...I even made a very short video on how to reproduce the problem using a single VST plugin on master or sub-master buss on V13 and V14....

Any chance of sharing? You can upload a video direct to the forum using the circular blue icon with arrow in it when you compose a comment.

I tried to recreate this problem and I can only get the glitching when I resize the FX window.

If anybody wants to reproduce the problem, here is how to proceed:

- create a new project on a 64 bit version of Vegas, using any ASIO sound card

- insert few tracks and few busses

- set few tracks to go to a same bus

- insert any third party 64 bits audio plugin on the bus (Waves, Fluxx, Sonnox,...)

- while playing, zoom in or out, scroll the tracks left/right or up/down, or try to change any plugin parameter like the frequency in a paragraphic EQ or sliders in a reverb...

It should glitch...

I had trouble uploading the 1 minute video to this page so here is a link to the video on YouTube

If this doesn't work please let me know and I'll try uploading here again.

Please note, I have since discovered that it occurs only when adding VST plug-ins as master effects,  to busses or master buss NOT individual tracks.  They seem to work fine there.  But a typical mix session can easily have 4 or 5 master effects, 5 or more group busses with several plug-ins each and always a couple plug-ins on the master buss.  Again we are talking VST plug-ins NOT the plug-ins that come with Vegas.  As you add more plug-ins the worse the problem gets.  A typical session stutters constantly without resizing the screen or touching any parameter.  I could make a quick video of this happening if that would help you.  Changing or maxing out the buffer improves it only slightly but still unusable to mix.  Also I don't know if this helps but I can render a big mix with playback stuttering to a stereo file and it plays fine.  And again, if I go back to my trusty Vegas 9 32bit these sessions play perfectly using almost zero CPU, memory and hard disk resources.

I tried with 3 stereo audio tracks routed to 1 of 3 audio busses. I added Waves FX from the Musicians 2 bundle such as Rennaissance Vox or Doubler. I got no glitching while playing, zooming in/out, scrolling, or changing parameters.

I do get glitching when I change the size of the FX window as in michael-mcdonald's demo.

I'm using VP14 build 252 with M-Audio M-Track with driver 1.0.6.

The last time I tried I was under Vegas 14 build 211. I just updated to build 252 and I'll give it a try tomorrow...

Thanks Nick for testing. Can you try with more plugins on the bus 1 please? Or on another bus...

And when I get a break in the next day or so I'll video a real world 18 tracks session so you can see and hear how badly it breaks up without even resizing the screen.  Then how the audio gets better and better as I remove VST plug-ins from the sub and master busses.

With 4 tracks on 1 bus and 10 VSTs on the bus I can induce a little bit of "crackling" as I move some controls or zoom in and out or scroll the timeline. If I didn't know this is thought of as a bug I would have just assumed it's because I'm overloading it. I'm not an audio guy; the most VSTs I would use would be say 2 in a chain. Also I have a powerful PC with 32GB RAM. Full specs in my profile.

Hi Nick, here are a couple quick captured videos.  This first one shows Vegas 14 build 252 running an average audio session at 44.1kHz 24 bit having a lot of trouble playing back with VST plug-is in the sub and master busses.  Then as video plays I start removing the VST plug-ins and you'll hear the audio start to clean up as I do.  As you will hear it is not possible to mix with this kind of playback sound.  The computer is a Sweetwater Creation Station top of the line i7 running a MOTU 424pcie card and 2408 Mark III interface, Windows 10.  In both videos I show you with the task manager the CPU, RAM and Disk usage so you can see the computer is definitely not being  overloaded. 

Then this video is the exact same song file with the exact same VST plug-ins running in Vegas 9 32bit.  In fact this video has 2 additional VST plug-ins that are power hogs and the playback is perfect.  Running on the same computer.

Hope this gives you a better idea as to what we are dealing with.  Let me know if I can get you any more info.

Great demo Michael. Really clarifies the problem. Thanks.

I think it's worth replying to your last email from Support on this issue, giving them links to these videos. It might come back with a reply about the ticket being closed, in which case you could try submitting a fresh support request. Issues seem to get into the developers' bug database and reach the right people more reliably through support requests than through the forum.

Thank you very much for these videos !

I requested a support ticket and sent the videos.  On June 26 I received email from Magix. "I have just confirmed that this is a logged bug and will most likely be fixed in a later version. Thank you for your information."  Most likely, hmmmmm.  I installed Build 270 but problem still exists if anyone was wondering.  And the hope continues.

Now vegas 15 is out and audio stuttering is even worse then in 14 :(

The sound engine of Vegas on my observations became "limp" starting with the 10th version. Here's one example: create 100 empty audio tracks in project 5.1 and turn on automation on all the tracks . Playback in version 10 and higher does not even begin (no matter how powerful your computer is). But in Vegas version 8 I can create 1000 such tracks and more - and there are no playback problems. In this case, most likely the problem is in the GUI, but it's impossible to work anyway. Therefore, and also because of the lack of a real 5.1 bus, problems with VST, I did not update after the 10th version.

