Hi,
I am having a problem with stems.
I have just upgraded my windows computer from an Intel i7-770k & nvidia RTX 2080, to an AMD Ryzen 5900x and nvidia RTX 3080.
Stems worked perfectly fine on my old system, using an MC6000 controller to control them (inner knobs as stems, outer as EQ).
Now though, stems just don't work at all. When VDJ first loads up the knobs on the screen are showing as vocal/instrument/beat, but after a few seconds they change to high/mid/low, and the inner and outer knobs on my MC6000 control the EQ, the stems don't appear at all.
Additionally, the hot buttons in the stems section do nothing either. turning any of the 5 of them on or off doesn't affect the music in any way. I have also tried loading songs that have pre computed stems and they don't work either.
I tried changing the math engine in the settings from GPU (which is what it was on by default) to any of the other options, but that just crashed VDJ. I manually changed the setting in the settings.xml file to CPU, stems still don't work. Automatic doesn't work either.
Another thing I have noticed is that When I close VDJ, if I then open task manager it's still running, and if I try to open VDJ again it won't load my library, which seems like VDJ isn't shutting down properly either.
I think there may be some compatibility issues with my new CPU/GPU. Stems is a great feature and I'm really lost without it!
Anybody got any ideas what might be the problem here?
Thanks.

Could you try to open VDJ, wait until stems work normally, then change mathEngine to CPU and then restart to see if they work faster that time?If it would be related to the nVidia it should initialize fast when using CPU.
If not fast, could you check agian in process explorer where it is stuck?

Just been doing some more playing around trying to get this to work.
I was using a backup of my Virtual DJ folder in documents, so I decided to do a fresh install of VDJ to see if that solved it, and it worked absolutely fine until I closed VDJ down. As I said above, it doesn't actually close, just goes into background processes and I have to force close it before I can start VDJ again. Upon starting up VDJ again, stems don't work again.
I did notice there was a text file in the folder called 'Log Report', which contained a load of references to the mathEngineInit freezing:

These times correspond to the times when I close down VDJ and it doesn't close properly. Looks like the math engine is crashing when I am exiting VDJ.

So, I just left VDJ open for a while as I noticed that it was using quite a bit of CPU power for it not actually doing anything. Went away for about half an hour, came back and stems are working! The waveform had changed form the multicoloured to the one colour, and the eq knobs/pads are working. Loaded up a few songs from tidal that I know I would have never played before (so no precomputed stems) and it analysed them in a couple of seconds.
I then closed VDJ, and it didn't hang around in the task manager like it did before.
I opened it up again, and stems were not working again. Left it open on my monitor and watched it, after about 15 minutes the waveforms changed and it's working now. CPU usage dropped from about 6% down to less than 1%. Seems like it's doing some kind of background task that is taking a long time, then once that finishes everything else works fine.
It's a good workaround for now, but would be good if this could get solved so stems work when VDJ first starts! Happy to provide any log files needed.

Does yours also start working again if you leave it for 15 mins or so?
Definitely seems like it's a 30xx problem then seeing as we have different processors.
Edit: just seen your thread. Sounds identical to my issue.
There was an Nvidia Driver update out today (461.09) but installing them hasn't changed anything. I tried downgrading to an earlier version (457.30) to see if that solved it but it didn't.

It is kind of random about it's around 15-19 mins every time I've timed it using the in software timer (click the clock). Yeah I saw the notice but sad that does not fix it so must be something calling the API to use cuda processing.

So I streamed a set last night after leaving VDJ open for 15 mins beforehand to get the stems working.
I noticed that stems just aren't even working properly! I'm using the EZRemix option for the EQ knobs, but they aren't doing what they are meant to do, and even using the stems pads isn't working properly either.
Using the pads:
Turning off Vocal doesn't seem to do anything
Turning off the kick mutes both the kick and the vocals, but then turning off the HiHat as well brings the vocals back
Turning off the Instru and Bass buttons just seems to mute random frequencies!
Tested this with a few different songs, so it's not just the 1 song I tried. Video here of proof: https://1drv.ms/v/s!AirDBud1EdbfsPR_h5jlBIXD7Gcx1g?e=TebXYS
I've played Killing in the name many times before and I know the stems worked properly on it before.
I also tried setting the MathEngine setting in the settings.xml file to CPU to see if this made a difference, but it's exactly the same either way.

I waited for 15 mins till it finished doing everything and brought up the single coloured waveform/stems buttons started doing something. Changed the Math Engine setting to CPU and VDJ didn't crash like it was doing before. Stems still sound like they did in my video above though.
So I restarted VDJ, and the MathEngine setting has stayed on CPU. Loaded up Killing in the name but it still sounded like the video above, so I tried a different song that didn't already have a pre-computed stem.
SUCCESS! It works like it should. I went back and recomputed the stem for Killing in the name and that also works ok now as well.
Restarted it again after and no slowdown, stems take a bit longer to compute but it's still only 10 seconds or so.
For reference, I ran Process explorer while I was waiting the 15 mins for it to start, and there was 1 process (virtualdj.exe+0x26caef8) that was using nearly 5% of my CPU. Digging into it further and double clicking on the line that was using all the CPU in the properties window showed it was using this below:

Huh, I have no idea why that doesn't have sound!
Either way it's working with CPU as the MathEngine now rather than GPU.
Unless you specifically want a video of it not working? I can reupload it if you need me to.

I recorded another video with sound this time, demonstrating that stems do nothing when VDJ has just loaded and is using loads of CPU, stems not working using GPU as the MathEngine, and stems working fine using CPU as the MathEngine.
For reference, my hardware is:

Timeline:
00:00 - Loading VDJ, showing MathEngine set to GPU
00:12 - Demonstrating stems buttons doing nothing (the first few bars sound weird in the video but they sounded normal on my system. Probably just the video compression). Waveform is coloured at this point which I guess indicates that stems haven't been created. EQ still works as normal.
00:36 - starting timer in top right hand corner
00:40 - showing that VDJ is using about 6% of my cpu
00:48 - Sped up footage of me waiting for VDJ to finish doing whatever it's doing
01:26 - VDJ loads the stems in, waveform changes from coloured to all blue. CPU usage goes down to about 0.5%
01:47 - Demonstrating stems not working properly with MathEngine set to GPU
02:41 - load a different track into Deck 1
02:44 - Change MathEngine setting from GPU to CPU
02:51 - Reload Killing in the name into Deck 1. Stem is calculated again by VDJ
03:01 - Demonstrating Stems working fine with MathEngine set to CPU

Hi Nemo, please check out all my findings on my thread about very similar behaviour. I have amd 4800 h Hp pavillion 15 laptop with latest Nvidia drivers for a graphice card too. I am now 5 days down the line and my problem is being escalted higher at HP as my laptop is 2 months old and in warranty. I must say HP have been superb so far with their work and i am working through diagnostics with them daily, expecting another call from them tomorrow so will let you know.
Have you tried running A small piece of software called Latency Mon? Its tiny and free, it will monitor any processes that spike in the background to cause video and/or audio problems. This was one of the ways we started our investigation in to the problem. I would be really interested in what was causing your problems.
The problems that are causing my spike are related to the same new Nvidia drivers as a guy earlier in this post but even rolling back drivers it still happens and causes my nvidia drivers to fail leaving me with the miles inferior amd radeon drivers to work from
The main culprits for the problem it seems are:
Nvidia Windows, Kernel mode drivers &
Kernel mode driver framework runtime
Anyway here is the thread, it seems many of us are having similar problems. https://www.virtualdj.com/forums/239355/VirtualDJ_Technical_Support/New_VDJ_version_Crash.html
