Abstract
1360666 Electrophonic musical instruments OPSONAR ORGAN CORP 26 Nov 1971 [11 Dec 1970] 55011/71 Heading G5S An organ incorporating an optical disc record having a plurality of circular music tracks of variable opacity defining musical tones and accompaniment rhythm patterns is provided with light means to indicate the start of a musical measure on the accompaniment tracks. A further track, for producing a tremolo effect, and volume controlling means may be provided. The optical disc 12, Fig. 2, comprises tone tracks 22 and accompaniment tracks 24, each of the accompaniment tracks defining a rhythm pattern of musical notes lasting a whole number of musical measures along the 360 degree length of track. One new musical measure on each track begins on an imaginary line 47 and the other musical measure of each track begins on line 48. A synchronizing track 50 has transparent regions 52, 54 located on the lines 47, 48 and one end 58 of a light pipe 56 located above the synchronizing track receives light through the transparent regions from the light source 30. The other end 26 of the light source 56 is located on the panel of the organ such that the player sees a flashing light at the beginning of each musical measure. A tremolo effect is produced by means of a track 60, Fig. 3, which contains uniformly spaced transparent and opaque regions. A photo-cell 62, the resistance of which is dependent upon the intensity of incident light, is located to receive light passing through this tremolo track. The output from the photodetector 32 may be connected to the amplifier and loud-speaker via the photo-cell 62 to produce a tremolo effect or it may by-pass the photo-cell 62 by suitable arrangement of the switch 28. In order to control the volume while playing a swell-pedal 70 is used which controls the intensity of light incident upon a photo-cell 76 the resistance of the photo-cell being dependent upon the intensity of the incident light. The range of the volume control is initially set by means of a manual control 78 and the photocell 76 is connected in parallel with 78 to vary the volume within this preset range.
