No Audio Readout On MIDI Channels?

Question for Artist Series Controller Users. As usual. I tried the Artist Series Forum FIRST and go no response. So, I’m expanding my search for an answer.

Why is there no LED activity on the Artist Series (MC Control or Mix) Hardware for MIDI Track Sample playback? Audio shows LED activity and MIDI channels feeding my synth rack (Which is, again, audio coming into the Nuendo) but there is never any info coming from the MIDI tracks triggering the samples. You can see plenty of activity on the DAW faders, but nothing on the corresponding hardware meters. :confused:

So what’s different about MIDI playback? :question:

I finally got a response from Avid. They said to ask Steinberg. :unamused: :frowning: Can anyone here, offer a HELPFUL answer?
