So I setup tempo to 142 bpm, I bring in AD2 grab a pattern and drag it into the AD2 track, convert to grove clip and stretch it out to like 5 minutes, then bounce it to a wav. Now record like a rhythm track and then some vocals.
 
I export that as a wave/backing track and import it into an empty project that is also set to 142 bpm.
So why did the backing track slow down?
 
Why does changing tempos never work anyplace in Sonar Splat and why is the drag a track to the top to find out true tempo never does anything but read the tempo? Can't change tempo anyplace!!! I needed to speed up the tempo of a track... Why can't I change the tempo on the control bar? (right under the now time)
Why was I able to do something so logical and simple in Reaper and not in Splat? Not even have used Reaper before it took seconds to figure out...
 
 

Thanks to all who helped me :)

Changing tempo via the control bar changes only MIDI data. Changing audio data requires either converting into a groove clip or stretching via the offline, high-quality stretching algorithm or Melodyne. 
 
You might find the Friday's Tip of the Week for Week 33 on changing tempo for an entire project helpful.
 
Note that some DAWs do offer a seamless tempo change. The upside is it's convenient. The downside is unless the change is small, there's a tendency to product artifacts. The method described in the tip is more time-consuming to implement, but maintains fidelity well.

Thank you Craig I will check it out. :)

Hi, I checked out how you say to set it up. Seems confusing to me.
But earlier I found someplace in the 2016 9 doc that said to use grove clip.
So what I did was just change the tempo on the control bar and selected all tracks, right clicked on a track and clicked on grove clip looping. I don't know if that's right but it seemed to work great. This was something I was unable to fine in 2016 6 (The doc I had been using) so maybe its relative new?
All I know is that I don't have to re record drums again. ha!
 
Peace!
