“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.
A demo build is planned — leave your email via the support page and we will notify you when it ships.
A desktop computer from the last few years is plenty. Detailed per-OS requirements are published on the support page.
