I’m not sure if this is an issue or not, but my workflow includes having a vocal track included in each song. Normally, I would like to just send this output to the “nc” output so as to not hear it. It appears that there are three different ways to achieve this: 1st: in the track header clicking on the “send” icon
Which gives me:
from which I can then select the “nc” . Second: selecting the highlighted “send” icon:

which brings up a dialog where I can select “nc” from the top of the dialog:

And finally clicking on the “Audio Outputs” selector:

and the “nc” under Audio Outputs.
I’m not sure which one of these methods I’ve used (I’ve assumed they are interchangeable) . BUT: the “nc” is not always saved and sometimes the track that I DON’T want to hear comes out.
I can’t be sure how to reproduce it, but I’d like to suggest that you check all three methods to ensure that this disconnected output stream is saved with each method. BTW - I have not tested this with 1.3.12 yet.
One more thing: it would be really handy to have an indicator of the current output routing somewhere on the track header so I know where the output is directed. Even if the current output were highlighted in one of the dialog boxes, this would help as currently there is simply no way of knowing where the selected track is routed.
Thanks
