Shown at the AI Practitioner Summit · Oct 23, 2026

A film-scoring studio that asks before it assumes.

Drop in the picture. Six stages beside it put one thing on the timeline for every answer. THIRI voices the chords and fits a tempo to your moments, and says why. It runs on your Mac, and your sound libraries never leave it.

How it works

Six stages beside the picture.

Every answer puts one thing on the timeline. Skip a question and the studio says what it assumed, on the timeline, where you can change it.

  1. 01

    Bring it in

    Drop the film. Frame rate, length and cuts are read.

  2. 02

    Watch together

    What should I notice? Where does it turn? What should someone feel at the end?

  3. 03

    Mark the moments

    Click the moments that must land. Touch, hit or peak, and one hero. You hear them as clicks, louder the more they matter.

  4. 04

    Set the pulse

    Breathe freely, or lock to a beat: THIRI offers three tempos that land your moments. Bright, dark or unresolved suggests a key.

  5. 05

    Build the world, then the music

    Where are we? What sound does each moment make? Only then the instruments, and where they enter and leave. The guide proposes a plan; you approve it before anything runs.

  6. 06

    Listen and finish

    Too loud, too soft, missing? Export the mix, the stems, a cue sheet, credits and a verify report.

Measured, not promised

Every claim comes with a number.

Foley placed on the carving film
31 sounds, worst sync 1.0 ms
THIRI's tempo fit
120 bpm from four story hits, bar 1 at frame 6
Loops on the grid
every beat within 1 ms
The presentation's own score
8 of 8 cuts on their frame, bowl strikes within 0.02 ms
Delivered loudness
−16 LUFS, −1.5 dBTP, dead stops verified silent

The presentation above was scored by FYLLM itself; its verify report ships with the licence.

What ships

  • The studio: the six stages, the Moments lane, the spotting clicks, the THIRI frame.
  • The Csound instruments, measured.
  • Two palettes over your own folders: Loops (land on the bar) and One-shots (land on the frame).
  • Export: mix, stems, cue sheet, credits, verify report.

What never does

  • THIRI's engine. FYLLM talks to it over its API; the engine stays with Blues Prince Media.
  • Your Splice or Sonniss audio. Read in place, never copied, served or trained on.
  • Anyone's keys.

The six prompts that scored a film.

The exact words, in order, from the first film we scored with an agent: timing first, then the score, the real sounds, the hero moment, the notes and the mix. What each prompt made, and what we measured.

One email with the six prompts that scored a film, and the two-minute video. No list games.

Who

Built by Dennison Blackett, Blues Prince Media, with Dan Fazio, L2 Media, on his films.

Questions

What do I need?
A Mac, ffmpeg and Csound (the installer checks for both and tells you what is missing), your own sample folders, and a THIRI key for the voicings and the tempo fit. The first THIRI key is free at build.thiri.ai/keys.
Is it open source?
No. FYLLM is licensed software of Blues Prince Media. A licence covers one person. The repository is private.
Does it listen to my samples with a model?
No. Every sound carries words that code measured: dark, punchy, short, sub, noisy, wide. Nothing is uploaded and nothing trains on your library.
What does the voice need?
An Anthropic key for free conversation and plans. Without it, the six stages still run by their questions.
Who made it?
Dennison Blackett at Blues Prince Media, with Dan Fazio of L2 Media as the first filmmaker on it. THIRI is Blues Prince Media's harmony engine.
