I’m afraid my question wasn’t clear enough… so I’ll try with an example.
The VST Instruments Rack has a VSTi loaded which has, say, 32 stereo outputs (64 channels). All of them are enabled.
There are 32 MIDI tracks sending to that VSTi and the audio signal can be found in the corresponding audio output of the instrument (MIDI track 1 to “Output 1-2”, MIDI track 2 to “Output 3-4” etc).
Now suppose you rename both MIDI tracks and output channels (in the Mixer or in the Project Window, under the VST Instruments folder). Imagine MIDI track 1 called “Bass” and Output 1-2 called “Bass” as well.
Now you shuffle the tracks order around for whatever reason (imagine you want to group several tracks closer together in the Mixer), keeping the output tracks in the same order as the MIDI tracks so as to keep everything tidy.
Now, if you look at whatever output track you want in the VST Instrument folder in the Project Windows, there is no apparent way to see what’s the original output channel’s name (“Output 1-2” in the above example).
You can find that out by looking at the MIDI track’s inspector pane, see what MIDI channel it sends on, go to the VSTi plugin window, see what audio output this channel is sitting on, and deduce from that. But isn’t there a quicker way to do that?
