The software can cycle through any set of frequencies I give it. The challenge is making it intuitive to switch between them. Someone suggested a mode switch to go between different tunings, maybe even a mode that does every semitone.
That said, if you'd put it to tune the upper D string, it will tune to the overtone of the drop-D string without much trouble.
I have a whooping 3 hand-soldered tuners in stock now, once I get those in the hands of real users, I might do a second iteration and look for manufacturing.
