Soundwise took a David Glenn multi-track recording and built a SONAR PC "Console" using tape and console on every track and bus. 
 
I did a mixdown of that project.
 
Then I turned off all FXs (tape and console) and then did a bus export. I imported those buses into Mixbus 32C V3 tracks. I routed those tracks to each of its own Mixbus which were then summed into the Mixbus Master bus. I left each track and bus at unity gain.
 
The only thing I did was level match the final mixdowns to insure that if you put them in non fx'd SONAR project you can use solo exclusive to A/B them and not be distracted by sudden/drastic level changes.
 
If you PM me I will give you links to the files. Anyone can request them by 5:00PM PST Wed 3 May 2017. I will give all requesters until Saturday 6 May 2017 Midnight PST to post their comments on (either) which one they liked better or which was SONAR and which was Mixbus. On Sunday morning 7 May 2017 when I wake up I will update this OP with the "answer" as to which was which.
 
Important to note both versions are devoid of any extra FXs such as compression, eq & reverb. IOW it's not a mix but a comparison of the two "console" versions attempting to be close to equal as possible.
 
And now for the answer:
 
B=Sonar
A=Mixbus
 

Thank you guys for doing that. This is very interesting. Really looking forward to the results.

What??!!?? No PM request to participate?

Lest ye who try to suss out which file is which by the name, remember this....

I'm getting excited to hear from those that got the A/B files and which one they think is the Mixbus version or simply which one they liked better.

I looped 36 seconds in to 1:03 in.
 
There is a very real difference on my system.
 
The part at 36 seconds: at first it appeared that A was slightly lower in volume, but it sounds more like there is a muffled sound to it - like the old "blanket over a speaker". Interesting that the guitar in the right speaker sounds the same for both A and B. The snare seems to be a bit loader in B. Same with the vocals - like there is a bit of a bump in the mid-range in the center channel.
 
When I get to the harder part at about 44 seconds the difference is a bit more subtle, but it's still there.
 
The only way I can describe it is there appears to be a bit of a mid-range hump in the center channel on B, but the amount of bump seems to be volume dependent and therefore less noticeable when there is more signal.
 
PS: Thanks for doing these Ed! :)

I can't quite glean from you response as to:
 
a) which you think is the Mixbus version
or
b) which did you prefer
 
 
WRT to prefer, it's not a vote on which is better, simply what you prefer.

why you so pushy?

smallstonefan
why you so pushy?

:P
 
At this point I have no idea what's the mixbus version I just know they are different. As for preference, if I had to choose I would choose B, because the midrange pops more, but at the same time I feel that you lose the vocals behind that pop...
 
Since this seems more affected I would guess that mixbus is B.
