It's really about extended trombone techniques. Any kind of tuning on a trombone, including adaptive tuning, would really just depend on the ear of the trombonist. So the place to find out about that would be to understand adaptive tuning in relation to just intonation as a theoretical problem, followed by just intonation ear training. Off the top of my head, I don't know who has such a program, but it should be genralizable for most instruments. You can also make your own examples on a computer, using, for example, Csound. I have a lot of information on this is my course notes, http://www.cs.ust.hk/~layers/comp342/comp342.html. (some of the links will be hooked up later in the semester; you can view the page source code to find the files now). Best, Lydia Ayers
