ABSTRACT:
The present invention relates to economically fabricated means for the generation and processing, member selection, and acoustic radiation of pluralities of individual tone currents originating from at least one high frequency source and formed by note-information temporarily transferred through key depression, from permanent electronic memories to temporary memories in small numbers of standard tone units, in precise duplication of properties of pipe organ sound.
There is described an electronic transfer organ for duplicating twenty-six known properties of pipe organ sound. The illustrative, inventive instrument employs completely standardized circuitry except for automatically programmable memories for each organ voice, which contain all the information required to form, switch and variously decouple all the notes in that voice. When keyboard keys are depressed, the information for corresponding notes is transferred to temporary memories in small numbers of tone units which then generate and switch the individual notes, without recourse to separate and permanent individual circuitry for each note. Dynamic keyers duplicate the keying effects of tracker action pipe organs. Sigmoid switches impart individualized tonal attack and decay patterns which preserve smooth keying at all speeds. All tone frequencies, derived ultimately from at least one high frequency source, are randomly independent in phase, and remain permanently in the various degrees of optimal mistune which characterize organ pipes in good tune. A four-channel sound system implements the effects of the tone frequency decouplings, and of a plurality of multiresonant filter sets, which together duplicate the collective sound of organ pipes distributed in various arrays within pipe enclosures. Construction is modular by keyboard and associated elements. Keyboard modules are subject to intercoupling by electronic or other means, and to augmentation by various devices in the prior art which effect expressive playing and moderate and musical fluctuations of tones, which are characteristic of organ pipe sound.
