AI music scoring · Powered by SiteSynth

Turn ideas into full scores, in minutes

An AI tool that transcribes, arranges, and scores music into professional orchestral sheet music — from nothing more than audio or MIDI.

ScoreSynth UI overview

// How It Works

From sound to score.
In just a few steps.

Hum a melody, export a MIDI, or upload a full demo — ScoreSynth turns any of them into a professionally arranged orchestral score.

No music theory required. No expensive software. Just your idea, and a score ready to perform.

Upload your source

ScoreSynth accepts MP3, WAV, MIDI, MusicXML, or even scanned sheet music. You can also describe what you want in plain words — or combine several songs and let it arrange from them.

AI analyses and separates the music +

Source separation (Demucs) isolates the musical layers, so the system understands what each instrument or voice is actually doing.

Transcription into digital notes +

The transcription engine (MT3) converts the input into structured notes, holding on to melody, harmony, and timing.

Orchestration with intelligence +

A custom orchestration model assigns parts to real instruments. Pick the ensemble and the difficulty — or just describe the group you are writing for.

Output: ready-to-use sheet music +

Clean PDF and MusicXML, ready to print or edit. Every version comes with AI playback, so you can hear the arrangement before anyone plays it.

Bridging two worlds — music and technology

// The Story Behind It

From musician.
To builder.

Before founding SiteSynth, I was a musician. I studied at the conservatory, spent years in orchestras, and worked with composers, arrangers, and ensembles of every shape and size.

Moving into technology never took the music away. I kept running into the same wall: turning a musical idea into actual sheet music meant expensive software, deep theory, or hours of manual work.

With ScoreSynth, that wall is gone.
