Abstract
Abstract An electronic musical instrument has a generator assigner (2) for supplying note data and octave data by key stroke, a top octave synthesizer (3) for generating 12 highest pitch signals for each note, a circuit (5) for selecting one highest pitch signal from the 12 highest pitch signals according to note data, a binary counter (6) for dividing said highest pitch signal to produce several pitch signals, and circuits (7) for selecting one pitch signal out of several pitch signals obtained by the binary counter. Further circuits (10) are controlled by both octave data and note data to generate octave series tone signals and non octave series tone signals such as quint series tone signals.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
169 words
An electronic musical instrument comprising: a generator assigner which outputs assignment signals composed of note data representing the name of the particular note whose tone signal has been designated by a particular key stroke, and octave data representing the octave number of the selected tone; and a tone generator which has at least one pitch signal generating means and at least one octave controlling means, wherein said pitch signal generating means is controlled by the above mentioned note data and generates the highest frequency pitch signal corresponding to the note name of the tone selected, and further; said tone generator produces plural signals by dividing said highest frequency pitch signal, and wherein said octave controlling means is controlled by said octave data and selects pitch signals from said plural signals, and said pitch signals have octave number corresponding to the tone selected, and further, this octave controlling means contains means for modifying the octave number of the pitch signals to be outputted, having said note data as control input.
Claim 2
Dependent Claim
169 words
An electronic musical instrument comprising: a generator assigner which outputs assignment signals composed of note data representing the name of the particular note whose tone signal has been designated by a particular key stroke, and octave data representing the octave number of the selected tone; and a tone generator which has at least one pitch signal generating means and at least one octave controlling means, wherein said pitch signal generating means is controlled by the above mentioned note data and generates the highest frequency pitch signal corresponding to the note name of the tone selected, and further; said tone generator produces plural signals by dividing said highest frequency pitch signal, and wherein said octave controlling means is controlled by said octave data and selects pitch signals from said plural signals, and said pitch signals have octave number corresponding to the tone selected, and further, this octave controlling means contains means for modifying the octave number of the pitch signals to be outputted, having said note data as control input.
Claim 3
Dependent Claim
36 words
An electronic musical instrument as claimed in claim 1, wherein said octave controlling means contains means for choosing whether to modify the octave number of pitch signal outputted in accordance with said note data or not.
Claim 4
Dependent Claim
57 words
An electronic musical instrument as claimed in claim 1, wherein at least one of said tone generator contains at least two sets of said pitch signal generating means each of which supplies plural signals obtained by dividing the highest frequency pitch signal having a different note name, by the same assignment data sent from the generator assigner.
Claim 5
Dependent Claim
49 words
An electronic musical instrument as claimed in claim 1, wherein said tone generator contains output selecting means controlled by said octave data and receives pitch signals applied by said octave controlling means, so as to select the output terminal from which tone generator should output the according tone signals.
Claim 6
Dependent Claim
75 words
An electronic musical instrument as claimed in claim 1, wherein said octave controlling means consists of. a first means controlled by octave data that selects out octave-related plural pitch signals sent from said pitch signal generating means; and a second means having said note data as control input that selects out pitch signals from plural pitch signals obtained by said first means and outputs them thereof, whereby said pitch signals are outputted from tone generator.
Claim 7
Dependent Claim
76 words
An electronic musical instrument as claimed in claim 1, wherein said octave controlling means consists of: a first means controlled by note data that selects out octave related plural pitch signals sent from said pitch signal generating means; and a second means having said octave data as control input that selects out pitch signals from plural pitch signals obtained by said first means and outputs them whereby the pitch signals are outputted from said tone generator.
Claim 8
Dependent Claim
54 words
An electronic musical instrument as claimed in claim 1, wherein said octave controlling means consists of: converting means which converts octave data according to said note data; and means for selecting outputted pitch signals having octave number,to be outputted from said tone generator from plural pitch signals obtained by said pitch signal generating means.
