Music Orchestrator is a native Mac workspace for musicians who want to turn ideas into organized score documents, from first sketch to orchestration, arrangement, rehearsal copy, and handoff.

Compose with structure

Build scores with instruments, voices, notes, lyrics, chord symbols, rehearsal marks, articulations, and metadata living in the document, not scattered across a layout.

Arrange for the ensemble

Move from sketch to instrumentation with a Mac-native scoring desk made for orchestration, arranging, teaching, copying, and production planning.

Keep projects portable

Save native .orchestra documents, bring in supported MusicXML or MIDI material, and export score data or PDFs when the music needs to move.

Creative workflow

From first sketch to shareable score.

Start from a blank score, setup wizard, MusicXML, MIDI, or an existing .orchestra project.
Develop the arrangement with notation, instrumentation, text, symbols, and layout controls organized around the music.
Save the score, print or share a PDF, and exchange supported material through MusicXML or Standard MIDI when a project needs to continue elsewhere.

Made for real projects

A cleaner scoring workflow for the work musicians actually do.

Use Music Orchestrator when a musical idea needs more than a scratchpad: a readable score, an ensemble plan, a document you can return to, and export paths for collaboration.

Compose original pieces, cues, exercises, theater numbers, chamber works, and ensemble arrangements in a focused notation workspace.
Use a native Mac document model when your score needs to be reopened, revised, copied, exported, and handed off.
Work with transparent import and export behavior that makes supported exchange practical without hiding file mismatches.
