Hi Lars,
I am having a frustrating time playing back a project I am working on in Cubasis 3, it has one audio track and numerous midi tracks, the latency has been adjusted to a 21.3 ms to keep it stable, the DSP and CPU are very low.
When play back has started, the playhead judders as it moves along the screen and suddenly it jumps and misses a beat! If I stop halfway through a bar for a moment and then hit the Play button, everything is out of sync, it sounds like a troop of drum solders trying to all march in step together! I have to position the playhead at the start of that particular bar to stay in sync.
This started as soon as I enabled the tempo track because the audio I was working with speeds up slightly and then slows down again, I used the tempo track to track this speed variation, but since the juddering has started, turning off the tempo track makes no difference.
I have examined every track to see what’s going on, but I will duplicate this project and whilst working on the duplication, I will delete all tracks one by one until I find the rouge track!
Just thought I would mention it in case anyone else is having issues with juddering.
Everything is updated, I opened a new project after rebooting the iPad, but I would have to build this new project up until I reach the juddering point….if it does even happen again I don’t know.

UPDATE
I have deleted every single track from my duplicated troublesome project, but after deleting everything, the juddering still persists, so I have shut everything down, rebooted my 13” iPad Air M2 and created a new empty project in Cubasis 3, I screen recorded the erratic behaviour, no other apps were running in the background.
Whilst Cubasis 3 is unstable I can no longer use it.
It is 7.20am and I have been up all night trying to sort this problem out.
Here is a screen recorded video showing the erratic behaviour even with an empty project.

We are sorry to read about your issues.
From what I can see in the video, Cubasis seems to run fine, but just stops after some time (which might be expected since it is an empty project).
Please let us focus on your initial problem:
- Are you able to provide us with a short clip, which shows the playback issues?
- Do you have a project to share, which allows our engineering to reproduce the issue?
Thanks
Lars
Hi Lars,
I have just played the video I uploaded using the Dropbox link and it shows an unsteady playhead movement, each time I play the original Cubasis test project the juddering occurs in different places.
I will find a small project and send it to you, the project I am working on at the moment and the one that is causing me problems with juddering is 148Mb in size, I think the extra large size is for the fact I am using a few instances of the Yamaha TGX-85 synth, each one has 85Gb of samples, plus many other synths, the DSP does not show any signs of excessive workload.
I’m sorry Lars, I have just discovered something:
I have just loaded a completely different large 475Mb Cubasis 3 project into both iPad Air 4 and 13” iPad Air M2, the Air 4 runs smooth and trouble free, but the 13” Air judders on playback, so I will try and find out what’s causing the issue by comparing settings etc between the two iPads, I know the 13” Air is more powerful than the Air 4, so it has to be something I have done by mistake.
I will let you know the outcome very soon I hope.
Mike
Thanks for your reply.
So it seems the issue is unrelated to Cubasis?
You may give the following steps a try as well:
- Close all apps, including Cubasis.
- Fully shut down the iPad (turn it off).
- Restart the iPad, and load Cubasis with an empty project template.
Does this help, resolving the issue on the iPad Air device?
Best,
Lars
Thank you Lars, but I have already done this when I could no longer find the problem, but after just comparing the Cubasis settings on both iPads, I noticed I somehow enabled the Mackie Control on the 13” iPad, I probably did it a while ago when I was trying to get SampleTank working, I have now disabled the Mackie Control and Cubasis us back to normal.
The solution was such a small and easy task to put right, but hard to find considering it was staring me in the face every time I opened the Cubasis settings!
