I have an effect rack and want to automate the macro know with a Midi controller 20. I don't have an midi controller devices so have set up Midi Loopback and have a midi clip with a few values of CC20 in. I set that playing in session view and in my audio bus where I am trying to use the automation select the macro know and armed Midi Map Mode.

The mapping is showing as I would expect now

However, when I play the session scene the macro just runs up from 0 to 127 irrespective of the CC20 value it is receiving
Any ideas appreciated
