Thank you for the examples. I did the same tests with the MultiPanner of Nuendo and I was able to get the same results.
And yeah my first impression is that Nuendo did not really have a Lc. But since they have now the JUCE mapping makes totally sense.
It is just hard to adapt our plugin with the Nuendo since we do not support that layout.
Thank so much for replying. Best regards,
