A musical sound processing apparatus, a musical sound processing method, and a storage medium capable of generating musical sound full of interest are provided. The musical sound processing apparatus includes a first control unit configured to control a timing of sounding of a first tone in steps that come with an interval therebetween and a second control unit configured to control a timing of sounding of a second tone following or overlapping the first tone according to a first tempo, wherein the first control unit is configured to control the timing of sounding of the first tone according to the first tempo when timing information has not been acquired from outside and control the timing of sounding of the first tone according to a second tempo which is based on the timing information and different from the first tempo when the timing information has been acquired.

An electronic instrument includes a plurality of music-playing operators 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, in which 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 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 which is different from the sound which is emitted in the first sound-emission form, that is, in a second sound-emission form which corresponds to pitch data which meets the second instruction condition which is designated in accordance with the music-playing operation.

Disclosed herein are computer-implemented method, computer-readable storage medium, and DAW embodiments for implementing a music composition aid. An embodiment includes retrieving a first constraint value, receiving a selection of a set of musical elements, and accepting a second constraint value corresponding to the set of musical elements. Some embodiments further include invoking an iterator function, using at least the second constraint value as an argument, and generating an output of the iterator function, limiting a size of the output of the iterator function, according to the lesser of the first constraint value or a transform of the second constraint value. Output of the iterator function may include, of the set of musical elements, a subset determined by the second constraint value. The size of the output may be no more than the first constraint value. Further embodiments may render the output of the iterator function visually and/or audibly, for example.

A method for analyzing one or more notes in a musical composition, comprising for each note: getting a note, a chord and a scale. computing note properties using the note's value and the chord and the scale. A method for transforming one or more input notes into one or more new notes, comprising for each input note: getting an input note and its note properties, getting a new chord and a new scale for the input note, getting a list of notes candidates, computing distances between the input note and every note in the list, using input note's value, input note's note properties, candidate note's value and candidate note's note properties, finding the candidate that has the minimal distance, and setting a new note value using a note value of the candidate with the minimal distance.

Systems and methods for facilitating transactions of musical stems between users of an online gaming platform and mixing of the musical stems are disclosed. Exemplary implementations may: store information regarding tracks; transmit a purchase request regarding a given stem; receive a notification of the assignment of the right to use the given stem, wherein the assignment is recorded on a blockchain; obtain the given stem, generate an arrangement based on one or more stored tracks and the given stem, and playing back the generated arrangement.

Provided are systems and methods for transforming a digital score file into one or more of a plurality of levels of simplified visualization outputs. Methods of the present invention may be computer implemented. Systems of the present invention may include at least one display device, a non-transitory memory having instructions embedded thereon, and a processor in communication with the non-transitory memory and the at least one display device. Systems and methods of the present invention may be configured to receive at least one digital score file, upon which one or more simplification rules are executed, resulting in at least one simplified visualization output. Simplification rules may include, but are not limited to, song length, tempo adjustment, tie, rhythm, harmonic rhythm, and chord. One or more simplified visualization outputs are then provided.

In an electronic device for an electronic musical instrument, a determination grace period during which a plurality of operations on the electronic musical instrument by a user are determined to be simultaneously performed for the first section is set based on the data included in a first section of the song having a plurality of sections. Automatic accompaniment is advanced from the first section to the next second section when a user operation of the electronic musical instrument is detected outside of the determination grace period for the first section during the playback of the first section of the accompaniment, and automatic accompaniment is not advanced from the first section to the second section when the user operation of the electronic musical instrument is detected within the determination grace period for the first section during the playback of the first section of the accompaniment.

A method of motor vehicle detection and identification through audio propagation includes generating source autometric signatures; broadcasting autometric signatures; detecting the autometric signatures; visualizing the autometric signatures; determining known autometric signatures; and evaluating and sending autometric signatures to the motor vehicle.

The present disclosure describes techniques for controllable music generation. The techniques comprise extracting latent vectors from unlabelled data, the unlabelled data comprising a plurality of music note sequences, the plurality of music note sequences indicating a plurality of pieces of music; clustering the latent vectors into a plurality of classes corresponding to a plurality of music styles; generating a plurality of labelled latent vectors corresponding to the plurality of music styles, each of the plurality labelled latent vectors comprising information indicating features of a corresponding music style; and generating a first music note sequence indicating a first piece of music in a particular music style among the plurality of music styles based at least in part on a particular labelled latent vector among the plurality of labelled latent vectors, the particular labelled latent vector corresponding to the particular music style.

The disclosure provides an automatic performance apparatus, an automatic performance method, and a non-transitory computer readable medium. Notes to be sounded are stored in chronological order for each beat position which is a sound generation timing in a performance pattern. A probability of generating sound at the beat position is stored for each beat position in a sound generation probability pattern. According to the probability stored in the sound generation probability pattern, it is determined whether to generate sound or not for each beat position of the performance pattern.
