I'm trying to understand the different routing logics present in Ableton Live.
My goal is to route a Drum audio track to the side-chain external input of a compressor vst, whom effects a MIDI track where sits a VST Instrument.
The problem is the "Audio To" dropdown from the Drum track doesn't show my MIDI Track (and, specifically, its linked Compressor-VST channel).
I also tried to pass the Drum track through a Return channel and send it to the VST Instrument channel but it presents the same lack of choice in the "Audio To" selection list (it just shows the Audio channels and the default choices).
Anyone knows why? Probably I'm missing a point about the rules for sending tracks in Ableton.
