DJ Mix and Beat Matching with Sonar?

There is nothing as painless as Ableton Live's Advanced algorithm for “instant warping." However, AudioSnap can actually work quite well, but it’s a “combination lock” and you have to do things in the right order. I don’t need to use it a lot but when I have, the following works. These are the basics…there may be something I’m overlooking or some gotcha, but I just did this with a bunch of different songs and it did what was expected.
 

1. Set the desired project tempo.
2. Drag the song file from the Browser or import a file into a track; it’s now a clip.
3. Select the clip and type Alt+A to open the AudioSnap palette.
4. Before turning on AudioSnap, use the Clip Follows Project drop-down menu and select Clips.
5. Turn on AudioSnap.
6. Click on the Clip follows Project button to enable it. The Project tempo should show up in the average tempo box. If you change the tempo, the clip should follow along. 

However you’re hearing the clip in a low-fidelity preview mode. To increase the fidelity, bounce the clip to itself.
 
Notes: 

• If at some point AudioSnap appears to go dead (e.g., you can’t make any changes), just click on the clip again to re-select it.
• If it doesn't assume the correct tempo at first, change the project tempo, then change it back again.  

 
Let me know if this does the job for you. If you run into any problems, please describe what happens as accurately as possible...I know that this does in fact work, so we can probably sort out whatever any issues might be.
 
There are other ways to beat-match, but they take more work so try this first.
 
 

Thanks Mr. Anderton, this works great for me.
How about the "shortcut" in the inspector. 
1. Import the clip via Drag&Drop
2. In the inspector select "AudioSnap" Section of the "Clip" pane
3. Enable AudioSnap
4. Enable to follow project tempo
 
Does this the same job or did i miss an importent step?
