if you automate an on/off state of a fx device, it will be written to the pattern as commando (I would prefer a point in the automation graph!).
What’s highly missing is the automation delete menu on right click on the on/off button, just like all graphical automation provides.
If I automate a on/off state and later decide to remove this automation, I have to workaround by doubling the fx and then delete the old one. And then all parametric automation also is lost.
