摘要： The invention relates to a device for the acoustic indication of the beats of a musical time in which the tempo at which the beats are reproduced is adjustable. According to the invention means are provided for varying the musical properties of the separate beats, e.g. the reproducing period, the volume and the pitch, said varying means being provided with N switch elements each having at least three switch settings, and a scanning element for the cyclic consecutive scanning of the N switch elements, wherein a tone is generated in a first channel during the scan period of each of the switch elements in the second switch setting of the switch element, while a tone is generated in a second channel in the third switch setting of the switch element and no tone is generated in the first switch setting of the switch element in either channel, both channels being common to the N switch elements.

摘要： A programmable electronic musical synthesizer includes a memory controlling a plurality of parameter circuits according to a selected group of stored parameter signals for producing a desired timbre of sound. A memory override system is responsive to manual operation of each of a plurality of control knobs for overriding a corresponding stored parameter signal and coupling an externally derived input signal to the associated parameter circuit. The memory override system thereby conveniently enables one or more selected parameter circuits of the synthesizer to be manually controlled by a performer while the other parameter circuits are simultaneously controlled from memory.

摘要： Apparatus for producing signals of varying volume and pitch which are functions of the magnitude and distribution respectively, of weight (or weights) placed upon a platform hinged at one corner and swingable in mutually orthogonal directions. Sensors convert the physical displacements occurring at first and second corners opposite of the platform adjacent to the hinged corner into signals for controlling the volume and pitch of an output signal. Alternatively, displacement of the platform may be controlled by the application of varying pressure by means other than full body weight, such as the operator's finger(s).The apparatus may be utilized as a unique means for producing music or musical sounds responsive to a person dancing or otherwise moving upon the platform to provide an entertainment form which is both unusual and enjoyable. The varying degree of sophistication of equipment design enables its use to encompass as diverse a range of devices as that of a rugged toy having a simplicity of design and a sensitive musical instrument capable of producing precise quality tones providing a broad range of applications within the field of entertainment.

摘要： An electronic musical instrument of a type capable of producing a musical tone corresponding to the tone pitch of a depressed key by controlling oscillation frequency of a voltage-controlled type oscillator by a pitch voltage corresponding to the tone pitch, wherein musical tone elements such as tone pitch and tone color are controlled in accordance with a control voltage which is produced for each individual key but is different from the pitch voltage.A temperature curve can be determined by controlling the tone pitch of the musical tone by this control voltage as well as by the pitch voltage. A desired temperament curve can be obtained by suitably adjusting the values of the control voltage for the respective keys. The tone color control is effected by varying the cut-off frequency of the voltage-controlled type filter in accordance with the aforementioned control voltage.
