Shortcuts “Y then I” not work

In Wavelab 9.5.50 if I press the shortcuts “Y then I”, I can trigger the start of the “Level meter” audiometers. In version 10.0.20 this does not work.

You mean, to meter the audio input? In WaveLab 10 you need to have the Record Dialog to be opened for this feature to be possible.
Another possibility, it to click on the Master Section “Microphone” icon at the top left of the Master Section, to monitor the audio input.

Indeed if we open the registration window beforehand it works.
Thank you !
