Pro Q3 Cubase volume issue
Could it be you are using the VST2 version of Pro-Q 3 on a mono track in Cubase? There is an issue with the audio routing with the mono VST2 version, where the input is going straight to the output parallel to the signal passing through the EQ. So every EQ move you make is parallel. Solo'ing a band will only solo the signal going through the EQ, but the other signal will be audible as well.
We've reported this issue to Steinberg many times, but since they will abandon VST2 soon I'm afraid they will not fix it. Please use the VST3 version instead, which works as it should. You can recognize the VST3 version by the /// symbol next to its name. Also the VST3 version is simply called "Pro-Q 3", where the VST2 version is called "FabFilter Pro-Q 3".
Ralph, thank you very much, Meanwhile I figured out, that there are two versions of plugin with different names, and yes it's exactly as you described. Issue solved.
Hello.
Strange behaviour of Pro Q3 in Cubase 12 (Macbook Pro M1). Inserting plugin immediately changes the volume of the signal. Volume knob on the plugin is not working. Anyone experiecing the same issue ?
