Ah. ok.
"Receiveing audio (sidechaining your audio)
To receive audio from the virtual channels Alpha, Beta, Gamma and/or Delta, do the following:
Open a SideKickV3 on the (stereo)channel you want to sidechain and select the virtual channels (Alpha, Beta, Gamma and/or Delta) under 'use virtual channel' to use the audio on those virtual channels as sidechain input.
Note: This plugin needs to be loaded twice into 2 seperate channels in your VST host to be able to work. Because the plugins can 'see' eachother and use each others audio input. "
