Abstract

When the on-on time between Note 1 and Note 2 is shorter than the double stop judgment time JT, as shown in FIG. 3A, the mode is changed from Unison 1 to Unison 2. When note-on information of Note 1 is inputted at time t1, the parts 1-4 are assigned to Note 1, and simultaneously start sound generation at pitch n1, as shown in FIG. 3B. Next, when note-on information of Note 2 at pitch n2 lower than Note 1 is inputted at time t2, the mode is switched to Unison 2. Part 1 (with the timbre being trumpet) and Part 2 (with the timbre being clarinet) which are higher in the pitch order are assigned to Note 1, and continue generating the musical sound at pitch n1 of Note 1, and Part 3 (with the timbre being alto saxophone) and Part 4 (with the timbre being trombone) which are lower in the pitch order are assigned to Note 2, stop the sound generation at pitch n1, and start sound generation at pitch n2 of Note 2.

Dependent claims

An electronic musical instrument, comprising:

an input device that inputs a sound generation instruction that instructs to start generating a musical sound at a predetermined pitch and a stop instruction that instructs to stop the musical sound being generated by the sound generation instruction;
a processor;
a computer readable storage medium having a control program executed by the processor to perform operations, the operations comprising:
generating a first musical sound at a first pitch in response to processing a first sound generation instruction from the input device, where the first musical sound comprises a plurality of parts comprising different timbres of different musical instruments;
receiving a second sound generation instruction from the input device to generate a second musical sound at a second pitch while generating the first musical sound;
determining whether a processing mode comprises a first or second processing mode;
switching the processing mode from the first processing mode to the second processing mode based on a first time at which the first sound generation instruction was received and a second time at which the second sound generation instruction was received;
in response to determining that the processing mode comprises the first processing mode, stopping the generating of the first musical sound and generating the second musical sound using the plurality of parts;
in response to determining that the processing mode comprises the second processing mode, assigning a plurality of parts to the first and second pitches by dividing the parts among the first and the second pitches and generating the first and the second pitches with the parts assigned to each to generate the first and second musical sounds.

6 more elements

A method implemented in an electronic musical instrument for generating electronic musical sounds, comprising:

receiving a first input of a first sound generation instruction to generate a first musical sound at a first predetermined pitch;
generating a plurality of parts comprising different timbres of different musical instruments at the first predetermined pitch to produce the first musical sound;
receiving a second input of a second sound generation instruction to generate a second musical sound at a second predetermined pitch prior to receiving a stop instruction for the first musical sound;
determining whether a time between receiving the first input and the second input is within a predetermined time;
in response to determining that the time exceeds the predetermined time, stopping the generation of the parts for the first musical sound and generating the plurality of parts at the second predetermined pitch to produce the second musical sound, wherein the parts at the second predetermined pitch comprise the timbres for the different musical instruments;
and
in response to determining that the time does not exceed the predetermined time, concurrently generating at least one of the parts at the first predetermined pitch to produce the first musical sound and at least one of the parts at the second predetermined pitch to produce the second musical sound, wherein at least one part generated for the first predetermined pitch is not generated for the second predetermined pitch.

4 more elements

An electronic musical instrument to generate musical sounds at different pitches, comprising:

an input device for receiving sound generation instructions to start and stop generating musical sounds;
a processor;
a computer readable storage medium including a control program executed by the processor to perform operations, the operations comprising:
receiving a first input from the input device of a first sound generation instruction to generate a first musical sound at a first predetermined pitch;
generating a plurality of parts comprising different timbres of different musical instruments at the first predetermined pitch to produce the first musical sound;
receiving a second input from the input device of a second sound generation instruction to generate a second musical sound at a second predetermined pitch prior to receiving a stop instruction for the first musical sound;
determining whether a time between receiving the first input and the second input is within a predetermined time;
in response to determining that the time exceeds the predetermined time, stopping the generation of the parts for the first musical sound and generating the plurality of parts at the second predetermined pitch to produce the second musical sound, wherein the parts at the second predetermined pitch comprise the timbres for the different musical instruments;
and
in response to determining that the time does not exceed the predetermined time, concurrently generating at least one of the parts at the first predetermined pitch to produce the first musical sound and at least one of the parts at the second predetermined pitch to produce the second musical sound, wherein at least one part generated for the first predetermined pitch is not generated for the second predetermined pitch.

7 more elements

A computer readable storage medium having code executed by a processor in an electronic musical instrument for generating electronic musical sounds by performing operations, the operations comprising:

receiving a first input of a first sound generation instruction to generate a first musical sound at a first predetermined pitch;
generating a plurality of parts comprising different timbres of different musical instruments at the first predetermined pitch to produce the first musical sound;
receiving a second input of a second sound generation instruction to generate a second musical sound at a second predetermined pitch prior to receiving a stop instruction for the first musical sound;
determining whether a time between receiving the first input and the second input is within a predetermined time;
in response to determining that the time exceeds the predetermined time, stopping the generation of the parts for the first musical sound and generating the plurality of parts at the second predetermined pitch to produce the second musical sound, wherein the parts at the second predetermined pitch comprise the timbres for the different musical instruments;
and
in response to determining that the time does not exceed the predetermined time, concurrently generating at least one of the parts at the first predetermined pitch to produce the first musical sound and at least one of the parts at the second predetermined pitch to produce the second musical sound, wherein at least one part generated for the first predetermined pitch is not generated for the second predetermined pitch.
