Technical question for Steinberg regarding pan law and VST3 sidechain input

I’m digging deep into some Cubase behavior, and have a couple questions:

  1. Is the pan law setting of -3dB (or 6) really 3 or rather 3.01? (Or 6.02)
  2. Does the pan law setting influence in any way the sidechain input for those plugins that receive it?
  3. It seems to me that the sidechain signal that get sent to plugins which support it, gets lowered about 3dB. Why is this happening? I have tested only a few at the moment, and I was wondering if this is dependent on Cubase or 3rd party plugin developer.

Thanks for your help!

  1. It’s not 3.00 nor 3.01, it’s log 2, that is close to 0.301029995663981… but an irrational number goes forever.

  2. If your side chain source is mono and the side chain input of the plug-in is stereo (usually is), the level is affected by the fx send pan. If the side chain signal is taken from the output or direct routing, the channel planner is involved.

  3. I assume the plug-ins you have tried has stereo side chain input and the source is mono, as above.
