Anybody else get this error when flattening?

Nope. I use a Mac

What is in the track that you are flattening?

A Vst could be the cause of the issue.
Perhaps upgrade to the latest version of that VST then try.

I have experienced similar issues with VST plugin in Live on Mac.

Yup. I just had a problem where I couldn't render my project to send to a client because Live would crash. I tried flattening each track individually until I found the culprit - two tracks that I had, both routing to one instance of Kontakt. Oddly enough, the third and fourth tracks routing to that same Kontakt flattened just fine. I had to resample the tracks as a workaround. Huge PIMA, and the Abes got an assload of crash reports.

Oh, and this was on a Mac.

I don't know if this is still relevant for anyone, but I was experiencing this too and it was KILLING my workflow.

A workaround:

If you're freezing and flattening in arrange mode, make sure there are NO clips in session mode on the track your freezing. Then freeze. Then flatten. No crash.


Another workaround:

Freeze the track; create a new track; drag (or alt+drag) audio from frozen track onto newly created track. No crash


I was only getting the crash on the flatten, so if this affects you try integrating either of these workarounds into your workflow.

10.7, Live 9.1

hope it helps

Aporia, you are a god. That last workaround worked perfectly

Thanks for sharing.

7 years later and Iv just had the same issue. Nice to see bugs being addressed haha

Cheers for the workaround though.. worked a treat!

Make that nine years!
