I'm grateful that CW found a quick workaround for those having problems with the X3C update and the Console Emulator buzz.  However, I have questions about turning off the 64 bit double precision engine.  What will be missed by turning it off?  Will it affect recording?  What about mixing?  I often switch back and forth between the two, and having this extra step in order to use the CE seems like a bit much unless there is no audible difference by doing so.  Will there be a patch for this anytime soon?  I want to stay up to date, but not until everything works at least as well as X3b, which is giving me no problems at all.  If anybody can shed light on this, I'd be grateful.

Ths short story is if you got the horse power to use it (and most people these days do), then use it. You benefit from it when the math is done inside Sonar.

So, I'm guessing, the 64 bit double precision engine helps 64 bit plug ins run more smoothly?  I don't necessarily consider turning the 64 bit engine off a viable workaround if you have to take one step backwards to take one step forward.  Is my logic faulty, or am I just being too picky?  I suspect many have the same reservations.  I would really love it if someone from CW chimed in here.

no it's not related to 32 bit versus 64 bit plug ins at all. It relates to the playback or recording bit depth of the project. Be default, SONAR wave files are 32 bit floating point - but you can save as a 24 bit, or as a 16 bit wave file, with or without dithering. As Grem points out, using a double precision "engine" forces SONAR to playback or record at a level of precision that exceeds the 32 bit precision of the native (SONAR) wave format. I can't hear the difference personally, and my recording chain for audio is limited to 24 bit (on a good day with a tail wind) so I normally have the 64 bit DP engine off here anyway - not a recommendation, just my personal preferences given that I have an old CPU and can't afford the overhead.
 

Back when CW first came up with the 64bit internal engine, there was much talk/discussion/down right arguing about the benefits/lack of 64bit internally. And at the time I read more about the subject than I ever thought I needed. But it was very interesting.
 
The reason I am reluctant to explain in detail is because of my limited knowledge. Someone with better explaining skills than I have will jump in. Those guys who know the deal are really eager to teach others.
 
And when they see someone stumbling to explain, they usually come in and clear things up.  :)

It's a valid work around, nothing should be broken when turning this off, you may experience a sudden loss of self esteem knowing it's not going quite up to 11. Also when you know it will probably be fixed in a month or so (I can't give estimates though, I'm not Cake) then there really is nothing much to complain about, not that you are actually complaining, far from it :) In the meantime I recommend cucumbers down underpants....

LOL  That usually ends up as a Greek salad.

Using the 64bit engine changes the level of the rounding errors in Sonar's mix engine from a pin dropping next door to a pin dropping on the moon.

Lynn, have you tried just turning the 64-bit engine off and listening?
 
Or, if you want to get scientific about it, export the full mix with and without the 64-bit engine enabled and do a blind ABX test.

Dave, I'm going to download x3c again and give this a whirl.  I don't have golden ears, so I don't expect to hear any difference.  I'm sure CW will have this fixed in no time.
