A musical sound generation device including a first memory having a plurality of storage areas where waveform data is read out and stored, a waveform generator which functions as a plurality of waveform generating sections each of which generates a waveform for emitting a sound by reading out waveform data from a selected storage area of the first memory; and a control processor which determines, when an instruction for sound emission is provided, a combination of a waveform generating section and a storage area to be used for the instructed sound emission, based on a status of reading waveform data from each storage area by each waveform generating section.

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.

Provided is an electronic musical instrument. The electronic musical instrument is configured to generate an internal acoustic signal; generate a sound generation instruction signal; output the sound generation instruction signal to an external sound source configured to generate an external acoustic signal; switch a first state in which the external acoustic signal is generated by the external sound source in response to the sound generation instruction signal, to a second state in which the internal acoustic signal is generated in response to the sound generation instruction signal; and, when the first state is switched to the second state, set a mode of the internal acoustic signal such that the internal acoustic signal is generated with a mode having a predetermined degree of similarity to a mode of the external acoustic signal generated in the first state.

An apparatus for generating an audio output signal is provided. The audio output signal has two or more audio output channels and is generated from an audio input signal having two or more audio input channels. The apparatus includes a provider and a signal processor. The provider is adapted to provide first covariance properties of the audio input signal. The signal processor is adapted to generate the audio output signal by applying a mixing rule on at least two of the two or more audio input channels. The signal processor is configured to determine the mixing rule based on the first covariance properties of the audio input signal and based on second covariance properties of the audio output signal, the second covariance properties being different from the first covariance properties.

This tone setter comprises a memory for storing a program and a plurality of tone data; and at least one processor configured to utilize the plurality of tone data and set a sound source. In accordance with the program, the at least one processor executes accepting a selection of one or more tones made by an operation of a user; and setting, in at least an electronic musical instrument or a sound source of the tone setter, tone data corresponding to the selected one or more tones such that sound having the selected one or more tones is generatable with the musical instrument.

In one embodiment, an electronic musical instrument (EMI) (or electronic multi-instrument) is described that separates pitch choice from percussive sound control (articulation). A pitch sensor interface (by which notes are selected) may comprise a software-programmed touchscreen interface (that can be modeled on existing musical instruments or entirely new) configured to allow pitch choice, while sound control may be made on a separate articulation control sensor (by which notes are triggered and modified), such as an illustrative double-sided touch pad, that senses one or more of a velocity, pressure, movement, and location of a user's contact. The design facilitates a portable, ergonomic, and intuitive way to express music via standard digital protocols (e.g., MIDI) through a physical interface that encourages fluid, non-static, personally distinguishable musical expression. Notably, the instrument may illustratively be a controller that requires a compatible synthesizer sound source (e.g., on-board or separate).

A first input section is used for inputting first tone data, and a first output section is connected to the first input section via a first path. A second input section is used for inputting second tone data, and a second output section is connected to the second input section via a second path. A tone processing module performs tone processing on the tone data, and a processor is configured to insert the tone processing module into the first and second paths in response to selection of first and second modes, respectively. The tone processing module performs the tone processing on the first tone data in the first mode, and performs the tone processing on the second tone data in the second mode. The above allows connection of the module to be set easily in response to the selected mode.
