Any way to detect overlay notes?

I downloaded a very nice score from Musescore in three formats as I normally do. I loaded it in Cubase and started assigning my own instruments, but I noticed something strange. When I got to the violins, I noticed that when I was playing the track and there were some longer notes, there was a rather strange sound to them that wasn’t the usual. And when I would play the same notes on my keyboard with that VSTi, they would play normally, but when playing the MIDI part, that weird noise came again, something that sounded as if it was out pf phase.

So it occurred to me that perhaps there were some notes that were duplicated, and to test this theory, I didn’t select with a rectangular marquee, but rather clicked on a note and pressed delete. When I did that, the note was still there, so what I had guessed was the problem actually was. There are a lot of duplicated notes, in all the tracks I tested that. Then I found some that are not, but those are the least.

If I select using the usual rectangular marquee and press delete, it deletes all the notes. The only way to delete just the duplicated notes would be to click on each one and press delete, which then shows the note below it. And by below I mean not in the Y axis, like another pitch, but in the Z axis, meaning the duplicated note takes up the same exact space as the other one, same pitch, same length, same velocity.

Obviously I did the usual troubleshooting, because the first thing I thought was that I had accidentally pressed a key that caused that. But I loaded the MIDI in Logic Pro X and it’s the same thing. I also redownloaded the files and it’s the same.

So I was wondering if Cubase has any way to select duplicated notes that are like these, sitting right on top of the same exact note, so it basically looks like one note, but when you press the spacebar and play that part, it sounds weird.

Yes there is!
MIDI > Functions > Delete Doubles

(I think this function has been there since the very first version of Cubase.)

Also it sounds like you might be trying to deal with this from within the Score Editor. Since the problem is really caused by the underlying MIDI Data, the Key Editor is a better choice in this case.

Also when you deleted the Note to tell if it was doubled, a nondestructive alternative is to move it up or down a couple of half-steps.

Man I love Cubase.

Oh I don’t know music enough to work directly on the score editor, the key editor is always my choice.

That would work for just a note or two, but if you have hundreds of them, and there’s no way to select just the notes on top, it would take too much time.

But well, Cubase as always is the king of MIDI and has an easy solution for that.

Well just for detecting the situation, not correcting it. For example in your case what if you deleted the Note and no other Note was found? Not a big deal, you just use undo, but moving leaves the Note intact even when there is no doubled Note.
