Who it's for

For arrangers and composers

Offer rehearsal tracks with your arrangements. Basic adds part tracks and sharing; Premium adds mastering.

The problem

Getting a realistic read of a new arrangement means hiring singers or players, or rebuilding it by hand in a studio.

What you get

• Full mix plus Predominant, Split, Alone and Missing tracks for every part
• Hear voicing, transposition and key choices before you commit
• Works with any notation software that exports MusicXML or MIDI
• Offer permitted demo audio and rehearsal tracks alongside your arrangements
• Every note comes from your score — no generative AI rewriting it

How it works

1. Export MusicXML or MIDI from your notation software.
2. Check the detected parts, voicing and key.
3. Preview, adjust the sound, then share a listening page or downloads.

Plans: Features & plans. Your notes and recorded parts (Beta) — no generative AI.

For schools and educators

Practice tracks for every student's part, from the scores you already have.

The problem

Students learn faster when they hear their own part, but making tracks for every part of every piece takes hours.

What you get

• Full mix plus Predominant, Split, Alone and Missing tracks for each part
• Choirs, bands, orchestras, jazz and mixed ensembles
• Listening pages students open in a browser — no app or account
• Optional page passwords for class-only sharing
• Premium named playlists for classes and concerts; Basic listening pages include measure loops

How it works

1. Export MusicXML or MIDI from your notation software.
2. Check the detected parts and adjust the sound.
3. Share a listening page link or download the tracks.

Plans: Features & plans. Your notes and recorded parts (Beta) — no generative AI.

For choirs and ensembles

Learning tracks for every section, shared with one link.

The problem

Members arrive at rehearsal still learning notes, and paying for custom tracks for every arrangement adds up.

What you get

• Tracks for every part the day you get a new chart
• Choirs, worship teams, barbershop, bands and instrumental groups
• Stage positions that match where your performers stand
• Basic listening pages with pitch-preserving speed and measure loops; Premium adds click
• Premium named playlists for concerts, rehearsals and section practice
• Premium: use recordings of your own section leaders as parts (Beta)

How it works

1. Upload your arrangement, or one recording per part (Beta).
2. Set balance and Basic stage presets; Premium adds Mix & master.
3. Send members a listening page link.

Plans: Features & plans. Your notes and recorded parts (Beta) — no generative AI.

For musical theater companies

Your score, your tracks — rehearsal audio for every vocal line, ready in seconds.

The problem

Ready-made accompaniment can help with familiar shows, but original works and individual cast parts still need rehearsal tracks from your own score.

What you get

• Full mix plus Predominant, Split, Alone and Missing tracks for every part
• Any score you have the rights to: licensed shows, original works, custom arrangements
• Re-key or export a section where your licence permits
• Speed control that keeps pitch for learning tricky passages
• Premium named playlists for acts, rehearsals or the whole cast

How it works

1. Export MusicXML or MIDI from your score software.
2. Check the detected vocal parts and key.
3. Share a listening page with the cast or download the tracks.

Plans: Features & plans. Your notes and recorded parts (Beta) — no generative AI.

For learning-track makers

Premium Recorded parts (Beta): you record the parts. We build every mix.

The problem

Mixing Predominant, Split, Alone and Missing versions for every voice is repetitive work. Recorded parts (Beta) handles those mixes.

What you get

• Recorded parts (Beta): upload one audio file per part (WAV, MP3, M4A, OGG, FLAC or AIFF), or a ZIP
• Parts are named from your file names and ordered by pitch
• Every track type in one build, with consistent loudness
• Tone, gentle compression and finish presets on every track
• Listening pages for clients, with optional passwords

How it works

1. Recorded parts (Beta): export each part from your recording software, all starting at the same point.
2. Upload the files together using Recorded parts (Beta).
3. Choose tracks, then download them or share a listening page.

Recorded parts (Beta): you need the rights to your arrangement and recordings. Note fixes, instrument changes and speed don't apply; voicing and key changes pitch-shift the audio.

Plans: Features & plans. Your notes and recorded parts (Beta) — no generative AI.
