Well done Sir!
I was going to test it myself, but you have done the job for us.
I thoroughly ask Cakewalk by Bandlab to ADD a 'possible' ... Export whole project as... - if ever possible!!
Thanks
PS I actually asked BitWig if can import CW, they said no, but said thanks for the suggestion - maybe there is a hope to save time (I am kind of getting pulled in with BitWig - very nice application - at least, for a nerdy point of view)
