PARTITA STUDIO is a desktop studio where an AI agent plans the arrangement and writes MIDI parts with articulations and dynamics for your libraries. From idea to a score in your DAW — in minutes.

This is what a request to the agent looks like. Click a genre with ▸ to hear what it wrote for that prompt.

An Agent that steers your project to completion

Chat with it like a co-orchestrator: PARTITA STUDIO parses your project structure, consults the orchestration knowledge base, plans out sections, and generates parts step-by-step.

  • Reads the score and works with what is already written
  • Shows its plan and ticks off finished steps right in the chat
  • Generates parts one by one and reviews its own results
  • Every edit shows up as a chip — the project can roll back to any revision

PARTITA STUDIO — heroic piano motif
Write a heroic piano motif in D minor, 108 BPM
Reasoning
I need a short miniature in D minor, 108 BPM, 4/4: a heroic core, rising action towards the climax, and dense harmony in the middle.

How it Works

Three steps from idea to finished music

You express what you want to hear. PARTITA STUDIO turns it into an arrangement with parts for every instrument.

1. Describe your vision

Type in the chat: "heroic march for orchestra" or "tender theme for strings and flute".

2. PARTITA STUDIO plans

Instrument selection, piece structure, and entry points — without manual track laying.

3. Ready MIDI

Parts with dynamics and articulations. Export to a file or route MIDI to your DAW via a virtual port.

PARTITA STUDIO workspace: arrangement timeline with the agent chat, the bar-replace capsule and the MIDI editor with velocity and articulations
One project, three states in a row: the agent plans the arrangement, you select the bars, the editor shows every note. Timeline and agent chat Replacing the selected bars Piano roll: velocity and articulations
Timeline

From text to orchestra in one window

The entire process — from idea to multi-track arrangement — stays in the app: timeline, blocks, clips, curves, and a full-range MIDI editor.

Knowledge and sound

Use Cases

A new way to drive an arrangement to ready MIDI

Typical tasks — no made-up names, just roles and results.

I used to manually place winds and check ranges. Now I state my intent and polish the parts in the editor.

Needed an orchestra for a video in one evening. Got the skeletal arrangement and exported MIDI to Cubase.

I watch the AI build the score block by block — it’s a great way to study orchestration from actual parts.

Composition and Orchestration

Nucleus and CSS in out-of-the-box profiles. Keyswitches and CC sequences don't break articulations.
