'Spectral Transformations' | polychromatic 55

A polychromatic composition with the prototype Lumatone keyboard. 55 notes per octave. The Lumatone can implement custom key colors, MIDI note/channel numbers, and tuning layouts. Scheduled for production in late 2020. This is the first keyboard controller that I've used which does not have an embedded 12 note chromatic (black note) pattern. Here, I'm applying the polychromatic system to pitches 'A' through 'G' and using pitch-color to distinguish varying shades of flat/sharp. This simplifies the system further and also eliminates the need for key signatures or microtonal pitch modifier symbols (accidentals).
