This happened multiple times on a machine with cubase 9 elements 9.0.40, windows 10 professional…
Since this occures unexpected I cannot give an procedure to reproduce the bug.
While preview playing samples in the mediabay right zone and groove agent se 4, I encountered that samples were pitched down an octave or play slower for no reason, I did not alter tempo or anything.
And it stays like this. You cant undo it.
So if you preview playing the samples again in the media bay browser it will not be resetted to normal speed.
I did never press “align beats to project”
