a bit silly - trouble is I can't find any thing I can stick in the Disable when: box that evaluates to true without referring to a real parameter on the left hand side. So this doesn't work:

{ 1 == 1 }

So - any way to disable a parm without having to create another parm?

(Why permanently disable a parameter, you ask? So I can do this: https://imgur.com/a/e80Ewzi [imgur.com] )

Sorry for not being of any help, just want to say nice idea!

Try using the isparm() function. For example, if the parameter's name is “feedback_ramp”, set Disable When to “{ isparm(feedback_ramp) == 1 }”.
