[CB-4475] Audio track disappears after crash Cubasis ios

I recently created a project in Cubasis.

Track 1: synthmaster one (freeze)
Track 2: Sunrizer (freeze)
Track 3: classic machine bass drum
Track 4:classic machine snare drum
Track 5: classic machine hi hat
Track 6:Guitar (Audio track)
Track 7: Guitar (Audio track)
Track 8: Guitar (Audio track)

All playing fine, pressed stop (play on Cubasis)
When I pressed to play project again light sounding click, Cubasis crashed (closed itself)
When I reopened Cubasis track 7 Guitar Audio had deleted/disappeared?
It was not in the media bay, nor the trash, took me a few hours to get to this stage and was very disappointed at this…
I think this needs to be reviewed in order for it to work without these issues.

If you spend time & effort in creating a project to be let down by the app crashing and loosing
Part of your work it is then time to seek other means, I am not putting Cubasis down in any way, it’s a great app but does have its issues.

I only hope the next update will fix any on going issues.

Hi Cubasis99999,

We’re sorry to hear that!

Unfortunately, the use of external instruments and/or effects apps - depending on the apps in use - can lead to unforeseeable issues, unrelated to Cubasis.

Please provide us with a detailed bug report, to have the issue evaluated by our team. Additionally please provide us with the project, and a short clip that visualises the issue.

Best wishes,
Lars

Hi Lars,
I thought that once a track was frozen it then becomes an audio track therefore the third party app ie: Synthmaster one is no longer running as an AUv3

It will be difficult to add a screenshot or video as this is a random issue, I have sent a bug report for the crash

If I try to reproduce it again there is no guarantee it would crash,
I click on play and Cubasis closed, upon reopen the Guitar track had gone,
I create many projects using guitar and seldom have this issue, but when you spend 2-3 hours and this happens it is extremely frustrating

I will re-send bug report in the hope that there maybe a way round this issue happening again

Many thanks

Hi Cubasis99999,

Thanks for the crash report which I’ve shared with our engineering.

Unfortunately, most of the time a clear repro is required to analyse the cause of an issue.
As stated before, using third party instruments/effects apps can lead to unforeseeable issues, unrelated to Cubasis as well.

Will keep you updated.

Best,
Lars

Thank you for taking the time to respond Lars,

Hope this can be fixed…

Best wishes.

Hi Cubasis99999,

Thanks for your message and great support.
There is a small chance, that the crash report will help to address the issue with the next update.

Let’s see…

Best,
Lars

Looking at your track name list I’m seeing that it could also be related to what I discovered here
