Abstract: An electronic device receives a source audio file from a user of a digital audio workstation and a target MIDI file, the target MIDI file comprising digital representations for a series of notes. The electronic device generates a series of sounds from the target MIDI file, each respective sound in the series of sounds corresponding to a respective note in the series of notes. The electronic device divides the source audio file into a plurality of segments. For each sound in the series of sounds, the electronic device matches a segment from the plurality of segments to the sound based on a weighted combination of features identified for the corresponding sound. The electronic device generates an audio file in which the series of sounds from the target MIDI file are replaced with the matched segment corresponding to each sound.

Abstract: Media content is electronically produced through the use of a graphical user interface, where a composition canvas area is presented. User input devices are used to select locations for one or more graphical elements, which represent media content such as tracks, instruments, or additional users, on the composition canvas area. The selection of a location identifies where the graphical element should be overlaid on the composition canvas. Based on the location of the graphical elements, at least a section of a digital composition is produced.

Abstract: This disclosure relates to editing an audio file of a time stream having a plurality of tones T. The stream is cut at a first time point of the stream, producing a first cut A cutting the stream into a first stream and a second stream, whereby each tone which extends across the first cut, is cut into a first part Ta which is in the first stream and a second part Tb which is in the second stream. For each of the tones extending across the first cut, a respective memory space is allocated to each of the first part and the second part, each of the memory spaces storing an original state of the tone. The first stream is allocated with a further stream, comprising adjusting the first part of one of the tones based on the information stored in the memory space allocated to said first part.

Abstract: 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.

Abstract: A system is provided for editing an audio file. The system displays, on an electronic device, a piano roll. The system receives a user input to cut a segment of the piano roll. The segment of the piano roll includes a respective tone that extends across both sides of the segment of the piano roll, such that the respective tone includes: a first portion of the respective tone that precedes the segment of the piano roll; and a second portion of the respective tone that follows the segment of the piano roll. In response to the user input to cut the segment of the piano roll, the system cuts the segment from the piano roll and, without user intervention, concatenate the first portion of the respective tone with the second portion of the respective tone.
