Everything your ensemble needs
One platform instead of six different tools taped together. No separate modules to buy.

Split Any Recording Into Parts
Upload any recording and instantly get separate parts — vocals, drums, bass, guitar, piano, and more. Mute your part and play along with the rest.

URL Import & Conversion
Paste a link to any supported track and EnsembleOS pulls in the artwork, title, and audio automatically — ready to play or split into parts.

Confidence Tracking
Musicians tag their confidence on any passage. You see a real-time heatmap showing exactly where to focus rehearsal time.

Interactive Score Reader
Upload a PDF and it converts to a playable score automatically — individual parts are separated so musicians can solo their own line. Follow along with an auto-scrolling cursor, section highlighting, and measure-by-measure navigation.

Practice Mixer
Control the volume of each instrument separately. Mute the vocals to sing along, boost the bass to learn a tricky line, or create the perfect practice mix for any part.

Waveform Player
Loop any section of a recording or score, slow it down without changing the pitch, and practise at your own pace. Built for learning tricky passages.

Rehearsal Planning
Timed agendas, RSVP tracking, attendance recording, and pieces linked directly to rehearsal slots.

Analytics Dashboard
Who is practising, which pieces need work, engagement trends, and exportable reports for your committee.

Built-in Chat
Section rooms, @mentions, file sharing, and AI moderation. Built for ensembles, not borrowed from offices.

Section Rehearsals
Dedicated section practice with individual stem control. Mute your section, rehearse to the backing, then compare with the full mix.

Part Management
Upload separate scores and audio for each section or instrument. Members see their own parts first — sopranos get soprano, guitarists get guitar — with everything else a tap away.

Offline Mode
Download scores, stems, and audio to your device and practise anywhere — no signal required. Sessions sync automatically when you reconnect.

AI Assistant
Meet Manny — your built-in AI support assistant. Get instant help with any feature, step-by-step walkthroughs, and troubleshooting. Knows your ensemble, your role, and exactly where you are.


One recording. Every part separated.
Upload a recording and AI separates it into vocals, drums, bass, guitar, piano, and accompaniment. Instrumentalists mute their part and play along to the rest of the band. Singers solo the backing track and rehearse without the choir. Pianists isolate the accompaniment and practise tricky passages on repeat.
- Separates vocals, drums, bass, guitar, piano, and accompaniment
- Instrumentalists mute their part and play along
- Singers solo the backing track to rehearse independently
- Create instant backing tracks from any recording for your group to sing to
- Works with MP3, WAV, FLAC, OGG, and M4A
Know where to focus before you arrive
Musicians tag their confidence on any passage — confident, shaky, or lost. You see a real-time heatmap with problem areas ranked by severity and broken down by section.
- Three levels: confident, shaky, lost
- Per-section heatmap updated in real time
- Problem areas auto-ranked by severity
- One-click loop to drill any flagged passage




Upload a PDF. Get a playable score.
Upload a PDF score and EnsembleOS automatically converts it into a playable, interactive score — no manual conversion needed. Individual parts are separated so each musician can solo their own line. As the track plays, a cursor advances measure by measure in real time. Tap any measure to jump there instantly.
- PDF scores auto-converted to playable sheet music
- Parts separated — solo your line to learn it faster
- Real-time cursor synced to audio playback
- Tap any measure to jump — the player follows
- Director annotations shown inline on the score


Up and running in minutes
Three steps to transform how your ensemble prepares.
Create your ensemble
Set up your group, add sections, and invite members with a link or QR code. They join free — they never pay.
Add your music
Upload audio and PDF scores, assign each file to a section or instrument, and let AI separate stems and convert scores into playable sheet music — automatically. URL import and audio conversion tools are next in line.
Rehearse smarter
Musicians practise with the waveform player and tag their confidence. You see exactly who is prepared and where to focus.
What directors are saying
Ensembles of all sizes are transforming their rehearsals.
“EnsembleOS transformed our rehearsals. The confidence heatmap alone saves us 20 minutes every session — I know exactly where to drill before anyone walks through the door.”
Sarah Mitchell
Music Director
“We used to juggle WhatsApp, Google Drive, and a spreadsheet. Now everything is in one place. The stem splitting is genuinely magical for our band.”
James Carter
Worship Leader
“My students actually practise now because the tools are engaging. The waveform player with looping and tempo control is exactly what they need.”
Dr. Emma Lawson
Musical Director, University Ensemble

Frequently asked questions
Everything you need to know about EnsembleOS.
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.
