Better musicians. Better rehearsals. Better music.

Yes. The Free plan includes 1 ensemble, 25 members, 5 repertoire pieces, the waveform player, score display, and basic rehearsal planning. No credit card required.

Never. Billing is handled by the director or organiser. Members get full access to every feature included in their director's subscription at no cost.

Upload a PDF score and EnsembleOS automatically converts it into a playable, interactive score with individual parts separated. Musicians can solo their own line to learn it faster. As the track plays, the cursor advances measure by measure in real time, highlighting the current position. Tap any measure to jump there instantly. You can also upload MusicXML files directly.

Upload a full audio mix and our AI separates it into individual stems — vocals, drums, bass, guitar, piano, and accompaniment. Use the built-in mixer to mute any part, solo yours, or create a custom practice mix.

Coming soon. The next audio workflow update adds supported URL imports with artwork and metadata preview, then stores the track inside EnsembleOS so you can prepare it for practise and stem work.

Most ensemble platforms focus on administration. EnsembleOS combines management with a professional practice suite — synced score reader, stem mixer, tempo control, confidence tracking, and section-specific rehearsal tools. No other platform does this.

Yes. Assign passages to individual sections. Each member can isolate their part using the stem mixer, follow along on the score reader, and tag their confidence. Directors see exactly which sections are prepared.

Yes. Fully responsive. Musicians can practise, view scores, use the stem mixer, tag confidence, and chat from any device.

No contracts. Monthly plans cancel anytime. Annual plans save 20% and you keep access until the end of your paid period.

Upload any PDF score and EnsembleOS automatically converts it into an interactive, playable format. Individual parts are separated so each musician can solo their own line. The converter handles standard notation layouts and produces a scrollable score with measure-by-measure navigation, auto-scrolling cursor, and section highlighting.

EnsembleOS supports MP3, WAV, FLAC, OGG, and M4A for audio uploads. For scores, you can upload PDF files which are auto-converted, or MusicXML files directly. Audio format conversion and optimisation tools are also on the way.

Yes. Depending on your plan, you can manage up to 5 ensembles from a single account. Each ensemble has its own repertoire, members, chat rooms, and analytics. The Organisation plan includes a cross-ensemble dashboard for managing everything in one view.

Musicians tag passages as confident, shaky, or lost while practising. Directors see a real-time heatmap showing exactly where each section struggles, ranked by severity. This means you walk into rehearsal knowing precisely which bars to drill — no more guessing or wasting time on passages everyone already knows.

Yes. Tap 'Download for offline' on any repertoire item to save scores, stems, and audio to your device. Practise anywhere without an internet connection. Practice sessions are queued locally and sync automatically when you reconnect — nothing is lost.

Yes. All data is encrypted in transit and at rest. Scores, recordings, and member data are stored securely and never shared with third parties. You can export or delete your data at any time.
