This is a question as well as an idea. Could the Chordmaster (the software for the palm handheld, as well as the little gizmo) be used for alternate tunings (open tunings, broken tunings and others)? And could it also be used then for instruments with fewer strings ('ukuleles, mandolins - I know they're eight strings, but only tuned to four different notes)?
It's a lot to ask, but since I rarely play in standard tuning, and only play guitar have the time I make music on fretted instruments, it would make all the difference.
