  • Patent number: 5550321
    Abstract: A foot operated electronic musical instrument with a plurality of foot actuated pedals, which correspond to the notes produced by a bass guitar. Depressing a particular pedal causes an electronic tone generator to produce a corresponding note. Pedals are generally provided only for natural notes, with the exception of A# and D#. In order to obtain the full chromatic scale, a flat switch is included. When engaged by the foot this switch has the effect of lowering the value of the note by one half step, hence adding a flat, or a sharp with respect to the next lower note.

  • Patent number: 5241130
    Abstract: An electronic musical instrument comprises a pitch designation device such as a keyboard, performance manipulators such as foot pedals, a tone color designation device such as tone color switches for designating a tone color, an effect designation device for selectively designating an effect as the effect assigned to at least one of the foot pedals on the basis of the selected tone color, and a tone generation control device for controlling the tone generation to be accompanied with the designated effect. That one pedal is assigned with a plurality of effects and a predetermined effect is automatically given correspondingly to the designation of the tone color of musical tone to be generated. For example, a sosenuto effect and a bright effect are selectively assigned correspondingly to the piano tone color and the non-piano tone color. Further, an intermediate output which increases continuously is generated when the pedal is pushed down.

  • Patent number: 4491050
    Abstract: A foot-controlled musical instrument, the control portion of which includes a heel rest mounted for rotation so that, while the heel of the playing person is firmly placed on the rest, the foot may easily be turned to various angular positions within a range of about 90 degrees, to bring the anterior part of the foot into position to make contact with any desired one of several (preferably six) pedal keys which, when activated, cause production of various sounds, e.g. according to a tonal scale. The pedal keys are mounted on a spring-loaded plate which may be depressed by foot pressure, the depression thereof serving to control certain characteristics of the produced sound. The heel rest plate is also mounted for movement in one or more linear directions in addition to its rotary movement, and these linear movements control other characteristics of the produced sound.

  • Patent number: 4488468
    Abstract: An electronic musical instrument including a compact, portable pedal board and a storage case for the pedal board and for the electronic components of the instrument is disclosed. The pedal board includes shortened foot pedals having a low profile and a very low throw for activating control switches for the electronics, whereby the pedal board can be used in conjunction with a piano or with other instruments. The low throw is obtained through the use of a guide channel mounting arrangement for the pedals and by the use of pressure sensitive switching.The storage case receives and secures the pedal board and also provides a housing for the tone generator, amplifier and other electronics controlled by the pedal board. A control panel door on the end of the storage case is adapted to receive a control panel, and is hinged to the storage case so that it may be swung fully open to expose the control panel.

  • Patent number: 4292874
    Abstract: Electronic and logic circuitry for an automatic tonal bass rhythm accompaniment feature and an automatic chord feature in an electronic organ. Automatic bass rhythm accompaniment produces a pattern of notes based upon a tonic note selected by the instrumentalist such that the desired musical effect is produced when the pattern of notes is combined with the notes being played by the instrumentalist. The electronic organ has stored in a memory various rhythm patterns which can be selected by the instrumentalist by closing rhythm switches. Electronic circuitry then causes notes for the selected rhythm pattern or patterns to be played automatically in response to the actuation of a pedal switch or keyswitch. The automatic chord feature of the present invention provides selectively major triad and dominant seventh chords or minor triad and diminished seventh chords automatically in response to the selection of a root note by the instrumentalist.

  • Patent number: 3962945
    Abstract: A musical instrument including an electronic organ provided with sound generators of an upper manual, a lower manual, a bass and a rhythm section. The sound generators are connected electrically to control switches in a console, these control switches being actuated by spaced horizontal, arcuately disposed, rows of main, switch actuating, pedals selectively operable by a person's left foot. The main pedals are disposed also in vertical rows corresponding to a basic note of a chord while the horizontal rows correspond to the key of each basic chord. A diode logic, in cooperation with the sound generators and control switches, dictates a prescribed chord of the lower manual sound generator to be sounded when a main pedal is depressed.
