GLITCH ON THE TAIL OF THE SAMPLE (please, help!!!!)

Hallo everybody, i discover a random glitch added by Cubase on the tail of my kick sample.
please, listen to the link to understand what I’m saying: https://soundcloud.com/matteo-gabbianelli/kick-clip/s-K9i4UWCh44U

I first duplicated the kick and added a fadeout on every event. I still heard the glitch, but it’s not in the sample itself, therefore i thought there was an issue in Cubase’s fadeouts and i put the sample in Groove Agent to loop it, but the random glitch is still there. I also tried to change Elastique Pro’s algorythm, freeze the track, increase the buffer, turn off asio guard, delay compensation and whatever…nothing worked… What’s the problem???

The production chain is:
prism sound ada 8xr
avid hd native
mac pro 2013 - 3,5 GHZ 6-Core INtel Xeon E5 - 16 GB DDR3 ECC 1866 MHz
OSX El Capitan

Thank you for your attention and (i hope) for helping me.
Matteo
