Abstract: Provided is a tone control device coupled to a musical instrument including a plurality of pipes capable of generating tones with differing pitches for keys, wherein the pipes are arranged in rows, comprising: a tone generation device that generates tone; a pipe designation device that designates a specified pipe among the pipes installed; and a control device that causes the tone generation device to generate a substituting tone corresponding to the specified pipe when a depressed key comprising one of the keys corresponds to the specified pipe designated by the pipe designation device, and the specified pipe is a pipe belonging to one of the rows of pipes designated as a tone generation subject for the depressed key.

Abstract: A musical instrument or multimedia input device is disclosed. User input is by hitting or striking water in order to produce an at least partially transient acoustic disturbance, vibrations, or change in the water. In one embodiment rigid pipes of various lengths or diameters emit fluid for being struck by a user at an open end of each pipe. The other end of each pipe is connected to an elastic tubing or other elastic medium, such as a diaphragm or bulb, resulting in a hydraulic resonator. In another embodiment the resonators are formed from variously sized bottles or flasks encased in cement, except for the mouths of the bottles. Each hydraulic resonator may be fitted with a sensor that senses the vibrations in the water and amplifies the vibrations into a sound reproduction system, such as an entirely acoustic impedance matcher or an electrical amplification system.

Abstract: The present invention relates to a set of organ pipes including at least 54 pipes, characterized in that said set has a variation in the richness of the harmonics generated by said pipes during use, and in that the ratio of the intensity of the first harmonic to the intensity of the fundamental is at a maximum at a frequency between 150 and 500 Hz, preferably between 200 and 300 Hz, wherein said maximum is different by at least 20 dB with respect to the ratio of the intensity of the first harmonic to the fundamental of the pipe producing the lowest frequency note.

Abstract: The invention relates to a method for the operation of a pipe organ, with at least one of the valves being provided as a valve actuated in multiple ways which can be controlled to open at least on the basis of two different note demands. In accordance with the invention, on a note demand on a valve actuated in multiple ways which is already open due to another note demand, the valve actuated in multiple ways is closed for an interruption time period and then opened again. The invention further relates to a method for the operation of a pipe organ, wherein information input at the console is transmitted via a data bus to remote receiver units which are connected to valves and/or stop pallets for their control, with the receiver units determining individually from the information transmitted whether, and if so, which of the valves and/or stop pallets connected to the respective receiver unit are to be opened or closed.

Abstract: A wind instrument comprising a plurality of pipes each having a respective open. The instrument also comprises a plurality of movable elements each configured to move in relation to a corresponding one of the plurality of pipes and defining a respective movable end of the corresponding one of the plurality of pipes. Each of the plurality of pipes has an effective length defined by its respective open end and its respective movable end. The wind instrument further comprises a mechanism coupled to the plurality of movable elements, the mechanism being operative for simultaneously reciprocating each of the movable elements between a respective first position and a respective second position. The reciprocation of each of the movable elements induces an absolute change in the effective length of each of the plurality of pipes, the absolute change in the effective length being different for each of the plurality of pipes.

Abstract: There is provided a musical instrument comprising a plurality of elongated tubular members operative to generate specific sounds when blown therethrough. Each instrument body also has two opposing sides having a first radially extending female connector and a second musical instrument male connector, whereby the plurality of tubular members may be maintained in a generally parallel axis assembly.

Abstract: A pipe organ in which the operative condition of keys and stops is examined by time-division multiplex techniques to provide digital signals which can be transmitted to a pipe sounding section of the organ and/or recorded for subsequent transmission to the pipe sounding section of the organ, note/stop correlation between keys played and pipes to be sounded being effected by modification of the transmitted digital signals.

Abstract: This invention relates to pipe organs using tracker action and more particularly, to an improved such pipe organ having a separate wind-chest and sound-board fixed so that the air efflux from the valves of the wind-chest flows through flexible pipes and is delivered to the pipes supported on the sound-board.
