Please ensure you're using the correct analysis method for your music. If the song has an absolutely consistent tempo (eg. from an electronic percussion), you should be using NORMAL analysis mode. If the song has a varying tempo (eg. from a live drummer), you should use DYNAMIC analysis mode.
Yes, sometimes the analysis can start at the wrong spot, but if you correct the 1.1 point, the remainder of the grid should be accurate.
If you have two tracks in sync, creating an automatic loop will keep the loop in sync regardless of the MT setting.
