app crashed in the middle of ppl dancing

Xten · February 11, 2024, 5:02am

I had a crazy crash in the middle of a packed dance floor 10 mins. into a set . I am soooo upset . This didn’t happen with the old app . Why is this happening ???

pls tell me why this happened and what I can do to resolve this

I am running a MacBook Pro 2020 M1 chip with Sonoma 14.3
8 GB Ram
512 GB SSD

I’m sorry to hear that, I have never actually had a crash just one deck momentarily stop and I just pressed play again,

What exactly happened and did you have to restart the app?
Did you continue playing without any further crashes?

I was using crossfader function in djay pro 5 and pioneer controller DDJ SX when the crash happened last night … the floor cleared out when the crash happened and when I restarted the app , I only ran it for 2 mins or so bc the ppl started to leave I updated bc a few days ago the older version crashed right away at home as soon as I opened the app … I have attached both bug reports… im super upset that this happened . this was the first time the app crashed in the middle of a set for me … I have had crashes at home without a controller , but I don’t really care when it happens at home

Xten · February 11, 2024, 8:58am

I have also had just one deck momentarily stop a few times but that’s not as bad as the entire app crashing … so I am not too upset about the monetary stoppage but the whole app crashing is an entirely diff animal :(((((

PKtheDJ · February 11, 2024, 9:16am

@Xten please note, you do not have to post a new message every time you want to add a line or two. You can edit the original post (click the pencil).

maurizio_T · February 12, 2024, 1:39am

That’s the issue I have had a few times when using my iPad and Rane One,
Before every set, I shut down all apps and disable bluetooth,
I then perform a hard reset on my iPad and only open the Djay app…

This procedure seems to have fixed my issue

Slak_Jaw · February 12, 2024, 12:31pm

Hi @Xten,

Sorry to hear about this. I’ve been in that situation myself so I know how devastating it is. Crash reports are automatically submitted to the engineering and support team, but I wanted to offer some help in the meantime.

Given that you had a crash on the older version of djay Pro before your gig, this makes me think that there’s something else contributing to this issue.
Have you recently updated your macOS, installed new software on your Mac or added any new hardware to your setup? WiFi or Bluetooth ON?
Were you running any other apps or perhaps an iCloud/Time Machine backup when the crashes occurred?
Below is an article on optimizing your Mac for DJing. I follow a very similar checklist on all of my DJing devices: How To Optimise Your Mac For DJing - Digital DJ Tips
Here’s another more recent article for Mac and Windows laptops: How To Optimise Your Mac Or Windows Laptop For DJing In 2024

Xten · February 15, 2024, 12:50am

No new hardware added. Like I said , I did update to Sonoma recently . wifi was off but bluetooth was on.
3.Wifi was off , but bluetooth was on and no apps/backups were running in the background. In the past I was running djay pro with wifi on and bluetooth on , even a couple of windows open , and it never crashed like this … like I mentioned earlier , it happened when I was using the crossfader fusion , but I don’t know if that caused it or not.

I was not even streaming from Apple Music or tidal , and using my SSD and NOT an external hard drive.

I have 8 GB RAM and ample space on my laptop , so I know it’s not my laptop bc I don’t have crashes on my laptop.

In your vast experience, what version of djay pro is the most stable and what macOS works best. all these new features are cool and all, but I am looking for stability. Stability is the most important thing for me

I don’t know what to do now … can I go back to an older version of the app … and maybe go back to an older OS. I have been a user for a long time and I pay for this every year … I am nervous about djing with dJay pro now I did attach and send crash reports earlier

Slak_Jaw · February 16, 2024, 9:54pm

Hi @Xten,

Thanks for the additional information. I have forwarded this onto the engineering team as well.
I haven’t really had stability issues with any macOS, iOS or djay version, so I cannot personally recommend anything helpful here other than the laptop optimization tips already shared above.
As for going back to a previous OS or djay Pro version, you can do this using Time Machine on your Mac.
If I hear anything else from the engineering team, I will be sure to share it here as well.

djqueenvic · February 19, 2024, 7:07pm

I feel for you, Xten. Happening to me, but I’m at home.

Slak_Jaw · February 20, 2024, 10:17pm

Hi @Xten, can you please update to the latest 5.1.2 djay version and test to see if this has solved your issue? Thanks!

Xten · February 22, 2024, 4:14am

yes I will do that … and let you know what happens… Thanks

Xten · February 23, 2024, 3:28am

for some reason, It doesn’t give me the option to update in the App Store…weird … I thought the update was released a few days ago… I guess I’ll just have to wait for it to show up … really hoping that this fixes the stability issue… btw , were you guys able to figure out what caused my major crash ? … I really don’t want to switch and I want to recommend this to all my buds… it needs to be stable tho…Thanks

Five-0 · February 23, 2024, 5:07am

Issues with mine also. Deck stopping, performance issues with the rev1 after a couple hours. All at live gigs…

Slak_Jaw · February 23, 2024, 11:12am

Hey @Five-0, if you create a separate Question or Bug Report topic and provide specific details about the issues you’re experiencing and can try to troubleshoot them with you.

Slak_Jaw · February 23, 2024, 11:22am

@Xten that seems odd. What region are you in?

On a Mac, open App Store > Updates and hit ⌘ Cmd R to refresh the page.
Make sure that you are signed into the App Store with the same Apple ID that you used to buy the app originally.
Sign out of the App Store (not iCloud) and reboot your device. Then go to App Store > Updates to download the update.
Go to the App Store’s Today tab > user icon > Purchased and then search for Things in your list of purchases.

maurizio_T · February 23, 2024, 8:54pm

Is this still happening after the latest update?

Slak_Jaw · February 26, 2024, 2:31pm

Hi @Xten,

Please use this direct link and let me know if you are able to download the latest djay update: Algoriddim djay for Mac, iPad, and iPhone – The new era of DJing
Also, the crash reports we received, appear to be from 2 different computers running different OS and djay versions.
Both of these crash reports are, unfortunately, incomplete. Can you please contact support directly through the djay app on your Mac via Provide djay Pro Feedback. This will allow us to access the crash reports directly. Please do this for both computers so we can access both crash reports. Thanks!
