FabFilter

In Pro L you can alt drag the gain slider to do the inverse gain change on the output, except this does not work in pro tools because the alt key resets the gain slider. Is there any way to use this functionality in pro tools?

Is this solved yet?

This still seems to be broken with build 1.21 and Pro Tools 12. I never knew about this feature but the bug seems to be related to the same issue I had with Pro-Q 2 and Pro Tools 12.

With Pro-Q 2, holding option locks the frequency in place but allows you to change the gain and Q but something in Pro Tools 12 broke that and the frequency would reset (I believe to 1k) when you tried to option click on the node.

Hopefully FabFilter can put this on the list for the next round of updates.

Because Pro Tools is Pro Tools, they do it with their own pre defined key commands. Shift is the method the inversely lock the input and output together in Pro L. Obviously that's for a windows machine, itd be the same for whatever button is equivalent on a mac.
