Hello!

I work in Ableton Live 10.1.9 - Mac Osx 10.13.6.
When I use the VST2 version of Pro L2, and turn on the dithering, i can see the background noise on the Ableton meter (it is usually around -70dbfs)
When I use the VST3 version, there is no background noise ... it is completely silent ........
I also tried on Reaper and this thing doesn't happen ....... in both versions (VST2 and VST3), I can see the background noise on the meter .......

Do you think it's normal?

Thank you!

This happens when the input is silent. The VST3 plug-in detects this condition and also returns silence as a CPU-saving measure. All VST3 plug-ins do this. Once you do a test with a non-silent input, you will get the dithering noise (but it is of course harder to measure this way).

Cheers,

Thank You!
