So I've tried this two ways, I've put the plugin on the insert and also on the master (mastering page) and I get the same result.
I set the output to -3.2 in the plugin
It only peaks at 6.5 according to the plugin
BUT when I click the "update the loudness" it show 2.7,,,
If I increase the gain on the plugin, the TP in Studio One is off the charts.
Shouldn't it be showing me the TP after the plugin?
Is there a setting I'm missing

Hi Michael,

I think there must be some confusion about the metering in Pro-L 2. Could you send me a short video that illustrates your issue? Please send it to info@fabfilter.com

Thank you in advance!
