Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
A programmable rhythm device for use in an electronic musical instrument comprising: a pulse producing means for generating a sequence of pulses respectively corresponding to each individual beat of a rhythm pattern, a plurality of rhythm channels each receiving each pulse in said pulse sequence and each of said rhythm channels being individually programmable by an instrument player for producing an output control signal at selectable times corresponding to any desired beat of a rhythm pattern, and, said plurality of rhythm channels each comprising: a selection means for generating an enable signal, and, a plurality of logic circuit means each responsive to the simultaneous occurrence of said selection enable signal and one of said sequence pulses for programming said logic circuit.
Claim 2
Dependent Claim
121 words
A programmable rhythm device for use in an electronic musical instrument comprising: a pulse producing means for generating a sequence of pulses respectively corresponding to each individual beat of a rhythm pattern, a plurality of rhythm channels each receiving each pulse in said pulse sequence and each of said rhythm channels being individually programmable by an instrument player for producing an output control signal at selectable times corresponding to any desired beat of a rhythm pattern, and, said plurality of rhythm channels each comprising: a selection means for generating an enable signal, and, a plurality of logic circuit means each responsive to the simultaneous occurrence of said selection enable signal and one of said sequence pulses for programming said logic circuit.
Claim 3
Dependent Claim
25 words
A device as set forth in claim 1 wherein said programmed logic circuits pass subsequent sequence pulses corresponding to desired beats of a rhythm pattern.
Claim 4
Dependent Claim
79 words
A device as set forth in claim 1 wherein each of said logic circuit means comprises: a first AND gate responsive to said selection enable signal and said sequence pulse for producing a set output signal, a memory latching means responsive to said first AND gate for maintaining a latching enable signal output upon receipt of said set signal, and a second AND gate responsive to said latching enable signal and said sequence pulse for producing a pulse output.
Claim 5
Dependent Claim
30 words
A device as set forth in claim 3 wherein said logic circuit is programmed to pass said subsequent sequence pulses when said second AND gate receives said latching enable signal.
Claim 6
Dependent Claim
30 words
A device as set forth in claim 4 wherein said output pulse from each of said second AND gates combines to form said output control signal at the desired rhythm.
Claim 7
Dependent Claim
31 words
A device as set forth in claim 5 wherein said logic circuit means further comprises: an indicator means responsive to said latching enable signal for indicating said logic circuit is programmed.
Claim 8
Dependent Claim
38 words
A device as set forth in claim 1 wherein said selection means further comprises: at least one momentary selection switch means corresponding to each of said rhythm channels for enabling said instrument player to program said logic circuits.
Claim 9
Dependent Claim
66 words
A device as set forth in claim 1 further comprising: a voice generation circuit means responsive to said output control signal of each of said rhythm channels for producing a signal representative of an unpitched musical instrument at said programmed rhythm, and a transducer responsive to said voice generation circuit means for producing an audible sound output simulating said unpitched musical instruments at said programmed rhythm.
Claim 10
Dependent Claim
40 words
A device as set forth in claim 8 further comprising: a switching network responsive to said output control signal of each of said plurality of rhythm channels for connecting each of said output control signals to said voice generation circuit.
Claim 11
Dependent Claim
65 words
A device as set forth in claim 9 further comprising: a fixed rhythm matrix responsive to said pulse producing means for generating output pulse sequences in a predetermined standard pattern, and said standard output pulse sequence being applied to said switching network for permitting the instrument player to apply said programmed output control signals or said standard output pulse sequences to said voice generation circuit.
