Abstract
Abstract An electronic organ, piano or accordion has a transposing apparatus wherein a voltage-regulated high-frequency oscillator transmits high frequency signals to the input of a 12-tone divider circuit whose outputs transmit tone frequency signals to the tone generator of the musical instrument. The oscillator receives regulating signals from a switching unit, such as a multiplexer or a battery of integrated circuits, and the intensity of such signals is a function of addressing signals which are transmitted to the switching unit by an addressing unit having a keyboard with keys which are actuatable by the player to initiate the generation of different addressing signals as a result of closing of electric switches which are associated with the keys. The distribution of keys in the keyboard is the same as the distribution of playing keys in the keyboard of a piano, organ or a like musical instrument. If the keys are the playing keys of the musical instrument, the addressing unit is provided with an auxiliary switch which can be closed in response to actuation of a digital or a pedal to move from a first (open) position in which the keys are unable to effect the generation of addressing signals and act solely as playing keys to a second (closed) position in which the keys can effect the generation of addressing signals. The addressing unit is further provided with a storage whose output transmits to the switching unit a selected addressing signal until the player decides to actuate another key to thereby select a different addressing signal.
