Abstract
Abstract An electronic musical instrument capable of achieving a variety of performance mode. A manipulation region to be played with a hand manipulator is divided into regions of different performance modes. Tone signal parameters are generated differently depending on the selection of the performance region. Tone generator generates musical tone signals based on the tone signal parameters. The tone signal parameters are determined based on coordinate information on the manipulation region designated by the hand manipulator and pressure information applied on the coordinate position by the hand manipulator. The tone signal parameters comprise velocity information, pressure information and tone pitch information.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
An electronic musical instrument comprising: performance receiving means for receiving performance manipulation, having a manipulation region of at least one dimension, said manipulation region having at least two zones, each zone containing a plurality of positions in which performance manipulation may be achieved; position detecting means for detecting a position of performance manipulation in said manipulation region and generating a position signal; selecting means for discriminating between a first zone of said manipulation region and a second such zone based on said position signal, and selecting a performance mode based on the zone so discriminated; controlling means for generating a tone controlling signal based on the performance mode selected by said selecting means; and tone signal generation means for generating a tone signal based on said tone controlling signal.
Claim 2
Dependent Claim
129 words
An electronic musical instrument comprising: performance receiving means for receiving performance manipulation, having a manipulation region of at least one dimension, said manipulation region having at least two zones, each zone containing a plurality of positions in which performance manipulation may be achieved; position detecting means for detecting a position of performance manipulation in said manipulation region and generating a position signal; selecting means for discriminating between a first zone of said manipulation region and a second such zone based on said position signal, and selecting a performance mode based on the zone so discriminated; controlling means for generating a tone controlling signal based on the performance mode selected by said selecting means; and tone signal generation means for generating a tone signal based on said tone controlling signal.
Claim 3
Dependent Claim
55 words
An electronic musical instrument as defined in claim 1, further comprising: pressure detecting means for detecting a pressure of said performance manipulation in said manipulation region and generating a pressure signal; and supplying means for supplying said pressure signal to said controlling means, wherein said tone controlling signal is further based on said pressure signal.
Claim 4
Dependent Claim
39 words
An electronic musical instrument as defined in claim 1, further comprising a manipulator for achieving said performance manipulation on said manipulation region, said manipulator transmitting a signal to said performance receiving means to indicate the position of performance manipulation.
Claim 5
Dependent Claim
29 words
An electronic musical instrument as defined in claim 2, further comprising a manipulator for achieving said performance manipulation on said manipulation region, said manipulator containing said pressure detecting means.
Claim 6
Dependent Claim
40 words
An electronic musical instrument as defined in claim 1, wherein manipulation in a first zone designates an ordinary performance and manipulation in a second zone designates a special performance, and wherein said first zone is larger than said second zone.
Claim 7
Dependent Claim
48 words
An electronic musical instrument as defined in claim 1, wherein said performance receiving means comprises a plane manipulation region and a pen shaped movable manipulator, and said position detecting means detects a coordinate on said plane manipulation region, said coordinate being designated by said pen shaped movable manipulator.
Claim 8
Dependent Claim
69 words
An electronic musical instrument as defined in claim 1, wherein said tone signal generation means includes closed-loop means for circulating a signal input thereto, said closed-loop means having at least one delay unit, excitation means for generating an excitation signal which is input to said closed-loop means and non-linear conversion means for converting at least the tone controlling signal according to a non-linear function to provide the excitation signal.
Claim 9
Dependent Claim
49 words
An electronic musical instrument as defined in claim 1, further comprising speed detection means for detecting a speed of said performance manipulation based on a time variation of said position signal and generating a speed signal, and wherein said tone controlling signal is further based on said speed signal.
Claim 10
Dependent Claim
57 words
An electronic musical instrument as defined in claim 8, wherein said controlling means generates a first tone controlling signal based on said speed signal when said selection means has selected a first performance mode and generates a second tone controlling signal based on a predetermined input signal when said selection means has selected a second performance mode.
