Sample not looping smoothly over a bar.

I have the same problem here in the transition from one sequence to another (in song mode) with the sample in the audio track. Even when I convert a song to a sequence, the loop get´s cut very slightly but very audible. When I loop the sequence itself it loops perfectly.

Edit: Not a sample loop problem, the gap appears in song mode even when I solo the drums, between one sequence to another. Ridiculous. When I convert the song to a sequence, the drum track transition are smooth, but the audio track goes gap.

I was using JJOSxl 1.37. Upgraded to 1.46 and nothing change.
