When loaded, CueMix succesfully controls volume, trim and all other parameters. Than loaded MainStage. Select the new template, Audio Input as MOTU, output as MOTU. If I put the audio on Inputs 1-2, I see the signal. Than I am going to Layout and created couple faders and couple signal meters. In Edit , I map faders with Input 1 and 2 volumes and signal meters with Input 1 and 2 signal meters. I see the signal, but when I moving faders in MainStage, nothing happens. In CueMix, it's works.
Apparently, this is my mistake in setting assignments, and I will appretiate any assistance which can lead me towards working configuration.
