I had very weak low end on a Kick Drum that I was stuck with so I enhanced it by side-chaining a 50Hz sine wave generator.  I thought the PC4K Gate worked great.  Very pleased.   However, when I put my headphones on and didn't realize my volume was cranked, I could hear the low hum from the wave generator leaking out of the  PC4K Gate.  Very low.  So low that most may let it slide.  Ironically, the song that I was working on is titled, "Don't Do It (Just Let It Go)."  
 
I fooled with the PC4K and even setup a new project and tried it again.  Hum. 
 
I plugged in the Sonitus Gate.  Perfect!  I use the Sonitus plugs a lot and glad to have them.  I keep going back.
 
Maybe the Bakers can update them to 64bit or whatever.  They are solid performers.

They are 64 bit, the only thing old about them is the GUI. I still use them a lot for things when not using the Pro Channel.
 

The versions included with Sonar are DX plugins and are 64 bit. You can purchase the bundle as a seperate product and that includes a VST 2 version also 64 bit I th no but the GUI is identical.

The Sonitus suite bundled with SONAR are both 32 and 64bit DirectX effects. Unless the store copy is incorrect, the VST version for sale separately is 32bit only http://www.store.cakewalk...ductid=36-CWSF3.31-10E

Thanks for correction. I tried to write "64 bit I think" but fat fingers typed something illegible.
