Though you didn't raise the question with me directly, I do wish to point out a difference here, tuneit.
When I mentioned DAde (talking about myself, not Randy), it's a tuning, not a chord (though, yes, it is technically an Asus4 or Dsus2 chord if you choose to utilize it as such, which I have done in songs when needed/desired); but still, it's a tuning. I use this tuning because of the comfortable chord shapes that can be used, as well as chordal relationships (near each other, not up and down the fretboard to find the next chord in a typical modern song).
That is how I personally came about the tuning I use; I took quite some time tinkering with different tunings, looking at chord shapes/fretboard relationships of common chord progressions found in popular music, until I decided on this one as the best compromise, for me, especially in light of the fact, as already mentioned, that I wanted to keep part of the heritage of the instrument- a base modal tuning (in this case Mixolydian), yet augmented for my needs.
Keep in mind, as well, that I am talking about chordal shapes/relationships on a chromatic fretboard with this tuning, not a diatonic setup- I know Randy has mentioned having chromatic as well as fretless setups, but I don't know if he is talking about using these tunings on all his setups or just on a diatonic or 'extra-fretted' diatonic (1+, etc., but shy of full chromatic) setup.
I am assuming you are asking that question from that angle, that of a diatonic dulcimer utilizing a chromatic tuning, but I am talking of using this tuning for chromatic setups (fretboards, not tunings), hence my wishing to clear up my position as to your question/remark- unless I'm wrong as to the intent of this overall forum, which has been known to happen

.(not specifically this topic, though, especially since the more I look at it's title I can see now why you raised the flag). I only play a chromatic fretboard, so I don't look at whether a tuning is chromatic or not, as I don't need to worry about that, just the relation of the notes to each other.
I'm sure Steve or one of the others will correct my incorrect assumption about this forum, and head me along the right path (or a different topic, or out the door!) soon.
As far as the tunes go, I don't know or play the traditional tunes (nothing against them, I just didn't have those tunes at my disposal when I was learning to play, so I didn't learn them); I play my own/modern stuff mostly (including blues, country, jazz, r&b, big band music, bluegrass, reggae, rock, South African music; for example- Lady Gaga, Brad Paisley, Black Eyed Peas, The Band, The Dead Kennedys, Flatt & Scruggs, Nat King Cole, Earl Klugh, Son House, Boyz II Men, Grateful Dead, Marvin Gaye, B.B. King, Taylor Swift, Hendrix, Sade, Nine Inch Nails, Rihanna, Metallica, Jack Johnson, Chris Ledoux, Tony Bennett, Allison Krauss, Bob Marley, Old Crow Medicine Show, Sinatra, James Taylor, whatever; I like all kinds of music, I'm all over the place with what I will play; too much likes to list here, etc. and so on...), with some occasional Irish or early western music (Renaissance or earlier pieces; I do like early lute pieces), and some guchin (the ancient chinese zither, aka ch'in) pieces (the really old songs are around 3,000 years old);, I really can't comment on the more 'traditional' diatonic tunes, though I have heard them, since I don't really know them (like them, yes; enjoy hearing them, yes; just didn't learn the usual repertoire most festival-going dulcimer players seem to learn, and therefore haven't played them as much/at all).
It seems that what the chromatic does do is allow freely using a capo to allow the guitar's trick of retaining the same fingerings (or using fewer variations) and the same open notes for the chords, while changing keys.
I myself don't utilize a capo, though I do agree that, as with any chromatic instrument, this can be seen as an advantage over a diatonic setup if it is needed for ease of playing a song.
Now we have to make a distinction between exploiting a chromatic instrument to play diatonic music and actually playing chromatic music...exploring the non-traditional repertoire, blues and other jazz-based music in particular. I think each might have a different following.
Personally, I am all for capoing versus retuning, certainly as a starting position. The idea of a chromatic set of frets appeals to me.
I understand what you are getting at here, regarding accidentals needed in songs, and that there might be different crowds for each type, but for my tuning, I find I don't need to retune or reach for a capo- but then again I haven't really tried to either. I just look at the chords/notes needed for a song, any song, and play 'em

.
That is the other reason I labored so much by myself to find a tuning that was flexible enough for what I play, so that I would not have to retune, especially as my playing has been with players of other instruments, not dulcimer players, and they (especially the jazz/classical players, and the guys I played with in the south african group) would not wait long for any retuning when jamming or rehearsing, or when you have multiple key changes within a song.
So to sum it up simply (which I'm sure you have wished I would have done in the first place, by now

), I utilize the tuning on a chromatic setup, not as a chromatic tuning on a diatonic setup, and have found it very flexible for modern music.
