I just upgraded to sonar professional and I can't get snap to work on the piano roll. I have tried adjusting the snap settings from light to extreme and everything else I could think of and nothing works. I used to do most of my work in sonar 2. I upgraded to 7 but never really used it, but I remember snap didn't work for me in that either. Now i'm using professional and this is driving me nuts. 

seems working as it should

Thank you, I'm used to using such a old version everything seems new. I was changing the wrong snap setting. I didn't notice the tiny one on the piano roll.
