I am timestretching a long guitar piece that I'd like to export as a .wav file. Sounds great when I play it in Ableton, but when I select Export Audio/Video I get a blank .wav file only. I've done a search on this forum & on Google but can't find any helpful info on the subject, so if any of you guys could give me some pointers that would be much appreciated! Here's a screenshot of my export settings:
