Sidechain with Wavelab 12?

How to actually use the signals here for sidechain?

I am looking for a frequency split (dynamically controlled by an envelope), than use those splits individually and put them together in the end.
Is this possible with Wavelab 12? If so, how?

Hi!

Have tried with plugin in a Montage?

regards S-EH

WaveLab 12 does not support side-chaining.

Ok, this is a clear statement.
This means, that the plugin has an unusable feature?

Will it be in Wavelab 13?
If not, why?

This seems to be the wish for many for years by now.
