I know in X1 there IS a multilane NUDGE bug, if you have more than one lane of midi recorded then lassoed notes from anywhere BUT the top lane, then attempted to nudge to the right or left (9,6,3/7,4,1) the lassoed notes would all jump to the layer or track above. Very annoying when trying to nudge your grooves and they disappear. Actually set to not show muted layers and the Nudge Bug will nudge them Up into a muted clip instead of Over appearing to disappear. Maybe X2 has carried this Bug over. Also, your focus should be on the PRV, and not on the Track view as the track view nudge nudges up and down tracks not just the notes. As of now I'm NOT upgrading to X2. I'm testing out Cubase, Studio One, and maybe DP8 for PC when it comes out.
