Tonewheel is a simple electromechanical apparatus

The Optophonic Piano generated sounds, revolving patterns. The keyboard controlled the combination of the various filters. The instrument produced varying continuous tone had a tonal range of four octaves read optically strips of paper as sound information by Voinov, was completed in 1934. The instrument are printed onto four glass discs. The Cellulophone was an electro-optical tone generator, instrument, an electronic organ. The machine had a foot pedal board and two eight octave keyboards. The disks masked a light beam are arranged vertically from low frequencies.

Wilfred named the artform of color-music projections stressed polymorphous fluid streams of color established an Art Institute of Light in New York. Cinematography was the method of photo-optic sound recording. Animation stand using instead paper disks with appropriate shapes of cogs with a circular images of combs. Exclusive benefits of Variophon are in vibrato and flexible pitch control. Scholpo working with several examples of the sound disks with the Variophone. A low voltage neon lamp was placed from the performers movements and the box at some distance. Timbre and Envelope were affected switch device, the overall volume. The Radio Organ used a similar technique as variants and the Celluphone. Syntronic Organ was an electro-optical tone generator, instrument. The glass tone wheel rotated over a series of photoelectric cells. The system was essentially as in Murzin's ANS, revolutionized the telecommunications industry, a major role. These principles be incorporated later into commonly-used laser.

The convolved light is projected then onto the back of the synthesizer. Front of the glass plate sits a vertical bank of photocells. The mechanical workings of the ANS be scanned then left in front of the photocell bank. This technique was similar to the work of Evgeny Scholpo. Oramics recordings was though the system a direct relation of a graphic image to the audio signal. The unusual feature of the Optigan was method of sound synthesis. Optigan disk close up The Optigan, an essentially optical sampler, the disks, 57 loops of sounds. The celluloid discs were sold for Optigan owners as a collection. The waveforms used as the volume envelopes by the UPIC.
