Computing devices and methods for providing a music customization graphical user interface (GUI) to a user computing device are disclosed. The music customization GUI comprises song name selectors that each correspond to a different song and a music player region that includes a song customization selector. A customization window comprises music stem indicators that each correspond to at least one music stem of a selected song. The customization window also comprises mixing buttons that include a first mixing button configured to add a corresponding music stem to a user song mix, and a second mixing button configured to remove the music stem from the user song mix. A download button is configured to download a file comprising the user song mix to a user computing device.

A first device includes one or more processors and memory storing one or more programs configured to be executed by the one or more processors. The one or more programs include instructions for receiving, from a second device, audio mix information for a first audio item and receiving, from the second device, an indication that the first audio item is to be mixed with a second audio item distinct from the first audio item. In response to the indication, the one or more programs include instructions for transmitting to the second device an audio stream including the first audio item and the second audio item mixed in accordance with the audio mix information.

Indications of sample machine learning models which create synthetic content items are provided via programmatic interfaces. A representation of a synthetic content item produced by one of the sample models in response to input obtained from a client of a provider network is presented. In response to a request from the client, a machine learning model is trained to produce additional synthetic content items.

An electronic-drum module for connection to one or more electronic-drum pads is provided. The module includes an electronic display; a first memory storing audio files for playback when the playback is triggered by a signal received from a pad; and one or more processors coupled to the display and the memory. The processors are configured receive an instruction to transfer a set of samples. The set of samples is associated with a priority-instruction and includes a first subset of samples and a second subset of samples. The processors are also configures to transfer the first subset of samples from a second memory to the first memory based on the priority-instruction before transferring the second subset of samples and to transfer the second subset of samples from the second memory to the first memory.

A representation of a synthetic content item produced by one of the sample models in response to input obtained from a client of a provider network is presented. In response to a request from the client, a machine learning model is trained to produce additional synthetic content items.

A portable digital audio system for a musician. The digital audio system includes an amplifier for processing an audio signal from a musical instrument or microphone electronically connected to the digital audio system and a speaker for playing a sound associated with the audio signal processed by the amplifier. The portable digital audio system also includes an audio control system providing operational control of the digital audio system and a primary housing for supporting the amplifier, the audio control system, and the speaker. Further, the digital audio system has a touch screen display in electronic communication with the audio control system and supported by the primary housing.

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 reference part determiner determines a reference part from a plurality of parts including at least three parts. A subject part group determiner determines a subject part group from the plurality of parts, excluding the reference part determined by the reference part determiner out of the plurality of parts as a subject part group. An acquirer acquires a change pattern of a first audio parameter value set for the reference part. A changer changes a second audio parameter value set for the subject part group determined by the subject part group determiner according to a change pattern acquired by the acquirer.

A method includes displaying a user interface of a digital audio workstation, which includes a first region for generating a composition. The first region includes a first compositional segment that has been added to the composition by a user. Based on the first compositional segment, one or more recommended predefined compositional segments are identified and displayed in a second region. The method includes receiving the selection of a second compositional segment. The method includes adding the compositional segment to the composition.

An audio device being a mobile terminal includes: first and second playback units; and a display controller that causes a display to display a screen including an operation element for accepting a user operation. The display controller includes: a first display controller to display a first screen including an operation element for the first music data; a second display controller to display a second screen including an operation element for the second music data; a third display controller to display a third screen including a third operation element including one of an operation element for both the first and second music data or an operation element for adjusting an audio output ratio, the third screen not including an operation element related to the playback setting; and a display transition controller to display the first-third screens so as to make transition between the first-third screens based on the user operation.
