tone data is provided together with
tone data indicating a single key number, to thereby determine whether or not the chord is to be detected, and whether or not chord
tone data is be output. Accordingly, ways of sounding musical tones, such as changing a chord being played together with a solo being played, or not changing a chord being played but changing only the solo being played.ClaimsI claim:
1. A device for supplying sounding instructions in an electronic musical instrument comprising:
a plurality of sounding instruction means for generating on and off instructions for sounding a musical tone;
on determining means for determining on instructions of said plurality of sounding instruction means;
off determining means for determining an off instruction of said plurality of sounding instruction means;
first output means for detecting and outputting solo
tone data corresponding to the instructions generated by said plurality of sounding instruction means, according to a result of an on determination by said on determining means;
output terminating means for terminating the output of said solo
tone data by said first output means, according to a result of an off determination by said off determining means;
second output means for detecting and outputting chord
tone data corresponding to the instructions generated by said plurality of sounding instruction means, independent of said solo
tone data according to said result of the on determination by said on determining means;
switching means for switching said second output means, independent of said first output means between an operative and an inoperative state;
storing means for storing state data indicating the operative state or the inoperative state switched by said switching means; and
switching control means for controlling the switching of said second output means between the operative or inoperative state according to the state data stored in said storing means, independent of said first output means.
2. The device according to claim 1, wherein said first output means includes means for outputting
tone data indicating a single key number, and means for sounding a tone corresponding to said
tone data indicating a single key number.
3. The device according to claim 1, wherein said second output means includes means for detecting a c...
