Lumatone mapping for 240edo
Jump to navigation
Jump to search
Approaching the limits of the number of keys to a Lumatone and the pitch resolution of most people, is 240edo. Bryan Deister has demonstrated a mapping for this in microtonal improvisation in 240edo (2025). Following in the footsteps of Julián Carrillo, whose highest EDO (96edo) piano had just one octave, this layout achieves 1.14 octaves with no missing notes and just four repeated notes in the first octave and one more repeated note in the fractional octave at the end. In the demonstration video, the purple/pink notes are octave-reduced harmonics, except for 73/64 accidentally being left green.
