[Solved] Bounce to track

When you say "there's nothing there", do you mean no clip at all, or you get a clip but the signal is a flatline? And is this with pure audio tracks - no MIDI/synths involved? If it's a flatline clip, make sure you don't have something else in the project soloed. Basically, if you can't hear the selected tracks on playback, you'll get a flatline on bounce. If there's no clip at all, possibly the destination track is not as you intended. I would suggest that you create the target track in advance and choose it as the destination for the bounce. It shouldn't make a difference, but it helps keep things organized.
 
Also, rather than bouncing entire mix, if you don't have FX on buses that you want printed to the bounce, try selecting just Tracks as the source. If you do want bus FX printed try selecting Buses as the source. Again, it shouldn't make a difference, but I like to control exactly what sources go into a bounce - no more, and no less.

This is a common error. It's worth checking out the various bounce and export options, it took me a long time to realize how useful export with only tracks selected could be!
