    摘要： A digital electronic organ mixture system comprises a pair of digital organs operatively connected in parallel to the same keyboard or keyboards. The keys are grouped into regions of adjacent keys. In one of the parallel organ systems, the frequency numbers ascend along the keyboard corresponding to the notes associated with the keys. In the other parallel organ system, the frequency numbers are weighted by preselected factors, the factor being the same for each keyboard region, and the factor for each successive region along the keyboard being lower than the factor for the immediately preceding region. Activation of a key along the keyboard produces a pitch series comprising a note produced by the unweighted frequency numbers in one organ system and a second note produced by the weighted frequency numbers in the other organ system. The pitch series breaks back at each successive keyboard region in accordance with the weighting factor for that region. One or more additional complex wave forms may be stored in the organ system having weighted frequency numbers, to produce other tones in the pitch series.

    摘要： Spatially separated high frequency tonal effects from an electronic musical instrument having less tone generators than keys selectable. A high frequency speaker system is provided in addition to the normal audio system. The audio signals produced by the tone generator are applied to a high pass filter-amplifier circuit before application to a tweeter switch. Digital logic is provided to demultiplex the note generator capture signal for note generator assignment information. The demultiplexer information is applied to the tweeter switches to effect the activation of a tweeter switch and permit the sounding of the tweeter speaker. Thus it may be seen that the present invention permits the separate soundings of the high frequency range in a directional fashion, creating the movement of sound sources and changing spatial relationships in response to key activity.

    摘要： A touch sensitive system for an electronic musical instrument providing a multiple key switch contact system for effecting control over two or more tone generating systems. The first tone generating system operating rapidly in response to the actuation of the key switch to produce a desired voice. The second or subsequent tone generating systems operate sequentially in a delayed manner on the actuation of the key switch effecting a predetermined delay in the production of the desired voice. The audio output of each of the tone generating systems is summed forming a resultant waveform for audio amplification. The key switch actuation, depression and release, causes the tone generating systems to respond immediately to the depression or release of the key switch which effects a change in the envelope characteristics of the resultant waveform.
