When I left for Paris after my undergraduate degree in Australia, I brought the beginnings of a guitar synthesizer along to develop. My modest progress at that time to the challenge was a hexaphonic optical pickup and the unfortunate discovery that Phase Lock Loop (PLL) chips of the day would not reliably track any slightly interesting guitar playing I could come up with. Forty years later the situation is not much better.
