Abstract
Abstract A chord performing apparatus for an electronic organ with a chord-former, comprises control inputs for control signals defining the chord tone, and control inputs for control signals defining the chord type and control units which can be preset in accordance with a pattern of chord tones and chord types to be played and outputs which are scanned and controlled in the rhythm of the melody for performing the same function as the switch elements, connected with the control inputs of the chord-former.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
206 words
In combination a chord performing apparatus, an electronic organ provided with performance keys, a rhythm generating unit and a chord-former having at least one first control input means having first switch elements for providing first control signals for defining a chord tone and at least one second control input means having second switch elements for providing second control signals for defining a chord type, and a rhythm output signal derived from the organ in direct response to depression of performance keys of the organ during the playing of the melody of the music, said chord performing apparatus comprising first and second presettable control means for establishing a predetermined sequential pattern of chords of a selected tone and type corresponding to a sequence of the chords of the music to be played, said first and second presettable control means having scannable outputs adapted to be coupled to the organ, means for scanning said outputs in response to rhythm output signal derived from the organ during the playing of the melody of the music, said outputs being adapted to be coupled to the first and second control input means of the cord-former of the organ for generating chords of selected tone and type in said predetermined sequential pattern.
Claim 2
Dependent Claim
206 words
In combination a chord performing apparatus, an electronic organ provided with performance keys, a rhythm generating unit and a chord-former having at least one first control input means having first switch elements for providing first control signals for defining a chord tone and at least one second control input means having second switch elements for providing second control signals for defining a chord type, and a rhythm output signal derived from the organ in direct response to depression of performance keys of the organ during the playing of the melody of the music, said chord performing apparatus comprising first and second presettable control means for establishing a predetermined sequential pattern of chords of a selected tone and type corresponding to a sequence of the chords of the music to be played, said first and second presettable control means having scannable outputs adapted to be coupled to the organ, means for scanning said outputs in response to rhythm output signal derived from the organ during the playing of the melody of the music, said outputs being adapted to be coupled to the first and second control input means of the cord-former of the organ for generating chords of selected tone and type in said predetermined sequential pattern.
Claim 3
Dependent Claim
115 words
