The dulcimer tab is probably the hardest thing to get in otherwise decent cheap notation programs. With quite a few of them, you can "edit" fret numbers on top of the lines, and line them up with the notes "by eye." The expedient is to use the 5 lines of a staff and consider the outer two lines the edges of the finger board.

Since the vast majority of notation programs use "frames" for all text, it does mean that you have to enter each number (digit) as a separate text block in order to be able to move it to the line where you want it. It does get tedjus.

I've encountered a couple of freeware/shareware programs that do claim to "automatically" produce tab (different programs for different instruments' tab) from the notes, but most of them were pretty marginal for producing clean notation that satisfied me. Sadly, I was so 'whelmed by them I didn't keep notes.

As noted, Sibelius lets you set the number of strings, the tuning for each string, and the location(s) of the individual frets in virtually any tab format you'd want; and automatically converts the notes to more or less usable tab; but the price (and the attitude) have kept me from making the jump to actually owning one.
