Abstract: Systems and methods for creating, modifying, interacting with and playing music are provided, preferably employing a top-down process, where the user is provided with a musical composition that may be modified and interacted with and played and/or stored (for later play). The system preferably is provided in a handheld form factor, and a graphical display is provided to display status information, graphical representations of musical lanes or components which preferably vary in shape as musical parameters and the like are changed for particular instruments or musical components such as a microphone input or audio samples. An interactive auto-composition process preferably employs musical rules and a pseudo random number generator, which may also incorporate randomness introduced by timing of user input or the like.

Abstract: A method of performing audio synthesis has a first audio event input to an audio algorithm along with associated parameters. A synthesis algorithm accesses a soundbank to generate audio output. The soundbank has two or more levels for a first desired sound. A first level is associated with a first sample of a relatively chaotic waveform, and a second level is associated with a second sample of a relatively stable waveform. Parameter data is associated with one or more of the levels. The first sample and the second sample begin to sound at the same point in time in response to the first audio event. The audio output is based in part on the parameter data, and the second sample is continuously looped until a second audio event is detected.

Abstract: A method for remixing a music piece includes providing a music composition graphical user interface on a portable communications device. The music composition graphical user interface displays a plurality of actionable menu items. A first collection of actionable menu items is provided to the graphical user interface from an internal source. A music remixing algorithm incorporates music rules and can remix the music piece in a manner where only one musical component is remixed at a given time. A music remix database is accessible via the graphical user interface. A plurality of music remix data is organized based in part on a music style parameter. A second collection of actionable menu items is provided from the music remix database to the graphical user interface via a communications network. The first and second collection of actionable menu items displayed in a seamless manner.

Abstract: A method of performing audio synthesis is disclosed. An audio event is input to an audio algorithm along with associated parameters including source sample data. An interpolation function is provided and the source sample data are interpolated to generate one or more interpolated samples based on the source sample data. A filter function is provided and at least one of the interpolated samples is filtered to generate a filtered sample. A gain function is provided and the filtered sample is processed to generate a gained sample. At least one of the interpolation, filter, and gain functions include outputting an earlier-calculated value along with an estimated difference value in lieu of calculating a new value.

Abstract: Systems and methods for creating, modifying, interacting with and playing music are provided, particularly systems and methods employing a top-down process, where the user is provided with a musical composition that may be modified and interacted with and played and/or stored (for later play). The system preferably is provided in a handheld form factor, and a graphical display is provided to display status information, graphical representations of musical lanes or components which preferably vary in shape as musical parameters and the like are changed for particular instruments or musical components such as a microphone input or audio samples.
