Hi and welcome,
In theory it’s not necessary.
You have an option to Record from a Channel Output:
- Add a Group Channel.
- Route your LopMash output to the Group.
- Add an Audio track, and set it’s input as a Group Out. Make sure, the output is set to Stereo Out.
- Record
Cubase Pro only.
You can Export Audio Mixdown > Batch Channel Export, and then import it back to Cubase project immediately.
In the current Cubase, you can use Render In Place feature.
