Yes, I understand what you mean, But If I have song In Multitrack, I will have Song 1 on Ch. 1+2 and the next song on 3 + 4 and so on. How can Auto change from 1+2 too 3+4. and I only use Foodshift. Play. I like to be on on Stage and only use Foodshift. I do not want to go back to Utrack and change Chanal. Thats why I make songs In multitrack / Stereo. And here is that problen with output level change. from song one to number 2 song.
