Graphical Issue when Comping Lanes?

Cubase
,

Tried searching for this issue but didn’t come across anything. First off, here are specs:

  • Cubase Pro 10.0.20
  • 2018 MacBook Pro running Mojave 10.14.5
  • 2.9GHz Intel i9; 32gb 2400 MHz DDR4 RAM; Radeon Pro Vega 20 4 GB; Intel UHD Graphics 630 1536 MB
  • UR44 with up to date driver & firmware

Now for the issue: when creating a comp track from different lanes (different takes) a waveform appears at the crossfade even though there is no audio data present. Screenshot of “comped” take at crossfade point:

When I go down to the expanded lanes, I can see there is no audio data present at the point of the crossfade in either lane:

Now, if I Bounce and Replace the two audio segments, this “phantom” waveform disappears:

There is no audio or noise that plays when this waveform appears, but it is a bit unnerving and distracting when trying to make comps of takes. Anyone else notice this behavior? Thanks in advance for any help.

Hi,

Isn’t it a noise? Could you zoom the Waveform in?

Hi Martin:

Thanks for the reply! There does appear to be some amp noise present, but the waveform that appears doesn’t seem to fit with the amplitude or position of it.

Here’s a screen recording of the behavior: 20190805-CubaseFade on Vimeo

Quick followup as I noticed some other odd behavior with the disappearance of the waveform in question. It seems there is a certain point where the waveform from the resulting crossfade “flickers” and disappears: 20190805-CubaseFade2 on Vimeo

Hi,

Could you provide a sample project (with these 2 audio files), please?

Of course. Do you have a preferred way of uploading the project file?

Thanks again,
Don

Hi,

Link to Dropbox/Google Drive or similar would be great. Thanks.

Its a visual bug/glitch thats been present for quite a long time (at least since v7). It was confirmed but unfortunatelly never fixed. It randomly appears when editing crossfades.

thanks from me too!

Hi Martin:

Here’s a Dropbox link to the project. I put markers in a marker track where the graphical error appears. Dropbox - 20190728-SteinbergForum.zip - Simplify your life

Thanks again!

Thank you, Janko! It’s at least somewhat reassuring to know it’s not user error. I was starting to doubt my crossfading abilities for a minute. Still a shame that this has persisted throughout so many versions
