I really want to check out their standalone/pro system. Has anyone seen the related software?
I detailed the various MultEQ Pro screens in my review. If you are asking whether or not there is a "screen shot" similar to that of the Tact that is able to be manipulated the answer is no. There are, however, eight before and after screen shots (16 total) available at the end of the calibration sequence. Audyssey's target curve is preset. The system calibrates toward that curve.
If you'll refer to my first review/interview of the Audyssey system from late 2004 here you'll find the anwer as to why:

In the late '90s Tom Holman's challenge to the then nascent Audyssey team was to make the whole system set-up "
automatic". By having the target curve fixed and hidden in the software the installer has only to focus on the appropriate-room-and-owner's-taste high frequency roll-off (or flat) response from the curves available.
In the case of the "target curve" and from my 35+ years of speaker design I believe that the Audyssey curve (which has never been exactly defined as it it part of their muli-patented system) is very, very similar to screen shot you show from your Tact system. The difference is the Audyssey guys can continue to "tweak" their curve for better performance based on information gleaned from feed back from installers.
They recently put a slight tweak (dip) into the curve at around 2000Hz. this dip was to make up for the difference in power response between a speaker system's mid-woofer(s) and tweeter(s) at that frequency. That is, 5.25" & 6.5" mid-woofers begin to beam too much as they approach 2KHz whereas tweeters have wide dispersion at this frequency. The Audyssey tweak allows the MultEQ Pro software to create a much smoother power response transition within this region.
BTW- Lest you think this type of ongoing tweaking is unusual in our industry think again. Both Dolby and DTS are continually changing (upgrading) their algorithms for their various Digital, ES, EX, IIx etc chips as their technology advances. The manufacturers just don't tell the consumers.
