Glith/creak issue in musical mode

Hi there,

When I read a sample in musical mode, I have some glith/creak issue if I put my locator at the very begining of the clip. No problem with the same sample with musical mode off.
I tried to increase my buffer size (Focusrite Scarlett 8i6 3rd gen) but it doesn’t change anything.

I have no problem with the VST instruments latency and my Cubase projects run smoothly moreover.
Any idea ? Maybe it’s normal to have this very short noise in musical mode if my locator is too close to the audio clip ?
