While researching that, I realised, that the valueToText does not work in FinalCutProX:
In the Juce_AU_wrapper.mm this is never called in FCPX, but it is in Logic, if you open the automation graph:
FCPX uses the generic UI (called HUD-heads up display). But there only 0.0 … 1.0 with two digits are displayed. With the mouse it is probably impossible to move the slider finer anyway…
I added breakpoints in the valueToString, and they are never hit.
Is somebody around, who can have a look into that?
