That wont do anything as its 2 different things. The 64bit engine has nothing to do with your 64bit windows. You can run the 64bit engine is a 32bit pc system. One has nothing to do with another.


There 2 entirely different things and they are unrelated

I told you wrong.  Go to preferences>audio>playback and recording to change the driver mode to ASIO.  Then you can access the ASIO panel on the driver settings page in preferences.

That fixed it.  But I don't understand why.  Why can't I send the midi outputs out one port and the audio out another?  I was able to get away with this under Home Studio 4 (after a lot of struggling.)
 
I'm still in the dark on ASIO.  When I get to Driver Settings, I see no mention of ASIO.  And what I do see is rather confusing.  I've changed my Audio Driver Bit Depth from 16 to 24 since that's what the US-144MKII outputs.

Dim solo gain makes little sense to me, I've left that at -12dB.
 
Sampling rate I've left at 44100 though the Tascam does up to 96KHz. 
 
The mixing latency parameters are set at buffers = 2, buffer size = 1364 samples, 30.9msec.  I'm hesitant to goof around with these, as I'm not sure how I'd test whether I've had improvements or not.
 
For the record, the wave profiler showed me:

 So, what's my point?  This stuff is pretty technical and somewhat confusing.  Discussing it here is proving to be helpful.
 
Thanks much to those who have spent the time to respond.

Haven't tried to update the driver.  While wrapped around another axel I thought I ought to do that, never got back to it.  Thanx for the reminder. 
 

Oh boy.  I never would have realized that.  What's a 24-bit engine all about then.  Or doesn't it really matter?
 

OK.  I discovered that a while ago.  Mine was set to WDM/KS.  I changed it to ASIO.  I haven't noticed any difference.  The original problem was fixed when I stopped using the on-board sound card for audio.
 
I'll have to find the description of these options.  I have no idea what they stand for.
 
Thanks.

The original problem was fixed when I stopped using the on-board sound card for audio. 

As that is what is causing the problem. You cant use the Tascam interface/sound card and your onboard sound card at the same time for recording. The clocking will be screwed up and the track being out of sync is due to the clocking being screwed up.  

Driver modes and bit depth will not solve you or help you with this isssue. Just use the Tascam for recording.

It's just for what I mentioned: Internal calculation. A VST with that feature, for example, can manipulate the signal in 64-bit quality even when it receives the signal in 24 bits. SONAR can do the same, manipulate the signal internally in 64-bit quality, even when operating in 32 bit environment.

When I saw you ran the wave profiler I knew you were in the wrong mode, ASIO mode does not run that. That mode works but is not ideal as you cannot access the Tascam ASIO control panel. 
Use ASIO mode, make sure you have the latest drivers downloaded from Tascam Support. Make sure they are listed as for W7 64 bit. 

Use the Tascam control panel to set your clock rate and latency. 
Make sure there is no sign of the real tech in any of the Sonar audio option dialog.
