[RWP] how to do audio quantizing with reaper?

[hadi]

Hello,

I'm trying to record a drum with my workstation.  i output the 
workstation's audio to reaper.
I'm not a good drum player, thus my timings are not 100% right.
Is there a way to do audio quantizing in reaper, so my drum and rhythms 
become accurate?
I did a google search, and i found this.

so slicing and cutting sounds like that it would require eye sight to 
match clips  with each other visually?
I would appreciate it if you help me out with this.

Cheers,
Hadi