I am not surprised, They did not address any audio issues in their pre-release press releases so I was expecting nothing. Again I am left with having to believe that Vegas no longer cares to be even considered as a DAW and may only address these issues when they absolutely have to, to appease their video customers. I am using Reaper now and only using Edit 14 to lay out my CD projects.

OK, here's the Vegas 15 (build 216) initial report. Thanks for everyone's input on this issue. We're still hoping for a Magix style solution.

My problem has always been glitching and stuttering when I added VST plugins (especially iZotope Nectar). The stuttering occurs when zooming in and out and when mouse passes over the waveform on the timeline.

There has been progress in 15!

The glitching now occurs only when zooming NOT when mouse passes over waveform.

Incremental improvements but looking forward to the final solution.

I guess you'll just have to wait for the version 16 or 17 before that gets fixed, I'm not upgrading from 14 despite having bought every upgrade since 7, because Magix doesn't deserve my money for the garbage 14 is. I'm can't see any sane reason to give them any more money after that rip-off. I'm insulted by the offerings that magix have served. Wow, it's unbelievable really.

I've been trying to be respectful in expressing my disappointment. Like I have stated before, rather than think that Magix is not competent and does not know what they are doing I am choosing to believe they know exactly what they are doing and I along with others like me no longer are part of their target market. So if and when their product fits into my world rather than I fitting into their products, I will use something else.

 

Problem still persists with Vegas Pro v16 and Waves v10.

:/

The stuttering only appears on live previews. Rendered files are ok (in my experience)

To recreate the issue;

1) Open a new project in any 64 bit Vegas

2) Import an audio track

3) Open Audio FX pane and load a Waves plugin (L2 Maximizer, SuperTap etc...)

4) While plugin pane is open and Waves plugin GUI is visible (selected), press play and preview the audio

In a few seconds, audio playback starts the stutter as if CPU can't handle the load. GUI of Vegas also stutters during this. (vu meters and cursor animations)...

Wow, cannot believe they have not fixed this. As I stated before Magix has left me no choice but to believe they understand this problem and are intentionally ignoring it. Audio and the DAW market no longer interest them at least as far as the Vegas line goes. I am using 14 strictly to lay out CD projects and burn redbook cd's and that is it. I will be looking for a CD creator program that is cost effective and better suits my needs. Another issue I seem to be having in Edit Pro 14 is I can load multiple audio plugins but can only open and view one at a time. That seems strange maybe I am over looking something. In Reaper I can open as many as my video screens can handle at once.

How sad. I'm glad I found this info before even bothering to contact their support. My hopes went up prior to the release of V16 as their latest Acid Pro included support for VST3. Downloaded the demo and could confirm any third party VST worked as it should within the host. The capability seems to be there, so why this wasn't done for V16 who knows. This constant issue, plus the inability to have more than one plug-in window open at a time, is the nail in the coffin for me. Fortunately I can switch the workflow over to another app (one which has no issues with plug-ins, multiple windows open, etc.) and only use an old version of Vegas for a single operation. Shame. I'd like to think it could still be fixed but so doubtful at this point.

Yes I have given up on Vegas, They obviously know about this and have CHOSEN to not fix these audio issues. So I have CHOSEN to move on. Reaper is now my main DAW . I lay out my CD projects in Vegas but that is it.

Same here guys. I never had a problem with Vegas 11. I've got a MOTU Ultralite MK3 and a pretty speedy computer. I seem to have the biggest trouble with Waves plugins, but admittedly I haven't tried many others. I use RVox for my voiceover, and that one VST plugin alone brought all playback to its knees. Recording was interesting too. I got BT-style stutter edits. Really frustrating!

(Run Vegas Pro 16 307) Newbie to Vegas but not audio. Waves Plugins V10+ even with WSG Server One DSP, as well as using "Low latency" & "Live" versions of the plugins still just causes Vegas to fail, with serious video & audio glitching. PC resources, powerful dedicated DSP & audio interfaces run my DAW w/high numbers of Waves plugins & all plugins without issue at very low latency of 2-6ms. Drop LL L3 in: & playing all, including stops. Softtube plugins won't load yet show up in the same FX list as all Waves, other 3rd party & Vegas audio FX. (iZotope, BIAS).

I get Waves, but that none seem to function in a small project makes me wonder what I'm doing wrong, (missed in optimization?), as all are 64 bit, licensed versions & despite re-optimizing after I installed & updated only Audio FX that come with Vegas all work. Yet none are near the quality of the plugins I rely on. so I master externally.

Waves Audio & Magix say they don't support each other but if anyone has a different experience due to their PC expertise work around, please advise! Mastering in Cubase Pro/Nuendo by importing video tracks" there" is easy, w/an excellent video engine in Steinberg products, then I re-import to Vegas, that's how I work. Love Vegas but a bit surprised.
