摘要： A large scale integrated circuit chip (38) for an electronic organ system (Fig. 1) is provided which produce chords (40,44) and bass frequency (38) generation (12, 16) and identification (98), It automatically coordinates with another chip in rhythm production (88, 90). It incorporates frequency generators (12, 16), identifies a chord played (98), and provides keyers (20, 22, 24, 26) for chord notes.

摘要： A piano action is provided for an electronic piano. Tones are generated electronically, but the action retains the feel of a conventional piano action without the necessity of a hammer or hammer-like member. The piano key (28) is provided with a rounded, convex shoulder (58) which presses against a rounded, convex surface (86) on a lever (74). The two convex surfaces are configured and positioned so that one slides over the other to provide the feel of let-off of a conventional piano action. The lever is spring-biased by means of two different springs (94, 114) to rest position, and acts to move a spring wire contact (118) from a first bus (116) to a second bus (120).

摘要： in a modular, expandable organ system comprising a plurality of large scale integrated circuit (LSI) chips an LSI chip (286, Ftg. 4) is provided which produces frequencies corresponding to notes played on an organ keyboard. Outputs of different duty cycles (230, 138, 140, 142, 144) of rectangular waves are provided for best simulating desired sounds. Other outputs are provided in which the notes are in octave groups (244) facilitating filtering thereof. Each group of outputs has different attack and decay (162, 190, 228, 246, Fig. 2) characteristics respectively under the control of the organist so that similar or different type of attack and decay may be provided on different outputs.
The present LSI chip provides three generators (26, 36a, 36b, Fig. 4) on one chip. The chips are capable of being interconnected (290) such that any multiple of three generators may be provided.-

摘要： In an electronic organ or the like constructed of a plurality of large scale integrated circuit (LSI) chips, the present disclosure relates to a generator chip (Fig. 2). The chip is operative over one octave of notes, and a string of chips (Fig. 4-134, 136. 138, 140, 142, 144) is cascaded to provide as many octaves as there are in the instrument.
