Abstract
An electronic organ provided with a selector for selecting a three-finger chord playing mode or a one-finger chord playing mode. When the three-finger chord playing mode is selected, a chord is sounded by three or four fingers on a manual keyboard or lower keyboard as in the conventional electronic organ. On the other hand, when the one-finger chord playing mode is selected, there can be automatically sounded one of chord types, such as major, minor, seventh and minor seventh chords, which have, as the root note, the note of a key being actuated on the manual keyboard. The selection of a chord type is effected by a pedal keyboard.
Claims23
An electronic organ comprising:
- a manual keyboard having keys;
- tone generators;
- keyer means coupled to said tone generators and responsive to key actuation on said keyboard so as to selectively derive at least one tone signal from said tone generators;
- automatic chord constituting means coupled to said tone generators and responsive to actuation of a key on said keyboard so as to selectively derive from said tone generators tone signals of notes constituting a chord whose root note is the note of the key being actuated, said automatic chord constituting means including:
- root note detector means for detecting the root note of a chord which is played on said keyboard;
- chord producing means coupled to said tone generators and to said root note detector means and responsive to said root note detector means for selectively deriving from said tone generators tone signals of notes constituting a plurality of chords having the root note;
- and
- chord type selecting means coupled to said chord producing means for selecting tone signals from said chord producing means for constituting one type of the chords;
- sound producing means;
- and
- selector switch means for selectively coupling one of said keyer means and said automatic chord constituting means to said sound producing means.
An electronic organ comprising:
- a manual keyboard having keys;
- a pedal keyboard having natural pedals and sharp pedals;
- tone generators;
- keyer means coupled to said tone generators and responsive to key actuation on said manual keyboard so as to selectively derive at least one tone signal from said tone generators;
- root note detector means for detecting the root note of a chord which is played on said manual keyboard;
- chord producing means coupled to said tone generators and said root note detector means for selectively deriving from said tone generators tone signals of notes constituting a plurality of chords having the root note of the chord being played on the manual keyboard;
- chord type selecting means coupled to said chord producing means for selecting one type of the chords from said chord producing means in response to a depression mode of said pedal keyboard;
- sound producing means;
- and
- selector switch means for coupling one of said keyer means and said chord type selecting means to said sound producing means.
