A method of operating a UI for controlling a virtual musical instrument implemented can include receiving an input corresponding to a selection of a cell within a particular array of cells arranged in a sequential arrangement within a cell matrix, each array of the cell matrix assigned to MIDI notes associated with audio sample data stored in a computer-readable medium that, when triggered, causes the audio sample data to output corresponding audio, and each cell within its particular array of the cell matrix, in response to being selected for playback and upon being triggered to begin playback, causes the audio sample data corresponding to the cell's particular array to be played. The method further includes determining that the input's duration is above a threshold time and expanding a size of an array containing the selected cell and adjusting the adjustable parameter of the selected cell based on the input.

The present invention provides method and system for composing music with chord accompaniment. One or more keys on a first keyboard are selected by end-users to generate a chord progression, and a computer generates a chord progression MIDI file, and associates the file with a first physical card that is embedded with a unique machine-readable ID (UID). After the UID of the first physical card is subsequently recognized, the chord progression MIDI file is retrieved and played. While the chord progression MIDI file is played, certain keys on a second keyboard are highlighted, and each of the highlighted keys on a second keyboard represents a music note that is in harmony with a particular chord in the chord progression while the particular chord is being played, and one or more of the highlighted keys on the second keyboard are selected by the end-user to compose a melody.

A system for playing a multi-string instrument utilizing a device in conjunction with hardware and software that once programmed on a computer using a touchscreen, solenoids press the strings down on the frets on the neck of a multi-string instrument, requiring a user to only need to touch the touchscreen and simultaneously strum the strings by any method.

A method, such as a computer implemented method, of data management, wherein content utilized by a first user can be identified and information about such content can be shared to at least one additional user such that the at least one additional user can pull the identified content from the content source.

In one embodiment, a method includes receiving, at a social-networking system an identifier corresponding to a post item stored in the social-networking system, and information indicative of a plurality of coordinated user gestures input into a composition interface control. The composition interface control comprises a plurality of interface targets each associated with a respective musical note. The information comprises target musical note and timing data associated with each of the user gestures. The method further includes translating the plurality of coordinated user gestures into a musical composition that includes musical notation reflecting the musical note and timing data of each user gesture. The method also includes associating the musical composition with the post item, and in response to receiving a request for the post item, formatting the post item and a graphical representation of each note in the musical composition for display in a user interface control.

A guitar pedalboard for creating a loop includes a touch screen display for displaying a plurality of tracks of a loop. The touch screen display can be used to adjust a parameter of each track, and the loop. A plurality of footswitches corresponding to the plurality of tracks can be used to independently record and play each track of the loop.

This disclosure relates to a method of displaying triggered by an audio, a computer apparatus, and a storage medium. The method comprises acquiring a background audio carrying a sound effect; playing the background audio, and generating a to-be-triggered area in a display page in response to playing to the sound effect; receiving an input trigger instruction, and detecting whether the trigger instruction matches the to-be-triggered area; displaying the to-be-triggered area according to a first preset effect in response to the trigger instruction matching the to-be-triggered area.

In some embodiments, an electronic device displays time-synced lyrics of content items playing on an electronic device. In some embodiments, an electronic device displays representations of content items in a playback sequence on an electronic device. In some embodiments, an electronic device shares an item of content with another user account of another electronic device.

A guitar multi-effects pedalboard is provided. The pedalboard has one or more footswitches, an electronic display, and a memory storing guitar-effect presets for processing an inputted guitar signal when the processing is triggered by pressing a footswitch. The presets include signal chains with two or more guitar-effect pedal simulators that simulate two or more guitar-effect pedals. The pedalboard also has one or more processors coupled to the electronic display and the memory. The processors are configured to process an inputted guitar signal when the processing is triggered by pressing a footswitch. The processors are also configured to display, on the electronic display, an image of the signal chains, which includes an image of pedals and an image of existing simulated connections between pedals. Signal routing in the signal chain may be changed by touching the image of a pedal and dragging the image to a destination position.

A method, such as a computer implemented method, of data management, wherein content utilized by a first user can be identified and information about such content can be shared to at least one additional user such that the at least one additional user can pull the identified content from the content source.
