But these ideas are not new. Right, the Guitorgan made in the mid 1960's did this, each string wired separately and the frets wired, compelting the circuit. I think it was Yamaha that made a synth guitar that didn't use actual guitar strings, but some synthetic material and they were all the same diameter. I have an old IVL 7000 MKII, that allows transposition for each string. You can use small diameter strings all the way across then use the transpose function to be in the correct octave. HW
