Endorsed by the industry
“OrchestraX has completely transformed how I draft cues for director reviews. I can prototype complex, realistic modal frameworks in under ten minutes.”
“The voice-leading algorithms actually respect natural performance ceilings. It’s like having an orchestrator sitting right next to me on the stage.”
Everything you need to know about OrchestraX, from workflow to licensing and system requirements.
OrchestraX is a standalone algorithmic composition studio. You describe musical intent — themes, chords, roles like melody or bass, intensity over time — and engines built on music theory and constraint solving generate the orchestral parts. Nothing is a black box: every result is plain, editable MIDI.
No. OrchestraX works fully standalone with its internal preview sound. When you want your own sample libraries, seat an OrchestraX Chair plugin on each DAW track — it connects to the brain automatically, no virtual MIDI cables or routing setup.
The engine is style-agnostic orchestral writing: cinematic, classical forms, hybrid scores. You control harmony, rhythm rules, syncopation, density and expression — the style emerges from your choices, not from presets locked to genres.
No. One payment, a lifetime license. You can activate the software on up to 5 devices and free a seat anytime from your account — no email to support needed.
Yes. Everything you compose with OrchestraX is yours, for any project — film, games, advertising, releases. No royalties, no attribution required.
Export standard MIDI files, or skip files entirely: drag clips straight from OrchestraX into your DAW, or stream parts live through Chair plugins.
There is no demo version. Instead, your first purchase is covered by our 14-day money-back guarantee: if OrchestraX is not for you, request a full refund from your account within 14 days of purchase.
Within 14 days of purchase, sign in to your account and choose “Request a refund” next to your order. We review every request and refund you in full to your original payment method, usually within a few business days. The guarantee applies to your first purchase, once per customer; the license is deactivated when the refund is made. Everything you exported — MIDI files, scores, audio — stays yours.
OrchestraX runs on Windows, macOS and Linux, and one license covers all three:
