Thanks for the help guys. I was considering doing the delete the empty space from the master in another editor thing as that's what I used to do with Cakewalk 8 and Studio5 through Soundforge 14 years ago. I figured that must have changed by now.
I've still got Soundforge on a CD somewhere but there must be better utilities than that now. Or a new version.
I actually tried the select region to export but must have stuffed it up as it came back with an error "no audio selected" or something like that.
BTW I tried the insert midi events and then Delete Special / Hole for all tracks but that seemed to delete the empty measures for some Midi and Audio tracks but not others, stuffing up the track sync. Ctrl Z.
If that's the way to do it that's the way to do it. No deleting of empty measures for me.
Thanks again for the help.
