Title: K.C.S.L.S.--KEYBOARD-CONTROLLED SOUND/LIGHT SYNCHRONIZER 1978.00 / Dimensions: 50 cm x 50 cm x 40 cm. Handmade electronic device intended as a prototype for a full-scale version. The purpose of this device was to produce a visual analog of music performed on a keyboard in real time, that would reveal the mathematical structure of music (pitch and rhythm). Such a device, it was thought at the time of construction, would provide hearing-impaired persons a way of appreciating the underlying mathematical structure of music, as well as to enjoy the experience of performing it on a keyboard instrument. Such a device would also enhance the listening experience of people with normal hearing ability. The conversion of the keyboard input to a visual display is done entirely by TTL logic hardware (shift registers) and makes no use of computer software. In recent years (beginning around 2010, I estimate), skillful computer programmers have written very sophisticated and effective programs that realize the idea of a visual analog of music to a degree far beyond the original vision which motivated my construction of the KCSLS. One need merely input the name of a musical composition into the www.youtube.com search box to access both keyboard and orchestral examples of such.
While these are brilliantly executed and mesmerising to watch (and listen to), they can only be passively experienced. A full-scale version KCSLS would enable any person with some degree of pianistic ability to "play it," as s/he would a piano, and both sound and light would be the output. I have yet to see any commercially available version of such a device as of this writing, 9/2/2017. H. Slovic
