Seems to have been updated since the bad reviews.
I just downloaded version 3.1.2 of this app. I was terrified by all the bad reviews, however, they now have the names above the tracks and also have pictures of an instrument. The stereo panning is variable not just left, right and center. It is only landscape, but the controls do not seem small to me. They seem similar to other iPhone mixing apps. I have not used it live and cannot review live functionality, but I just wanted to update what is on this version of the app. One thing that I don’t like, is when I reach down to the bottom of the screen to lift a fader that is all the way down, the app sometimes thinks I am swiping up to shut the app down and then shuts the app down. I found a workaround is just to place my finger a 1/2” or so above the bottom of the screen when I start to scroll up on the fader that is all the way down. The fader still goes up with my finger.
