Hello,
 
I'm currently working on a film score in X2a, and need to render a cue (export audio) about an hour into the film. I usually work on shortened segments, but in this case I loaded the entire video. My question is, is it possible to export the audio from the Now Time instead of Sonar rendering the whole file from the beginning?

Select all the tracks to export then the Select From = Now either from the Edit > Select menu or Control-A then Control-F6

SCOOK, thank you so much! I gave it a try, works perfect. After all these years LOL!

You are welcome. If you noticed the Select submenu has several select options. To select a range to export for selected tracks click-drag across the timeline.
