Abstract

Abstract An electronic musical instrument with plural pitch data generating functions includes a keyboard, a plurality of tone generating units, a pitch designating unit, a plural pitch data generating unit, and a musical tone generating unit. The keyboard has a plurality of keys. The tone generating units generate at least two tone signals in response to operation of a key among the plural keys. The pitch designating unit designates a pitch of a musical tone to be produced. The plural pitch data generating unit generates at least two pitch data based on the pitch and in accordance with different scale characteristics. The musical tone generating unit generates at least two musical tone signals based on at least two pitch data respectively, so that at least two musical tone signals have the different scale characteristics.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 122 words
An electronic musical instrument comprising: a keyboard having a plurality of keys; a plurality of tone generating means for generating at least two tone signals in response to operation of a key among said plurality of keys; a pitch designating means for designating a pitch of a musical tone to be produced; a plural pitch data generating means for generating at least two pitch data with different scale characteristics based on said designated pitch; and a musical tone generating means for generating at least two musical tone signals having tone colors and pitches based on said at least two pitch data responsive to an operation of said key, so that said at least two musical tone signals have said different scale characteristics.
Claim 2
Dependent Claim 122 words
An electronic musical instrument comprising: a keyboard having a plurality of keys; a plurality of tone generating means for generating at least two tone signals in response to operation of a key among said plurality of keys; a pitch designating means for designating a pitch of a musical tone to be produced; a plural pitch data generating means for generating at least two pitch data with different scale characteristics based on said designated pitch; and a musical tone generating means for generating at least two musical tone signals having tone colors and pitches based on said at least two pitch data responsive to an operation of said key, so that said at least two musical tone signals have said different scale characteristics.
Claim 3
Dependent Claim 24 words
An electronic musical instrument according to claim 1, wherein said at least two musical tone signals have different tone colors and the same pitches.
Claim 4
Dependent Claim 165 words
An electronic musical instrument comprising: a keyboard having a plurality of keys; a musical tone generating means for generating a plurality of musical tones in response to operation of a key among said plurality of keys; a plurality of memories corresponding to said plurality of keys; an input device for storing pitch control data in said plurality of memories, said pitch control data representing a pitch to be generated corresponding to each of said plurality of keys; mode designating means for designating an input mode; writing means for writing, when the input mode is designated, the pitch control data according to operation of said input device in one of said plurality of memories corresponding to a depressed key; and pitch control means for controlling, when the input mode is not designated, a pitch of one of musical tones generated in response to the depressed key on the basis of the pitch control data in one of said plurality of memories corresponding to the depressed key.
Claim 5
Dependent Claim 165 words
An electronic musical instrument comprising: a keyboard having a plurality of keys; a musical tone generating means for generating a plurality of musical tones in response to operation of a key among said plurality of keys; a plurality of memories corresponding to said plurality of keys; an input device for storing pitch control data in said plurality of memories, said pitch control data representing a pitch to be generated corresponding to each of said plurality of keys; mode designating means for designating an input mode; writing means for writing, when the input mode is designated, the pitch control data according to operation of said input device in one of said plurality of memories corresponding to a depressed key; and pitch control means for controlling, when the input mode is not designated, a pitch of one of musical tones generated in response to the depressed key on the basis of the pitch control data in one of said plurality of memories corresponding to the depressed key.
Claim 6
Dependent Claim 24 words
An electronic musical instrument according to claim 3, wherein said input device comprises coarse adjustment input operating means and fine adjustment input operating means.
Claim 7
Dependent Claim 191 words
An electronic musical instrument with key tone generating function, comprising: a plurality of memory means corresponding to a plurality of keys of a keyboard, each of said memory means storing pitch control data concerning a corresponding one of said keys so that a scale corresponding to each of said memory means is formed, said formed scales being of different types from each other; input operating means for selectively performing one of a coarse adjustment operation and a fine adjustment operation; and rewriting means for rewriting pitch control data of one of said plurality of memory means which corresponds to a desired key in response to operation of said input operating means, said rewriting means rewriting the pitch control data in correspondence with the coarse adjustment operation for a relatively large pitch change amount and rewriting the pitch control data in correspondence with the fine adjustment for a relatively small pitch change amount, wherein a pitch of a musical tone generated in accordance with a depressed key of said keyboard is controlled on the basis of pitch control data of one of said plurality of memory means corresponding to the depressed key.
Claim 8
Dependent Claim 191 words
An electronic musical instrument with key tone generating function, comprising: a plurality of memory means corresponding to a plurality of keys of a keyboard, each of said memory means storing pitch control data concerning a corresponding one of said keys so that a scale corresponding to each of said memory means is formed, said formed scales being of different types from each other; input operating means for selectively performing one of a coarse adjustment operation and a fine adjustment operation; and rewriting means for rewriting pitch control data of one of said plurality of memory means which corresponds to a desired key in response to operation of said input operating means, said rewriting means rewriting the pitch control data in correspondence with the coarse adjustment operation for a relatively large pitch change amount and rewriting the pitch control data in correspondence with the fine adjustment for a relatively small pitch change amount, wherein a pitch of a musical tone generated in accordance with a depressed key of said keyboard is controlled on the basis of pitch control data of one of said plurality of memory means corresponding to the depressed key.
Claim 9
Dependent Claim 33 words
An electronic musical instrument according to claim 5, wherein said rewriting means rewrites the pitch control data of one of said plurality of memory means corresponding to a depressed key of said keyboard.
Claim 10
Dependent Claim 48 words
An electronic musical instrument according to claim 5, wherein said input operating means comprises one or a plurality of operating elements commonly used for the coarse and fine adjustment operations and selecting means for selecting whether said operating elements are used for the coarse or fine adjustment operation.
