I need help putting my own sounds into SI Drummer. I know it's not an easy feat but I'd like someone to explain it to me, either here or with a link to a video.
I believe it has something to do with converting the .WAV to a .SFZ then copying it into Cakewalk\StudioIntruments?

Some useful information about sfz: http://www.cakewalk.com/DevXchange/article.aspx?aid=108

You can use waves too. I sampled my own drum set, I then edited the files with wave lab to cut right to the hit start point. 
I found the folder where all the "flac" and "sfz"  files where stored  and dumped them there, that was it. Pretty easy actually. 

It's super spooky to here a drum machine play your kit! 

SFZ files give you more variations within the one file. I will read the link the bifliper posted as I would like to learn how to make my own sfz files too.
