| 摘要 |
<p>The invention relates to a programmable electronic metronome, capable of registering all meter and speed characteristics of any musical work and of producing, when the musical work is to be performed, substantially sharp, perceivable, e.g. acoustic, signals representing said characteristics in the appropriate succession. The metronome comprises a keyboard or other means for producing signals associated with at least three variables, which are bar number, speed and meter, and defining digital values for said variables, which values are stored in at least one volatile electronic memory, comprising segments severally correlated to each of said variables, to define digital data sequences. The metronome further comprises means for reading the data sequences, whereby to associate to each bar number digital values of speed and meter, and transducer means for trasforming said values into electric impulses, which produce a corresponding succession of perceivalble signals. Preferably further transducer means, having an inlet/outlet, are provided for transforming said data sequences into reconrding signals, which may be recorded onto and retrieved from a hard memory.</p> |
