I thought you could still freeze a track even though another track's compressor
was side chained to it, in version 10.
I don't know what happened with that, because I'm getting those same old version9
prompts: "you can't freeze this track because of that other track's compressor".
There are 4 tracks side chained to this track, and even turning the compressor OFF
doesn't allow for freezing. So....yeah...
Even in older versions, you could still Export the track's audio while side chained.
