Just gave it a try with the Cubase 7.5 demo with the exact same results.
I would call this an important issue that should be fixed.
Free warp is excellent but the realtime algorithms do create artifacts. The flattening should help this artifact problem but is useless to me in its current state where it moves the position of the audio. (see the original pictures I uploaded.) Flattening the audio track also changes the sound of the snare drum. Brings out a weird low mid sound that is not heard before flattening.
How do I bring this to the attention of Steinberg?
Have you a) tried the same test with a “bounce” instead of a “flatten”, and then done the same two things on a brand new project (preferably a Steinberg template, just to be sure there’s nothing hidden inside)?
Thought I should be a little more detailed regarding the creation of my audio file.
I first recorded the snare hits using midi and Superior Drummer 2. Next I quantized the snare hits to quarter notes 100 %. I then created an audio file from the midi. So far so good.
Things go to pieces as described earlier.
Alexis, I will give your suggestions a try. (Have you a) tried the same test with a “bounce” instead of a “flatten”, and then done the same two things on a brand new project (preferably a Steinberg template, just to be sure there’s nothing hidden inside)?)
I have tried a few more things and you can see the results in the attached pictures.
Picture 1 shows the following:
first track is unedited quantized snare hits
second track shows that I have moved the last snare hit using free warp
third track shows what happened when I bounced the free warped track
fourth track shows what happened when I exported the free warped track
fifth track shows the result of flattening the free warped track
I must say that I am not impressed with the results. I hope that Steinberg can make it a priority to fix this issue. I just find it so much easier to edit something like a vocal track using the free warp method.
At least, on the bright side, bouncing and exporting works properly when the track was edited manually. (cut and moved a section of the audio) as can be seen in Picture 2.
Apologies for posting here, I went to comment in the thread linked to by the moderator instead of this duplicated one, but the linked-to thread is locked.
If I understand your tracks in pic 1 correctly, the 3rd one is a bounce of the edited one. It doesn’t look like the same waveform for the edited beat or the unedited beat, surprisingly to me. I’ve never looked at bounced waveforms at that high zoom level before …
Some questions for anyone who might know:
Is this fixed in 7.5.30?
Is this timing error audible only on rapid onset signals like snares, or also on piano, voice, guitar?
Any work-arounds that allow Free-Warp to be while keeping the timing intact?
I’m confused here, as I didn’t see this issue in the Cubase 8 Collected Issues list? It does appear in the Cubase 7 list, but as there are no more versions of Cubase 7 forthcoming, it’s destined to always stay there, right?
Any clarification would be much appreciated re: … Is this issue present in Cubase Pro 8 versions?
