Music Intelligence for Composition

Composer is Falcore's music intelligence and generation model for creating instruments, arrangements, accompaniment, and complete musical material.

Give it musical intent, context, or a starting point. Composer helps turn that direction into structured musical material you can shape, revise, and use in production.

What Composer does

Build the Musical Layer

Composer works across the parts of a composition that usually require different musical skills.

  • Instruments

    Generate complementary instrumental parts around an existing idea.

  • Arrangements

    Develop the structure, instrumentation, and movement of a piece.

  • Accompaniment

    Create supporting musical material around a melody, vocal, or existing track.

  • Variations

    Explore different musical directions without rebuilding the idea from scratch.

  • Complete musical material

    Move from a brief or musical starting point toward a fuller composition.

Context

Music Should Understand the Music Around It

Composer is designed to work with musical context rather than treating every generation as an isolated request.

It can be used around existing material, creative direction, timing, instrumentation, and the intended role of the music in a larger production.

Workflow

From Direction to Usable Material

  • 01

    Define the intent

    Start with a brief, musical idea, reference, or existing material.

  • 02

    Generate

    Create instruments, arrangements, accompaniment, or broader musical material.

  • 03

    Explore

    Compare variations and develop the direction that fits the work.

  • 04

    Shape

    Keep control over the creative result and continue refining it for production.

Built for creators

Expand What You Can Compose

Composer is designed for creators at different levels of musical expertise.

  • Singers

    A singer can build accompaniment without playing every instrument.

  • Producers

    A producer can explore arrangements faster.

  • Filmmakers

    A filmmaker can develop musical ideas around a scene.

  • Composers

    An experienced composer can use it as another instrument in the workflow.

Production

Built for Production Workflows

Composer is being developed for real creative work, where musical material needs to fit timing, context, structure, and the rest of the production.

The goal is not just to generate music. It is to make musical intelligence useful inside the process of creating it.

The Composer models

Two Generations. One Direction.

Composer evolves through successive model generations, each focused on improving the quality and usefulness of prompt-driven music generation.

Generation 1

Omni 1.0

Our first-generation Composer model, establishing the foundation for prompt-driven music generation.

  • First-generation Composer model
  • Prompt-driven music generation
  • Efficient inference
  • Foundation for subsequent Composer research
Latest generation

Omni 2.0

Our latest Composer model, developed with improvements across musical quality, prompt adherence and generation capability.

  • Latest Composer generation
  • Improved musical quality
  • Improved prompt adherence
  • Increased generation capability
Benchmark

Quality Is Measurable.

We evaluate Composer models across multiple dimensions rather than relying on a single measure of performance.

Internal evaluation. 18 requests: three song lengths (30, 120 and 180 s), two models, three repeats, interleaved. Timings were taken on a single laptop, not production infrastructure, and each cell has three runs, so individual figures are noisy. Quality figures are computed from the MIDI and audio files, not from listening tests. Both models completed every request.

Omni 2.0 is faster, cheaper and cleaner on most measures. Omni 1.0 stays slightly closer on loudness target and silence, and is more accurate on length for 30-second songs.

Applications

Built for Creative Workflows.

Composer can be integrated into applications and workflows that need programmable music generation. These are potential applications.

  • Film and video

  • Games

  • Advertising

  • Creative applications

  • Prototyping

  • Interactive media

  • Generative content systems

  • Research

API

Build with Composer.

Integrate prompt-to-music generation directly into your application or creative workflow through the Composer API. Whether you're prototyping a new creative tool or building a production system, the API gives you programmatic access to Composer models.

Public Access Is Coming Soon.

Composer is in development as we work toward broader public availability. API access is available by request for teams and individuals who want to build with it.
