Hi Randy
The rule with setup names is that they have to be valid Belcanto, so if a word exists in the lexicon it can be used to name a setup. You can do this from the GUI save dialogue, or directly in Belcanto from the commander or instrument. The organisation tree you see in the GUI is simply broken on word boundaries, so each additional Belcanto word in a Setup name just makes another level of tree. So if you name a setup Ahdsr Filter 1 you'll get a Ahdsr level, followed by a Filter level in which will be your setup called 1.
There is also tagging allowed, which is freeform text. This is not used anywhere in EigenD but is appended into the filename the setup is stored under to help you identify them in a file manager. It also appears in the GUI when browsing.
The reason we impose the restriction of only permitting valid Belcanto as setup names is that it makes the loading and saving of setups work properly and consistently with everything else. You can for example define a talker to load or save a particular setup very easily. If setup names were freeform text this would not be possible, so we compromise by adding the tags to act as an aide memoire.
I am the 'Lexicon God' BTW, in that I'm the only one who gets to mess with it. It's due some attention very shortly as there are some unused words that have crept in and a whole load (starting with 8XXX) of new ones that need proper allocation. Allocating them well takes ages as one is supposed to be able to play commonly used phrases with ease, so it needs thought to avoid too many double or triple taps on keys, or clumsy sequences. Jim just mentioned that you have some suggestions for some more useful words - if you post them here (and anyone else please contribute too) I'll look at that and add them if they seem appropriate...
cheers
John
edit: The Lexicon in the source tree is the same as the one in the Commander BTW.
