MD+ uses CD sector values as loop points (you can see at 21 seconds I have the selection box changed to display 'Absolute Frames' to input the loop value of 4115). In the second half of the video I demonstrate how the loop should sound and how it is triggered. You can hear the loop triggered in G+GX at around 7 or 8 seconds, it goes back to the beginning. Here's a small video demonstrating a looped track in Xeno Crisis: If the track does loop, the loop point isn't accurate. Some tracks that are assigned to loop in the CUE file don't loop and some tracks that are assigned to not loop, will loop. There are some issues with loops with the recent MD+ addition.
