Hi,
I’m sorry, English is not my first language either.
OK, you are talking about the Instrument Tracks and its multi-outputs.
If you set the “snare fill in” as an Audio Return Channel (output) of the Instrument track, then once you select the Instrument track itself, the Channel part shows this Audio Return Channel (output).
If you would select the Output 1 (Main Out), you would see this one in the Channel.
