Hoo boy....  thanks much for the feedback,  I do appreciate it, but it seems some of you are not familiar with what I'm referring to, or I've just totally lost my marbles.  So... I'll try be very specific. My system is Win 7 Pro 64, Sonar X3 Studio, Scarlet 2i2, ASIO drivers. Just moved to X3 Studio. Was on 8.3 P before; same drivers, same interface as before. 
This is just for the record...  just wanted to ask why they took away this seemingly great feature:
In Producer 8.3 there is, in the "Audio Options - ASIO" dialog box, something called " RECORD LATENCY ADJUSTMENT (samples)". It shows up on the lower left hand corner of the screen, and is labelled as "manual offset", and has a totally variable +/- adjustment range, in SAMPLES.  (notice that this is NOT buffer length, and it is adjustable plus OR minus, in SAMPLES). On the lower right portion of the screen is the "USE ASIO REPORTED LATENCY" (in my case it is "1022").   
(The system determined the latency to be 1022.  Then you could manually offset that to whatever you like. )
So, this feature is gone on X3 Studio. It's just not there. I know it's all moot at this point, but all that is left to me is an adjustment for buffer length, from 2mS to 10mS. 
I don't mean to be an upstart here or anything, just a newb curious about stuff....   but THIS SPECIFIC feature is just not available on my X3 Studio screen.  Is it available on yours ?

I certainly exactly where steve said it was for me?? Might be the 2i2 driver is different than my 6i6 which has mix control.  as said by Mac. But as far as I can tell the manual offset is a Sonar thing.
I'll fire up my Tascam system tonight and double check. I just installed W8.1 so might be a while before I got everything running agian on that system.
 
May I ask if the loopback is showing your timing is off? Mine is bang on.

Nope, no mix control on the 2i2, only a buffer length, from 2mS to 10 mS.  Yes, the manual offset must be a Sonar thing, as I'm using the same drivers and interface as I did on 8.3. Currently it appears my latency shows up as approx. 7 samples or about 1 mSec...   if I read the scales properly.  Is this good ?

Would a picture help? The adjustment is now made at the bottom of this page. This illustration from  http://www.cakewalk.com/Documentation?product=SONAR%20X3&language=3&help=Dialogs2.056.html
 shows a driver mode other than ASIO. If ASIO driver mode was set, there would be an additional check box to "Use ASIO Reported Lantency" and an entry field for the latency.

Fantastic !   You totally got it !  BUT !   I don't have that screen available to me for some reason.  When I go to "EDIT, PREFERENCES"  Under the AUDIO heading I only see Devices, Driver Settings, and Playback and Recording.  I dont' get the last 3 selections Audio Profiles, Configuration File or Sync and Caching.  I see they are highlited BLUE on the screenshot... what does that mean ? 

It is an Advanced feature. Make sure to select the Advanced radio button at the bottom of the Preferences dialog (just like the picture).

Right on, Scook !  The case is solve-ed, Chief Inspector !  Thanks for your patience, guys ! Whew. 
 
Well that's what I get for being a newbie...  couldn't find the screen !    
 
All is good now, except for some reason the AUDIO PROFILES selection doesn't come up for me, even in the "Advanced" screen. 

It is not displayed for ASIO driver mode.

Ah...   then all is good.   Thanks much !  
 
EDIT:   FYI and FWIW,  I went ahead and did another hardwire loopback test, and found the source and recorded tracks were a bit off.  Then, with the system ASIO reported latency at 2486, and a new setting of -3 on the manual offset, the source and loopback   tracks are bang on.  Sweet !  thanks again for your patience and help !

You are welcome. Glad you got it figured out.

So I was pretty much on the ball then. OK so there is no mix control with your interface. If you had a Scarlett 18i20 for instance then you would have Mix Control which would give you an ASIO buffer size setting to play with.
