Hello,
I need to increase the volume of a track controlled by the volume of another track. I know how to decrease it - via a sidechain compressor, but I have no idea to do the opposite. In a nutshell: Any idea of how to simulate the behaviour of a VCA within the Sonar Mixer?
Thanks in advance...

Side chain the Sonitus gate. Set the gate depth at about -3 dB below FS for starters.
When the gate opens the audio will be full unity gain and when the gate is closed the audio will be at -3 below unity, or where ever the depth is set.
 Adjust attack, hold, and release for best sound.
 

I just tried it. It works perfectly! Sometimes the "old" plug-ins do the magic... Thanks
