If the diagrams don't appear on the page, download the pdf. Gorgeous--it's one thing to read about these temperaments and another to see the color charts he's created:

And the timeline on page one, showing the popularity of the tunings and the composers lives, is a nice touch.
I'm a complete novice when it comes to all the tuning terminology but it would be fun to hear what some of those sound like (well, ones that pianoteq doesn't already have, of course.)
(Oops--I see from your post in another thread that you've already found most of this, but I'll leave the information here.)
Well, we can load Scala files from the Scale box on the Tuning pane. Scala has many of these tunings and more. The general site for Scala is:
http://www.huygens-fokker.org/scala/
You don't have to have the program to use files that have been created by it. The download for the several hundred files is at:
http://www.huygens-fokker.org/docs/scales.zip
Once you unzip the file, you click on Pteq's Scale box and then navigate to their folder. (And lose many years trying out these tunings...)
Be aware that these files were created and named by many different people, so you may want to go to (or download) this description of the files and do a Ctl-F search for specific words:

For example, I'm trying to learn more about a specific Victorian tuning right now, but only one file has the name "Victorian." However, doing a search led me to file descriptions that indicate several are meant as variations of the scale. (But I'm not sure that any of them are giving me the sound that I've been hearing...)
