staff view suggestion

Trying another way in my years of not being able to get satisfactory drum results (too tedious, too complicated, etc,etc)....I figured if I looked at some pre-recorded drum tracks , written down on staff, I could get a better understanding of drumtrack creation, and, have a powerful way of writing my own drum parts...So I'm starting with a drumtrack from songster.com, written on staff...as I try to one by one draw in the kick/snare/hihat basics in Sonar X3, using addictive drums as the source, I am noticing that for some odd reason, click and dragging a note on a single staff line or space results in more than one sound!...I have to 'scroll thru' the 2 or 3 sounds to get one what I want...how do I edit so that each line/space has a single sound?
 
Also, and mainly, I have noticed that I VERY frequently goof where I put the note or it draws one where I didn't want, or draws one when I didn't want, using the start (supposedly 'smart' lol) editing icon....when I go to erase the goofs, I have to go down to the task bar and select the eraser....shouldn't there be a much quicker means of erasing? Like, shouldn't I be able to right click on the draw tool and erase? Can you make this an option? Thanks. :)

Ok nevermind on the 2nd question...lol, I didn't see that you have to set the note resolution under the select icons...thought it was set in the 'snap' section ..that did it...but I still would like the erase to be a right click option!

Hi Guitz. I understand looking at examples to learn drum programming, and I presume you are talking about drum maps when you say that previous attempts were too tedious/complicated. Why not open your examples in Piano Roll View? It is far more flexible and easier to edit in than staff view.

 
I hadn't thought of that...I just figured that if there were any fast or complex fills, etc, that drawing them in the staff view would be easisest, because they would snap to the correct timing and I could visually compare it to the original....the REAL easiest way, is if I could export the drum score and import it into sonar but I don't think I can export it in a way that SONAR could read/open.

PROMIDI, I know we used to use CAL for this, but do you have an example of a reasonably-priced effect for what you mentioned,  "humanizing MIDI FX"?  Thanks.
