Abstract
Abstract An automatic rhythm performing apparatus capable of producing a rhythmic tone of a plural-tone-source rhythmic musical instrument such as a snare drum comprises a plurality of signal producing devices which produce a plurality of rhythmic tone signals corresponding to the respective tone sources of the single instrument. A control device controls respective signal levels of the rhythmic tone signals and a combining device combined the rhythmic tone signals at signal levels controlled by the control device to provide a combined signal corresponding to the rhythmic tone of the instrument, thereby providing a desired volume relationship of the respective component tones constituting the whole rhythmic tone of the instrument.

Claim 1
Independent Claim
132 words
An automatic rhythm performing apparatus capable of producing a rhythmic tone corresponding to a rhythmic musical instrument and constituted by a plurality of tone sources, comprising: (a) a plurality of means each for producing a rhythmic tone signal corresponding to a specific single tone source of a certain plural-tone-source rhythmic musical instrument; (b) control means for manually and non-independently varying signal levels of the respective rhythmic tone signals of said producing means in relation to one another to provide tone signals of desired relative levels; (c) means for combining respective outputs of said producing means at signal levels controlled by said control means thereby to provide a combined signal corresponding to a rhythmic tone of said certain rhythmic musical instrument; and (d) means for varying the signal level of said combined signal.
Claim 2
Dependent Claim
132 words
An automatic rhythm performing apparatus capable of producing a rhythmic tone corresponding to a rhythmic musical instrument and constituted by a plurality of tone sources, comprising: (a) a plurality of means each for producing a rhythmic tone signal corresponding to a specific single tone source of a certain plural-tone-source rhythmic musical instrument; (b) control means for manually and non-independently varying signal levels of the respective rhythmic tone signals of said producing means in relation to one another to provide tone signals of desired relative levels; (c) means for combining respective outputs of said producing means at signal levels controlled by said control means thereby to provide a combined signal corresponding to a rhythmic tone of said certain rhythmic musical instrument; and (d) means for varying the signal level of said combined signal.
Claim 3
Dependent Claim
83 words
An automatic rhythm performing apparatus capable of producing a rhythmic tone corresponding to a rhythmic musical instrument constituted by a plurality of tone sources, comprising: a plurality of tone source means for producing the respective single tone signals constituting said plural-tone-source instrument, control means for simultaneously manually varying the respective levels of said instrument-consisting tone signals in relation to one another to achieve a desired level relationship between the signals; and means for combining said level-controlled tone sources to produce said rhythmic tone.
Claim 4
Dependent Claim
83 words
An automatic rhythm performing apparatus capable of producing a rhythmic tone corresponding to a rhythmic musical instrument constituted by a plurality of tone sources, comprising: a plurality of tone source means for producing the respective single tone signals constituting said plural-tone-source instrument, control means for simultaneously manually varying the respective levels of said instrument-consisting tone signals in relation to one another to achieve a desired level relationship between the signals; and means for combining said level-controlled tone sources to produce said rhythmic tone.
