Even though I use SoftSynths & I don't record drums, I tried out Drum Replacer on a finished audio track by The Pretenders. It worked amazingly well and quite easy to use. I had no problem isolating the various drum hits with the filters.
   Good job Cakewalk!  
 
   Why does my spell-checker tell me I am misspelling  "replacer" ?

I believe that "replacer" is not a "real" word (then again, English is not my native language)

How do you get the different replace elements to different midi notes?

Btw, I like it too.

There is a little MIDI note spot on the lower right corner of each of the DR filter/dynamics elements.

I believe that you have to drag it to a MIDI track, if that was your question. 
Best of luck.

When I do, all the lanes get the same note. I think enabling the different lanes, one at a time might be the trick.

Are you setting the MIDI note (illustration from http://www.cakewalk.com/Documentation?product=SONAR&language=3&help=Region_FX.07.html )

I had no idea it could be used on a mixed track with more than just drums. I'll have to give it a try. And yes, I agree...it's pretty awesome.
 

Yep, hit on that idea myself earlier. It's pretty good for extracting MIDI beat data from songs you like. Works better on sparse and spiky material, of course; the Pretenders have exactly the right performance and production for this trick. I tried it on Around The World In A Day by Prince, where it worked really well.

I'll tell you what, this is a really superb bit of tech, but more strikingly, perhaps, I think it's the best bit of user-interface and workflow design Cakewalk have ever done. Get the team who did this to make an AudioSnap 3 and I'll found a polytheistic religion devoted to their worship.
