Abstract: An apparatus, method, and computer-readable storage medium that generate a harmonized musical piece. The method includes receiving a chord selection including a musical key and a scale selection, generating, within a digital audio work session, a chord progression sequence based on the received chord selection, in response to a detected chord selection change, modifying the chord progression sequence to include a chord progression corresponding to the chord selection change, setting the chord progression sequence as a master sequence, in response to detecting a second progression sequence within the digital audio work session, transmitting an identifier to the second progression sequence setting it as a slave sequence, and establishing a synchronized communication link between the master and the slave sequences such that changes made in the master sequence are automatically effectuated in the slave sequence, and combining the master sequence and the slave sequence to form a composed musical piece.

Abstract: An apparatus, method, and computer-readable storage medium that generate at least a cue point in a musical piece. The method includes generating a beat grid representing the musical piece, determining values for the beat grid, the values corresponding to an audio feature of the musical piece, and each value representing an entire duration of each beat in the beat grid of the musical piece, calculating a score for the audio feature at each of a plurality of positions in the beat grid of the musical piece, using some or all of the determined values, and generating the cue point at a particular position of the plurality of positions, based on the calculated scores.

Abstract: To purchase goods or services using an arbitrary cryptocurrency, an amount of the cryptocurrency can be transferred to a decentralized electronic ledger and an amount of another cryptocurrency can be transferred to another decentralized electronic ledger using cryptographic keys. A sequence of exchange operations is selected by which the cryptocurrency is exchanged for fiat currency, which include an entry into the decentralized electronic ledger requiring a cryptographic signature using the cryptographic keys and another entry into the other decentralized electronic ledger requiring another cryptographic signature using other cryptographic keys. A temporal window is determined defining a time in which the sequence of exchange operations is to be completed based on an estimated time for completion of the entry into the decentralized electronic ledger and an estimated time for completion of the other entry into the other decentralized electronic ledger.

Abstract: An apparatus, method, and computer-readable storage medium that compensate for latency in a musical collaboration. The method includes setting a tempo for a first client device to follow, receiving a musical piece from the first client device, transmitting the musical piece to a second client device, and instructing the second client device, via an instruction transmitted along with the musical piece, to delay playback of the musical piece a predetermined amount of time to compensate for latency in the musical collaboration, the predetermined amount of time being associated with a measure or a fraction of a measure.

Abstract: A method and apparatus for musical rhythmic composition. The method includes receiving a selection of a rhythmic template out of a plurality of available rhythmic templates, each of the plurality of rhythmic templates corresponding to a musical genre, and generating an irregular grid corresponding to the selected rhythmic template, the irregular grid including a plurality of blocks arranged side by side, at least one block of the plurality of blocks being irregularly spaced with respect to other blocks, each of the plurality of blocks representing a particular position at which a musical note is insertable to be in-rhythm with the corresponding musical genre of the selected rhythmic template.

Abstract: A musical composition processing system may include a storage device for storing reference musical compositions, an energy level characteristic value for each reference musical composition, and an attribute profile for each reference musical composition, and a computing device in communication with the storage device and for processing an input musical composition. The processing of the input musical composition may include determining an attribute profile for the input musical composition based upon transient and ambient sounds in the input musical composition, and determining an energy level characteristic data value for the input musical composition by correlating the attribute profile of the input musical composition to the respective attribute profiles and the energy level characteristic data values of the reference musical compositions.

Abstract: A system and method thereof for determining the musical key of a musical composition. The system includes a database of reference musical works, defined by both a root musical key and a note strength profile, and a musical key estimation system that detects the musical key of the musical compositing based on relationships between the note strength profiles of the reference works and the note strength profile of the musical composition.
