Kinda odd question

[Taiyed]

I was wondering about this and maybe someone could get an answer for me. Here's the scenario: I use Sonar XL. I loop my guitar parts. Let's say I record one loop and save it. Then I record another loop immeadietly after (which would be the part that follows the previous loop's part in the song), using the same everything and save that. I import loop 1 to track 1 and then copy and paste it to track 2 .004 seconds later. I pan track 1 90% left and track 2 90% right. Then I import loop 2 to track 3 so the end of the above tracks will transition into the start of loop 2 and copy and paste it to track 4 .004 seconds later. I pan track 3 90% left and track 4 90% right. Tracks 1, 2, 3 and 4 are all at the same volume. Now if all of this is so, then shouldn't the guitar parts pretty much sound the same when part 1 transitions into part 2? But, instead on my computer and on my recordings you can clearly differentiate between the guitar parts because they have a distinctly different sound! To me, this makes no sense. I was thinking perhaps it is my sound card? I have an SM57 mic with fine cables and a fine guitar rig. So is Sonar maybe reading the data differently when it's copied and then pasted? Because i noticed the parts sound pretty much sounded the same and transition well when they are in mono. But it seems once i seperate the them, pan them opposite directions and move the one slightly forward, that's when the trouble begins. If anyone knows why this is, it would be great to know. Thanks.

Wow, what a strange way of working.

When you record the original loops, are they on other tracks in the same project? When you copy and paste them into other tracks, are you then not muting or archiving the original loop clips? This could cause some comb filtering effects which might range from a phasy, nasal quality to a noticeable dimunition of the sound where the loop overlaps with its copy.

well i forgot to mention that i record the loops in a seperate program and then import them into sonar...why i don't know.

Well, then I have not the foggiest idea of what you are doing that might cause this. I can't understand the working method you are using either. I suspect it has something to do with that, but it beats the hell out of me.

Wouldn't that create a insanely weird flanging effect?

And I need to ask: What good will come of this method?
