Electronic musical instrument, electronic musical instrument sound emission instructing method and non-transitory computer-readable recording medium

A sound emission instructing method for use in an electronic instrument, the method comprising:

• in a case where a music-playing operation on music-playing operators of the electronic instrument meets a first instruction condition that a plurality of the music-playing operators are not operated within a set time, instructing a sound source to emit a sound in a first sound emission form which corresponds to pitch data which meets the first instruction condition which is designated in accordance with the music-playing operation;
• in a case where the music-playing operation meets a second instruction condition that a plurality of the music-playing operators are operated within the set time, instructing the sound source to emit a sound in a second sound emission form which is different from the sound which is emitted in the first sound emission form and which corresponds to pitch data which meets the second instruction condition which is designated in accordance with the music-playing operation, in accordance with the plurality of the music-playing operators which are operated within the set time, and
• after the elapse of the set time, in a case where another music-playing operator is not operated in a time period from when a new operation on the music-playing operator to which sound emission is not yet instructed is detected and the new operation is started to when the set time elapses, instructs to emit a sound in the first sound emission form in response to the operation on the music-playing operator to which sound emission is not yet instructed.

A non-transitory computer-readable recording medium storing a program thereon, the program being executable by a computer in an electronic instrument to control the computer to perform processes comprising:

• in a case where a music-playing operation on music-playing operators of the electronic instrument meets a first instruction condition that a plurality of the music-playing operators are not operated within a set time, instructing a sound source to emit a sound in a first sound emission form which corresponds to pitch data which meets the first instruction condition which is designated in accordance with the music-playing operation;
• in a case where the music-playing operation meets a second instruction condition that a plurality of the music-playing operators are operated within the set time, instructing the sound source to emit a sound in a second sound emission form which is different from the sound which is emitted in the first sound emission form and which corresponds to pitch data which meets the second instruction condition which is designated in accordance with the music-playing operation, in accordance with the plurality of the music-playing operators which are operated within the set time, and
• after the elapse of the set time, in a case where another music-playing operator is not operated in a time period from when a new operation on the music-playing operator to which sound emission is not yet instructed is detected and the new operation is started to when the set time elapses, instructs to emit a sound in the first sound emission form in response to the operation on the music-playing operator to which sound emission is not yet instructed.

An electronic instrument comprising:

• music-playing operators each of which designates pitch data in accordance with a music-playing operation;
• and
• at least one processor which instructs a sound source which generates music sounds to emit sounds,
• wherein the at least one processor:
• in a case where the music-playing operation meets a first instruction condition, instructs the sound source to emit the sound with a first tone in a first sound emission form which corresponds to pitch data which meets the first instruction condition which is designated in accordance with the music-playing operation;
• and
• in a case where the music-playing operation meets a second instruction condition which is different from the first instruction condition, instructs the sound source to emit a sound with a second tone in a second sound-emission form which is different from the sound which is emitted in the first sound-emission form and which corresponds to pitch data which meets the second instruction condition which is designated in accordance with the music-playing operation, and
• wherein the sound source freely switches between (i) a first mode, in which sound emission is performed with the second tone which is generated by adding a sound effect to a sound which is emitted with the first tone, and (ii) a second mode, in which sound emission is performed with the second tone by using a sound source part block which is different from a sound source part block which corresponds to sound emission which is performed with the first tone.
