Varispeed - how to show new time length?

Hi,

Is there a way I can see how long a varispeed-adjusted track will be before I bounce it?

I need to do 15 and 30-second edits of my full songs for advertisement use.

My tracks sometimes come out a little too long or short, so varispeed is a great tool to adjust the tempo/timing of the song to make it exactly 30 seconds, for example.

I've been adding a secondary ruler to show time, and then the time shows in the selected cycle area, too. This way, I can drag the selected audio to exactly 30 seconds.

HOWEVER, when I use varispeed to speed it up or slow it down, it still says the same time length in the cycle bar. For example, a 33-second track played at -3% is shorter in length when I bounce it. But this new time length (after varispeed it's 30 seconds, not 33), does NOT show in Logic as I experiment with the varispeed. Even if I do the 33-second track at -50% in varispeed, it will still show 33 seconds in the cycle bar, not 16 1/2 seconds.

What do you suggest for knowing the new time of a track after varispeed is applied?

It seems like there must be a way besides my bouncing it and then re-importing the bounced track.
