Key transposing electronic organ |
摘要 |
A transposing electronic instrument wherein the clock frequency applied to control a top octave frequency generator is derived by comparing any single output of the generator with the response of a frequency reference circuit to that output, deriving a dc voltage representative of the difference in frequency of the input and output of the reference circuit and controlling the clock frequency from the dc voltage, thereby transposing all the outputs of the top octave frequency generator.
