Big Noise When Using VocalSync

I've just got around to trying out VocalSync on a harmony-heavy project I'm working on.
 
I designated a lead track as the reference, then selected a region in a harmony track to sync up with it. I see the waveform above the line shifting around as I turn the dial. So far, OK.
 
But when I try to play the selected part of the song to hear the effect of VocalSync, I get a horrendous bass noise. It sounds like feedback, as if there's a loop somewhere. It continues until I remove the Region Effect, or close the project.
 
Has anyone else has this problem, or even better, solved it?
 
Thanks.

Thanks, Noel. Should I attach it here or send it with a support request?
 

It may not be the same issue, but I had a similar experience due to a reverb plugin on the reference track (a slight oversight on my part).
 
I removed the VST from the FX bin, adjusted the sync, rendered the harmony track and reinstated the reverb.
 
(I also had to comfort my dog, who almost fainted when the feedback loop kicked in).
 
 
 

I also made a fresh project consisting of two short vocal tracks of me counting to four, plus a Master bus, a Vocal bus, and a Reverb bus.
 
I get some minor ticking artifacts, but nothing like on the other two project I tried VocalSync on, nor like the cut down version that I sent to Noel.
 
In the fresh project, I can route to the main outs, Master, or the Vocal bus, with or without a send to the Reverb bus, and all I hear is the minor ticking.
 
Weird. 
 
 

The only problem I saw in his project was that the prochannel Rematrix Reverb had somehow no waveform loaded and therefore was silencing the entire reverb bus. After I selected a preset it worked fine.

There's a 1.089 driver available for fireface:

.. and a firmware update below it.
 
Geforce drivers here:

Clean/custom install, avoid installing the audio drivers.

Thanks, Doktor Avalance. I'm using that, despite my signature.

 
Including the firmware update, and the geforce driver?
Might be worth updating your sig, might save some time :)

What happens if you increase the latency? Just grabbing at straws here, but sometimes straws work.

That's a GREAT line man.

Are the ticks registering a high level on the meters?  Further, if you render the vocal sync region, do the ticks/noises go away?

Probably not helpful,
 
when that update (with vocal align) came out i found out pretty quick that I needed to turn off the effects bin and any sends on the reference track.  Other then that I find it hit and miss.  On one doubled vocal a few days ago.  When I dialed up the dial, it made it more OUT of line.  ??  and no most of the time live preview does not sound good have to render and then undo if not right.  
 
 

I can confirm that sometimes there is a horrendous noise when playing vocal synced tracks in preview mode. On my system it sounds like I knocked over an old guitar amp with a spring reverb, except it's louder than all other tracks combined. The sound subsides in several seconds just like a spring reverb, too. First time it happened I almost fell off my chair. It is so intermitent I don't know if I can duplicate at will. It's happened a few times, and rather than troubleshoot (since I'm always in a hurry) I just work around it - either try Melodyne, V-Vocal, do it manually or just decide it doesn't need alignment. I'll take a closer look next time and post findings back here if this issue doesn't get resolved.

I had it happen again recently. I switched the outputs of both vocal tracks from "Master" to my hardware outputs, and it stopped.
 
Not a satisfactory solution, to be sure.

I've had similar problems with Vocal Sync. The noise may go up to 99.9 dB (!!!), and it never happens once you render the clip. It starts (AFAI rememebr) already before you do any changes.
 
Me, too, is using RME, albeit the 9632 card.

This is exactly what happened to me (I reported it in another thread). It sounds like, as you said, like when you drop an old guitar amp with a analog reverb spring. The meters get slammed and the noise is damagingly loud.
 
Actually it was similar to a shotgun blast in gymnasium. Fudged up my ears for the day the first time it happened.
 
However that extended noise is from any reverbs downstrem from the clips. I had a mild reverb set up via a send to an FX bus. Once I turned off the verb the extended sound went away.
 
All that remained was extremely loud but extremely momentarily "pops". Those pops were the same volume as the sound with the reverb on. So I'm guessing the pops are so loud they hit the reverb and it gets repeated. As I said my verb was very light to the point you could barely hear it (it was just to give a small bit of room effect). The fact that the reflections/tails were that extremely tells me those pops are probably the loudest thing every blasted through my system (and I used to get that Dim Pro crash noise from browsing/previewing too many patches which was also insanely ear shattering).
 
So word to the wise... when using Vocalsync TURN OFF ANY REVERBS BEING FED BY THE VS TRACK(S) if you want to avoid hearing/equipment damage!!!
 
After all that I found Vocalsync to not be very useful anyway. It KIND of worked for some phrases but inevitably at least one or two syllables wouldn't sync or synced the wrong way (opposite direction... and these tracks were really close already).
 
I ended up having to just do the corrections using Audiosnap by hand which worked much better and actually easier than VS without the noise. Audiosnap seems to be working much better than my previous experiences so I'll be sticking with that.
 
VS is a nice idea but it's a little gimmicky and due to this noise issue and the fact it doesn't seem to work as well as advertised it's just not that useful to me.
 
Others may have a different experience and it's worth checking out but I was REALLY ticked off that I lost a day of working on something because my ears got smashed like that. It's bleeding dangerous and there should probably be a warning put on it. The noise was that bad.
 
Cheers.
