Topic: Virtual DJ Crash when DVS, sample rate is high, latency low setting
I'm running DVS at highest sample rate and lowest latency but when I load a second FLAC file to the next turntable VDJ crashes. I'm able to repeat this problem, I recorded a video.

Similar issues happen at lower setting, instead of a crash, there is a loud buzz sound when I drop the needle to the cue the next record/song. Quit annoying, I must say, this bug has been around for over a year now. It needs to be fixed!

See the 1min 30second mark of the video where VDJ crashes 2X and immediately reopens with the music nulled out (songs no longer loaded).

I want to run even lower latency, my audio interface/system is capable (0.3ms) but VDJ can't go that low before total distortion/noise. This needs to be address, get rid of the bloat. I can't blend mix music with a sluggish software or update with a new cpu every 2 years.

Which latency and samplerate did you use, and what is the samplerate of the flac files you use

Not sure why you'd need 0.3 ms latency, but assuming your system is capable of that, I'd recommend :
-44100hz samplerate, higher just requires more processing power without any benefit unless you're playing for bats.
-disable master tempo, and set pitchQuality to -1 to fully disable high quality master tempo
-probably disable stems as well

According to the crash logs it appears that stems processing caused the crash btw

Fact is Virtual DJ should never ever crash like that. The low latency setting I used just make the problem easier to replicate. I can start using a lower sample rate and longer latency but after a few songs into a mix, I'll here that buzz sound when I drop the needle to cue the next record. Software should never crash like this.

I have a very low latency PCIE soundcard which absolutely necessary for my ears and performance. The issue is Virtual DJ can be setup to crash repeatedly. Set to the highest sample rate, lowest latency without distorted sound using DVS, playing FLAC files then needle drop the 2nd vinyl and Virtual DJ outputs a loud buzz (very short say 0.5 second) over-riding music playback. If severe enough, the entire software crashes as I've demonstrated in the video. Everything here is repeatable.

I don't like the sound quality of 44.1KHz, but I can make the same thing happen using 48KHz it takes longer though... This is a software bug in Virtual DJ I'm sick of dealing with.
