Hello all, sorry for the lack of activity on this thread.
There is no current way to delete a track, the closest form of deletion is re-recording, which does “delete” the original recording once you replace it. We are working on a part deletion option which is detailed on my post to this thread. Any undone layer (base layer/overdub layer) that is re-recorded will ‘delete’ the undone material.
We are working on undone logic so that they behave more like empty tracks, this will make deletion less necessary.
The only way to “delete” currently (as of 3.1.10) is to delete the entire song, which deletes any saved data for that song.
I will be tagging this as duplicate in terms of part deletion request, I will tag as #not-a-bug because we will not be creating a delete track command as of now and this is not technically a bug, it is made to be this way.
Thank you
