Hi,
Thank you for the reply.
I understand what you mean about the mute button in the instrument track header (to the right of the solo button) muting the audio that the track is passing to the output.
What's confusing me is specifically the MIDI mute button in the instrument section of the track header, to the right of the MIDI input device drop-down menu. Clicking on that mute button doesn't mute the MIDI flowing from the input device to the RTAS instrument on the track. So, if I understand correctly what you're saying, that MIDI mute button is not working as intended -- at least on my PC, in my test session.
But, as I say, maybe I am overlooking something obvious...
