Lumiano Diagram

As previously described, the Lumiano is a fully-functional 88-key upright piano. It is tuned to (more-or-less) equal temperment; due to the inclusion of all the added electronics, perfect intonation cannot be guaranteed. There is also a functioning sustain pedal (right pedal) which can also be used in musical performances; however, the una-corda and sustenuto pedals (left and center pedals) are less reliable.

All of the piano keys are mapped onto the central light board of the Lumiano. The note "D" in all octaves corresponds to the central column; the other notes are mapped as shown above on the annotated diagram.

The rows are mapped to the different octaves, so the top-most lights (octave range 6) on the grid represent the highest octave of the piano. (The lowest notes of the piano are in octave range -1.) Remember that C3 = middle C, and you should get an idea of how the lights are mapped out.

The lights are triggered whenever the key is pressed down (it need not be pressed all the way down), so it is possible to press a key down very gently and trigger a light without generating much sound.

In addition to the central light grid, there are also 6 bottom lights and 6 pinwheels that make up the Lumiano's visual component. These "special" bottom lights and pinwheels can be plugged into to any key, so certain keys can have both a grid light as well as a special effect on it. (Grid lights are permanently hard-wired and cannot be adjusted.) Thus, composers should feel free to specify what specific piano keys they want associated with what special elements (but do allow time between pieces to make these adjustments.)
