A setting device includes an operating element and a light-emitting device. The operating element is used for specifying a setting value of a first parameter by moving the operating element within a first region. The light-emitting device includes a second region that is disposed inside the first region. The second region includes a light-emitting area that changes according to the setting value. The operating element covers part of the second region. The operating element is an operating element for specifying a setting value of a first parameter related to sound by moving the operating element relative to a housing. The operating element includes a first portion and a second portion. The first portion blocks light. The second portion transmits light from a first surface of the operating element to a second surface facing the first surface.

Methods and apparatus for providing metrics for the quality, attributes, and relationships of music including AI-generated music. Music classification and visualization methods are described that involve transforming music files into graphical representations, generating a similarity matrix for the music files using structural similarity techniques, and generating visualizations of the relationships among the music files using multidimensional scaling techniques. Qualitative scoring methods for AI-generated music are described that involve classifying the AI-generated music using a multi-genre classifier, generating a similarity metric for the AI-generated music to other genres using structural similarity techniques and multidimensional scaling techniques, and generating a qualitative score for the music using confidence in the classification in combination with the similarity metric.

An operation panel for an audio processing apparatus includes a plurality of components including a user interface that selects at least one output channel among a plurality of output channels and presents a first processing parameter, which indicates a send level from an input channel to the selected at least one output channel, and a second processing parameter different from the first processing parameter. The audio processing apparatus further includes a link receiver that receives, for at least two components, among the plurality of components, for setting a first link mode and a second link mode independently the first link mode for linking the presented first processing parameter, and the second link mode for linking the presented second processing parameter.

A keyboard device includes a plurality of keys, and a keyboard driver configured to drive at least a part of the plurality of keys. The keyboard device is configured such that sound is generated based on a first sound-generating process in which the keyboard driver is configured to drive a key corresponding to a first pitch, upon receiving performance data including the first pitch. The keyboard device is configured such that sound is generated based on a second sound-generating process that is different from the first sound-generating process, upon receiving performance data including a second pitch that is different from the first pitch.

Methods, Apparatus, and a System (collectively a “platform”) for facilitating, enabling, or enhancing creation, control, and playback of digital audio loops or parts are disclosed herein. The platform may include playing back midi song segments. The midi song segments may comprise a midi sequence that is looped a predetermined number of times. The platform may include transitioning to another midi song segment automatically after predetermined number of loops or transitioning in response to a command. The platform may include changing the number of loops during playback of a song segment in response to a command. The platform may relate to enabling automatic generation of song segments during a performance. The platform may include automatically selecting midi sequences to enhance playback. The platform may include other features pertaining to enhancing or enabling digital music creation or composition.

An audio processing apparatus includes: a plurality of channel operation controllers associated with a plurality of channels, each of the plurality of channel operation controllers configured to be operable by a user to control a parameter for one of the plurality of channels; a processor configured to determine a first channel, among the plurality of channels, to be assigned to a first channel operation controller, among the plurality of channel operation controllers; and a switching operation controller configured to be operable by the user to switch between a fixed mode where the first channel assigned to the first channel operation controller is fixedly set in advance and a custom mode where the first channel assigned to the first channel operation controller is arbitrarily settable. The custom mode includes a first state where the fixed mode is restored upon the switching operation controller receiving a first operation from the user, and a second state where the fixed mode is restored upon the switching operation controller receiving a second operation, different from the first operation, from the user.

A musical sound producing apparatus includes a plurality of keys; a sound production information generator configured to generate sound production information for producing a musical sound based on a first key operation on any key among the plurality of keys; a control information generator configured to generate control information for controlling, on the basis of a second key operation different from the first key operation, a mode of the musical sound produced on the basis of the first key operation; and a musical sound signal generator configured to generate a musical sound signal on the basis of the sound production information and the control information.

A sustaining device is described for prolonging the vibration of the strings of a stringed musical instrument, such as an electric guitar having two or three electromagnetic pickups. The pickups are all low impedance transducers that can function either as pickups or driver transducers, depending on whether they are connected to the input of the instrument pickup amplifier or to the output of the sustainer amplifier, respectively. When a transducer is being used as a sustainer driver, it cannot be simultaneously used as a pickup. Different methods of selecting transducers to function as pickups or drivers are described. The transducers, having only hundreds of wire turns instead of the usual thousands of turns for common pickups, have a flat audio frequency response that can be modified to produce a multitude of common pickup sounds by manipulating the transducer resonance frequency, bandwidth, and amplifier gain.

The present invention relates to systems and methods for visual image audio composition. In particular, the present invention provides systems and methods for audio composition from a diversity of visual images and user determined sound database sources.
