Estimating the term…
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.
