Electronic musical instrument with minus-one performance function responsive to keyboard play
First Claim
1. An electronic musical instrument having an automatic performance function, comprising:
- an input implement operable to input manual performance information;
detecting means for detecting operation and non-operation of the input implement;
musical tone generating means receptive of the manual performance information from the input implement for generating instant musical tones accordingly;
automatic performance means for feeding automatic performance information of a given musical composition composed of plural parts to the musical tone generating means so as to generate programmed musical tones accordingly;
allotting means for allotting a particular one of the plural parts of the given musical composition to the input implement; and
minus control means operative when the detecting means detects operation of the input implement for controlling the musical tone generating means to inhibit generation of programmed musical tones of the particular part while allowing generation of instant musical tones of the same part, and being operative when the detecting means detects non-operation of the input implement for controlling the musical tone generating means to restart generation of programmed musical tones of the particular part.

Abstract
An electronic musical instrument has a minus-one function to effect switching between full automatic performance and semi-automatic performance in which programmed musical tones are generated as automatic accompaniment except for melody and obbligato parts. A performance data memory records automatic performance data. A keyboard has a right key region allotted with the melody part and a left key region allotted with the obbligato part. A CPU controls the automatic performance according to operation of various switches including a song selecting switch, a start/stop switch and a minus-one switch for setting the minus-one mode. Under the minus-one mode of the automatic performance, instant musical tones are generated in response to the operation of the keyboard, while corresponding programmed musical tones are inhibited for the melody and obbligato parts when the key operation is detected on either of the right and left key regions.

7. An electronic musical instrument having an automatic performance function and a minus-one play function, comprising:
-
an input apparatus operable to input manual performance information; a detection circuit coupled to the input apparatus to detect operation and non-operation of the input apparatus; a musical tone generating circuit adapted to receive the manual performance information from the input apparatus and generate corresponding musical tones; an automatic performance circuit coupled to the musical tone generating circuit for providing automatic performance information of a given musical composition composed of a plurality of parts to the musical tone generating circuit to generate programmed musical tones corresponding to the automatic performance information; a designation circuit to designate a particular one of the plurality of parts of the given musical composition as corresponding to the input apparatus for minus-one play; and a minus-one control circuit that operates when the detection circuit detects operation of the input apparatus to control the musical tone generating circuit to inhibit generation of the programmed musical tones corresponding to the particular one of the plurality of parts designated as corresponding to the input apparatus for minus one play while allowing generation of the corresponding musical tones of the same particular one of the plurality of parts produced from the input apparatus, and that operates when the detection circuit detects non-operation of the input apparatus to control the musical tone generating circuit to restart generation of the programmed musical tones of the particular one of the plurality of parts designated as corresponding to the input apparatus for minus-one play. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of playing an electronic musical instrument having an automatic performance function and a minus-one play function, the method comprising the steps of:
-
periodically inputting manual performance instructions through an input apparatus; detecting the presence or absence of manual performance instructions from the input apparatus; generating musical tones corresponding to the manual performance instructions from the input apparatus; providing automatic performance information of a given musical composition composed of a plurality of parts to generate programmed musical tones corresponding to the automatic performance information; designating a particular one of the plurality of parts of the given musical composition as corresponding to the input apparatus for minus-one play; inhibiting generation of the programmed musical tones corresponding to the particular one of the plurality of parts designated as corresponding to the input apparatus for minus one play while allowing generation of the corresponding musical tones of the same particular one of the plurality of parts produced from the input apparatus when manual performance instructions are detected as being inputted through the input apparatus; and restarting generation of the programmed musical tones of the particular one of the plurality of parts designated as corresponding to the input apparatus for minus-one play when manual performance instructions inputted through the input apparatus have ceased. - View Dependent Claims (14, 15)
