I reported a bug to Neural via their support email and it has been recognised and will be worked on.
The bug : When I assign an expression pedal to the input gain (input block) I can select the expression 1 or 2 and set the range. Once done and the assign screen closed, it will never show again when opening the assign window (although the assignment remains) on Cortex Control. I can’t either see in on the QCs.
This on both QC and QC mini (lates CoreOS and Cortex Control).
They have replicated the bug and reported it to the coding team.
Hope that helps
