An AI innovation that composes, orchestrates, and performs full orchestral symphonies tailored to your mood, instruments, and musical ideas.

  • Developed by our expert team from the Dept. of Computing at PolyU, as part of the PolySmart intelligent-space ecosystem.
  • Integrates Generative AI for Music (MusicLang, Anticipatory Music Transformer, YuE), symbolic orchestration, neural audio synthesis (ViolinDiff, DDPM), source separation (Demucs), and professional stem mixing.
  • The prototype runs as an interactive web demo with a guided step-by-step UI; generated symphonies can be previewed, downloaded, and explored stem-by-stem.

What can PolySmart Prosinger Symphony do?

PolySmart Prosinger Symphony offers three creative modes on one platform: compose a short orchestral piece from scratch, transform a piano MIDI into a full symphony, or turn an AI-written song into a vocal-plus-orchestra performance.

1. Piano MIDI to Symphony

Turn a solo piano MIDI (preset classics or your own upload) into a multi-instrument orchestral symphony with expressive neural rendering and studio-quality mixing.

Select a preset piano MIDI or upload your own, choose orchestral instruments, and generate—a guided step-by-step workflow in the web demo.
The orchestrated symphony result: preview the mastered mix, listen to individual instrument stems, and download the final WAV.

2. Symphony Songwriter (Song → Symphony)

Describe a song style and theme, let AI craft lyrics, then generate a vocal song and re-imagine it as a symphonic arrangement with vocals preserved in the final mix.

Choose genre, mood, and tempo; enter a theme for AI-generated lyrics; then generate the full song-to-symphony pipeline with vocal and orchestral output.

3. Compose Short Music (Symphony Composer)

Pick orchestral instruments, a mood, and tempo—the system composes fresh multi-track MIDI and renders a complete symphony in about ten seconds.

Select instruments and mood, set tempo, and generate a short AI-composed orchestral symphony with downloadable stems.
