Provided is a signal processing apparatus having: a sound source separation unit configured to perform sound source separation on a mixed sound signal obtained by mixing a plurality of sound source signals; a sound source type determination unit configured to determine a type of a predetermined sound source signal obtained by the sound source separation; and an output destination control unit configured to output the predetermined sound source signal to a corresponding output device on the basis of a determination result of the sound source type determination unit.

A method and system for shaping the tone by modular circuit bending and modding of electric and electronic music instruments, audio amplifiers and sound equipment. The design of the system consists of a modding structure of a plurality of inserts, inputs and outputs connections for compatible modules, to reconfigure the electronic circuit without the physical changing of component values and without adding or removing electronic parts of the audio equipment by soldering. A plurality of tone modules for shaping the sound by the intervention into the signal path and a plurality of modules for shaping the tone by other sound design methods that are not part of the signal path are provided. For the modular system, an external device can be used as a multiplier, which consists of a plurality of inserts, inputs and outputs connections for compatible modules also including a plurality of combined series/parallel circuits of freely selectable inputs and outputs for the direct swap of a plurality of modding modules. In addition, switching options are available to control bypass, for advanced series or parallel connections, and for AB testing capabilities. The modular modding system can be used as a standalone device or as an upgrade to existing equipment.

A signal processing device includes: connecting terminals, each of which is connectable to respective ones of a plurality of other signal processing devices that are different from the subject signal processing device; an analog bus connected to the connecting terminals; an input terminal connected to the analog bus and that accepts an input of an audio signal; and an output terminal connected to the analog bus and that outputs an audio signal to a sound emitting device.

Methods and systems are described that are utilized for remotely controlling a musical instrument. A first digital record comprising musical instrument digital commands from a first electronic instrument for a first item of music is accessed. The first digital record is transmitted over a network using a network interface to a remote, second electronic instrument for playback to a first user. Optionally, video data is streamed to a display device of a user while the first digital record is played back by the second electronic instrument. A key change command is transmitted over the network using the network interface to the second electronic instrument to cause the second electronic instrument to playback the first digital record for the first item of music in accordance with the key change command. The key change command may be transmitted during the streaming of the video data.

A system and method for operating and performing a remotely networked virtual musical instrument. A client transmits musical control data to a remote server over the network, encompassing a digital music engine and digitally sampled virtual musical instruments. In return, the client consumes, synchronizes, and mixes the combined server playback stream from the network of the fully expressive and interactive musical performance with zero audible latency.

A system and methods for collaborating on a musical composition over a communication network, the system having processing circuitry that obtains the musical composition stored within a data storage device of the system, the musical composition including a first musical input data associated with a first channel, receives, via the communication network, second musical input data from a client device, the second musical input data being associated with a second channel, generates a data block based on the received second musical input data, the generated data block including synchronization data associated with the second musical input data relative to at least a portion of the musical composition, and transmits the data block to memory, the memory being accessible via the communication network to the client device and other client devices that are collaborating on the musical composition.

A method includes displaying a graphical user interface (GUI) for a step sequencer in a digital audio workstation. The GUI includes a sequence of user interface elements corresponding to a portion of a roll for an audio composition. Each user interface element in the sequence of user interface elements represents a respective time interval for a note. The sequence of user interface elements. The method includes receiving a user input interacting with a first user interface element. The method includes, in response to the user input: splitting a played note represented by the first user interface element into two or more played notes. The method further includes providing the audio composition for playback by a speaker.

Systems and methods are provided for assembling and displaying a visual ensemble of musical performances that were created and uploaded from one or more locations that are remote from a host of the network, a director or other administrator reviewing submissions for selection and assembly, or perhaps merely remote from one or more other submissions received over a computer network. The assembled performances include a plurality of submissions, the submissions including performances created and uploaded at one or more locations remote from the location of the director for the assembly and display over the computer network. Systems and methods are also included for mapping one performance against another performance qualitatively, quantitatively, in real-time, or some combination thereof, enabling a musician, or a reviewer of performances, in the assessment of one performance relative to another performance.
