When you apply a midi learn in the mixer (on the fader from a rack), you cannot manage it in the rack itself. So, you can get 2 different midi messages, one from the mixer, and one from the output of the rack.
a bit messy... (2 hours on a patch to find what happened :/)

is it possible to fix it ?
thanx

You can midi-learn almost everything in Usine. The main drawback is that it can be quickly confusing.
I don't think there is some "fix" about it.
The next major release will have a learn list to display all affected controls.

Thanks Senso,
A list to display affected control will be enough. And it will show where are problems
