Hello David and thank you for your return,
Even selecting a parameter from the menu does not work.
I can automate in READ mode or if I assign the button to a macro, but not in Latch, Touch or Write mode.
A line appears, with a second dot where I start moving the parameter, but no automation is recorded. Just a straight line.
This works very well for my other plugins though, so I'm sure I'm doing the right thing.
