Is it possible to open MOGG files in Cubase Pro 9.5?
No.
.mogg files wont open but .ogg files work , you can open .mogg files by renaming the file name from .mogg to .ogg
your pc may give you a warning that the file might not work if you rename it just click on OK and its done , keep a duplicate of the original just to be sure tho … i just tried it on cubase 8 and it worked flawlessly
edit : make sure you tick on the split channels box when you import the file or it will only give you a single track with no audio
