I still prefer volume knobs versus software sliders and the M-Track’s large master volume knob is perfect – easy to grab and turn in small increments, right where I want it

My one issue is the one large knob which only controls audio output to the main outs

The four large knobs are nice and smooth

The great big knob (GBK?) is great - I LOVE it

and I love the big volume knob, which is a nice point of control if you don't mind it being top mounted.

Only 3 stars because the clip indicator only has 4 lights; -20dB, -6dB, -3dB and CLIP for 0dB peaks, the gain knob needs to be turned nearly all the way up for vocals and the big beautiful knob in the center seems to actually do nothing

However, I do appreciate the big convenient knob at the center.
