Incidentally. I submitted a feature request once upon a time, asking the Bakers to add a function that automatically throws away that last partial take when it's less then some user-configurable length.

My other DAW has this option and it is GREAT.
 
OTOH, other than the clip litter, comping is very cool in Sonar.

Perhaps I'm misunderstanding what you're trying to do but wouldn't it be easier to set up an auto punch region within a loop? That way you start recording and do as many takes as you want without the hassle.

I do this too, but sometimes it really breaks up the mojo depending on what is there before and after the target punch point(s).  I'm really trying to get used to this.
 
Overall, I personally find the whole loop recording thru final comp a bit fiddly and awkward.  I'm continuing to use it though, hoping it will get smoother as I get more used to it.

"I think one of us is not understanding the other correctly. In no way, during comp recording, will any new take be "splattered" over old takes."
 
Uh, yes it does, does splatter, yep, uh huh. 
 

 
 

Those bits, as I already said, aren't your last take. They still are the earlier takes, simply split by the length of your last partial to make the final comp.

As was already pointed out, you could "heal" the whole thing by deleting the lane with the partial and the using the comp tool to swipe one complete take.

I don't see anything wrong with this behavior, it fits with the comp recording paradigm. A function that would automatically delete takes below a certain length might be helpful, but could also be confusing.

I either still don't understand why this is giving you trouble or you don't understand what's really happening and how to fix it easily.

Yup, it's just a split that can be moved out of the way or will disappear if you delete that top take lane/clip.
 
It thinks you are doing a punch in for that section so it automatically creates the split so you can compare and comp just that section across all your takes. It takes some getting used to but it makes sense and is rather helpful once you figure it out.
 
The comping feature is something you really have to study up on to fully understand what the heck it's doing. I found it unuseable until I sat down and spent a half hour really figuring it out (until then I stuck with Sound On Sound and did things the old way). I still have to refer to the little cheat sheet I made sometimes even though I've been using comping mode pretty extensively.
 
As I said upthread... if a previous take is being partially covered up by lead in/lead out silence (which is guaranteed to happen when doing punch ins in Comp mode) you just have to readjust the split to where it is supposed to be or, now that I'm looking at what you did, delete the unwanted/silent clip.
 
This is also why I never do the Loop/Punch record thing. I do a TON of takes and I immediately know when something is garbage. I don't even have to look at my keyboard anymore to tap out a quick Spacebar (to stop), Ctrl + Z (delete last take), R (restart recording from punch point).
 
Seriously I've been tracking a lot lately and because when I'm getting into things I tend to close my eyes. I catch myself doing that binding sequence without even opening them which is starnge because I don't even have my hands over the keys (they are on my guitar).
 
Of course occasionaly I miss and wonder what the heck I just did (usually fit to screen or something relatively harmless) which is why I have to remember to open my eyes... lulz.

OK, now I see/understand.
 
You delete the partial clip, and starting outside the next clip-take swipe all the way thru with the mouse icon representing the comping-tool icon.
 
That said, you can understand my frustration after deleting each and every one of those things one at a time.

That would be a really time consuming and annoyance inducing way to deal with it, yes ;)

Like Beepster, the new speed comping in X3 confused the hell out of me in the beginning. Watching a YouTube tutorial for ten minutes has been my best investment in X3 so far. It's really quite elegant once you get used to it.
