If you are expecting to see hitpoints and everything is set correctly, you need to click on the file/select it? Sorry if I misunderstood what you are getting at.
Actually (at least, with Cubase 12), when ticking the Enable Automatic Hitpoint Detection option and recording an audio event, the hitpoints appear as almost invisible vertical dotted lines. Although I see that nothing is visible on your arrange view screenshot, I suggest you to double click on the event to open the Sample Editor : the hitpoints should be there, clearly visible.
If not, as a workaround, try to open the sample editor : in its left panel, use the Edit Hitpoints command in the Hitpoints section. When closing the sample editor, in all case, the hitpoints should be visible, even in the arrange view but, at least on my end, ONLY when the event is selected…
Yep, in a sample such as yours, Cubase have issues, detecting them. Try to play, at least on the threshold setting, as it doesn’t seem that you have an Intensity one…
Failing that, ultimately the samples are to be loaded onto a Nord Electro 6. I am wondering if what I’m looking for can be achieved on the Nord Sample Editor s/w? In the past, I have always performed edits within Cubase and then exported them, though.
