Biography
Organist, musicologist and inventor Hans Luedtke developed special Oskalyd extended organs[1] and keyboards that could be used with any desired tone system. Rounded edge hexagonal shaped keys were to be arranged like honeycombs in such a way that intervals would be represented by unique vectors (i.e. a Generalized keyboard). He mentioned tunings with semi-, third-, and quartertones, methods for playing special glissandos, electronic switching between tunings or registers during performances, and he also outlined a notation system analogous to the keyboards and a direct opto-electric recording system.
