Unlock Composers’ Full Potential with Specialized Tools

Traditional tools like Wwise, FMOD, or Metasounds are not specifically designed for music composition, often leading to a fragmented workflow. XJ provides a dedicated environment tailored to composers, streamlining the creation and implementation process. This not only enhances creative freedom but also ensures a seamless handoff to developers, reducing integration time and costs.

U.S. Patent 10,446,126

US Patent 10,446,126 describes a technology that creates unique, never-ending musical compositions. This technology could transform music production and consumption, particularly in the digital space.

What it is: This technology system generates unique, endless music compositions. It uses a library of partial musical documents and groups of audio samples provided by musicians. The technology uses this content to generate new, never-repeating musical compositions.

How it works: The technology starts by reading a library of musical content. It creates a new chain (a series of musical segments) from this content. It selects sequences (partial musical compositions) and matches them with appropriate instruments (groups of audio samples). Then it uses algorithms to determine the final arrangement and modulation (changes in pitch and tone) of the source audio to create a stream of unique audio data. This process can create an unlimited number of segments, each building and evolving from the preceding segments.

What it’s for: This system could be used in a Digital Audio Workstation (DAW) to enable artists to create endless musical compositions. Unlike a traditional static record which plays from beginning to end finitely, these compositions would perpetually change and evolve without ever repeating the same musical output. It opens up new possibilities for creating and experiencing music, with potential applications for live streaming, music-sharing platforms, and even music therapy.

In essence, this technology leverages partial musical compositions, instrument samples, and mathematical algorithms to create an ongoing, unique musical experience.
