It would be great if the channel count for exporting multichannel files can be increased to at least 128. There are some workflows such as working with microphone arrays that require this, for example the spcmic has 84 capsules. I’m able to edit these in Reaper but it would be great to have a single audio file focused editing app like Audacity to support it.
What format are you exporting to? Not all formats support arbitrary many channels
