If you insert more than one, the sound will be louder.
Hi! Could it be you are using VST2 versions of Pro-Q 3 on a mono track in Cubase? There's a routing bug using the mono VST2 version in Cubase. Please use the VST 3 version instead.

When I insert multiple Q3s in one track, the sound becomes louder. What should I do?
