Cubase crashes reliably when I try to create harmony voices

I have an audio track in stereo. It contains vocals, and I want to extract the (four) voices from it.

When I extract the stereo track (‘create harmony voices’), it works, but the result is… not so great (it’s a jazz vocal section in closed harmony like Manhattan Transfer).

The individual voices are distributed across the stereo spectrum, so I split the track into two mono tracks. When I generate the harmony voice from each of the two mono tracks, it works fine with the left track.

However, Cubase reliably crashes (freezes) with the right track.

All this with the (freshly updated) C14.0.40 on MacOS 26.0.1 (25A362) on a MacBook Air M1.

Do you have any suggestions?

Thanks a lot!

Hi,

The macOS 26 is not officially supported yet.

Does it really crash or freeze? Attach the *.ips file(s), generated by the crash (if there is any).

Mac: macOS Console utility > Crash Reports (or ~user/Library/Logs/Diagnostic Reports).

Sorry for not responding right away – thank you for pointing out that Cubase has not yet been released for 26.01
That must be the point - sometimes Cubase takes three or more seconds to respond after a click…
However, create harmony voices now works…
