Sean, I've spent the last little while looking at TAB Freeware and Shareware. I'm sure that you'll get lots of other responses, but for my benefit are you talking about mountain dulcimer? If so, and pardon my lack of intimate knowledge, what tuning is typically used on the non drone strings? There is MD TAB at the Alternative DT site, but I'd need to check the source of the program that produces it. Regards, John
