Hi I currently own Sonar Professional and am looking to make an EDM/Electropop song. However, I was hoping to add white noise sweeps and riser effects to my song and wondered if any one knows if I can achieve this within Sonar? Any help would be greatly appreciated!

To me it all depends on what synth plugins you have.  I have been experimenting with EDM type stuff lately, and I tried a few other DAWs and came back to SONAR as the main DAW.  It comes down to the synths you have and the DAW to give you the workflow you are comfortable with.
 
FWIW, I recently picked up the AIR total bundle and it includes theRiser which specializes in those types of sounds.  A lot of synths have presets to get you started with that type of thing as well.

This should get it done
 
I got this with the AIR collection.  It does just one job, and this is it!

I have Reason 9 as well as SONAR and it is very popular with the EDM crowd, FWIW.

iZotope's Stutter Edit is a nice tool for doing a lot of EDM processing and effects. The name is a bit of a misnomer, since the stutter feature is only one of a gambit of features that it has. In fact, most presets have the stutter enabled, so simply turning that off lets you delve into it more deeply (the stutter can be a big distraction TBH). Each parameter exposed can be tailored for sweeps and processing, and may be an easier alternative to doing it within SONAR - static sweeps as samples are simpler than dynamic ones, unless you are savvy with synths (although that option is viable, it is not "quick and dirty").
 
iZotope does 10-day fully functional trials, so is worth seeing. It is also 80% off at the moment.

There's also some free sample packs you can download.

            Thanks for the info on these neat plugs and the special pricing! 

I know musicians making EDM without any DAW. They use an AKAI MPC and some hardware-synthesizers and record them to reel tapes. Using hardware equalizers and limiter. Then they send them to us to digitaze the tapes to make a CD-Master.
We ourselves use Sonar for EDM since 1995 and we use a lot of Hardware- and VST-Synthesizers.
It's a question which Synthesizers (VST, Hardware) you are using - not a question of SONAR.
