EnsembleOS
What it is
EnsembleOS is a web platform combining practice material, rehearsal planning, communication, and analytics for worship teams, choirs, and ensembles. Its waveform player loops recordings or scores and slows playback without changing pitch. AI stem splitting separates uploaded recordings into parts such as vocals, drums, bass, guitar, piano, and accompaniment. PDF scores can become playable scores with separated parts, a playback-synced cursor, and measure navigation; results depend on source notation and may need checking. Rehearsal planning includes timed agendas, RSVP tracking, attendance records, and pieces linked to rehearsal slots. Analytics show practice activity, pieces needing work, engagement trends, and exportable reports. Built-in chat offers section rooms, mentions, file sharing, and AI moderation. Audio uploads support MP3, WAV, FLAC, OGG, and M4A; scores support PDF and MusicXML. The service requires internet access for scores, audio, and most ensemble data, with no full offline media downloads. Directors or organisers pay while members use included features at no cost. The Free plan is £0 forever; paid plans start at £86.00 per year for Starter.

EnsembleOS covers rehearsal logistics, individual practice, communication, and reporting in one service. Its offline limits and score-conversion caveat are important for groups working away from reliable internet or with complex notation.
