Circuitry in an electronic organ for electronically storing a series of signals corresponding to depressed keys depression and for recalling the stored series in response to player commands. The circuit allows the player to play accompaniment chords of a piece of music alone and at any desired pace, and then while manually rendering the righthand, or solo, portion of the music. The chords are played by simply depressing a single control button whenever the next chord in the stored series is required. A further feature of the invention is the ability to store sets of switch or tab or other selector element settings for later recall. The selector element setting storage circuit enables the player to switch tab settings during storage of chords, while storing the patterns in the order in which they will be desired. A combination of the two features referred to allow a player to prestore both chord and tab information pertaining to a piece of music and recall both chord and tab information at will by pressing a single button. Information of any sort that can be selected can be stored by the arrangement according to the present invention including information pertaining to rhythms, presets, tremelo, vibrato, volume, or expression control as well as other selectable or variable elements under the control of the organ player.

Electronic organ with chord and tab switch setting programming and

A method and circuitry for frequency generation, especially for electronic organs, in which a digital signal is developed by the actuation of an element such as a key of an organ keyboard. The digital signal is converted to a respective voltage signal and the voltage signal is employed to control a voltage controlled oscillator which supplies a signal corresponding in frequency to the actuation of the aforesaid element. An organ provided with a system for frequency generation according to the present invention can be operated monophonically or polyphonically and is capable of producing desirable effects, including celeste and portamento effects.
