For worship teams & songwriters
A capability-scoped lead sheet draft.
Staff and Harmony together—only when both are present.
A lead sheet requires more than an upload: the result must declare both Staff and Harmony. Edit the current score, transpose the view and review it before sharing or export.
How it works
- 01
Declare, then upload
Upload audio you have the right to process. Add musical context when you know it.
- 02
Open the declared result
Matra shows only the musical views the engine produced for that recording. If a view is unavailable, the Studio explains why instead of inventing a result.
- 03
Fix, then keep it
Editing always improves your chart. Your corrections (never your audio) also help improve Matra’s engines, separated from your account, unless you turn that off in Account › Privacy. Edit the current score, then export PDF, MusicXML or MIDI when that format is available for the result.
What you get
The result lists only the views and exports the engine produced.
- Harmony with per-chord confidence when the Harmony lens is available
- Declared key, tempo and meter when supported by the result
- Staff notation when the Staff lens is available
- Separate Hindustani and Carnatic Sargam lenses when produced
- Transpose the editable score when musical notes are available
- Capability-scoped PDF, MusicXML and MIDI export
Questions, answered.
Can I transpose for my vocalist?
You can transpose the editable musical score in semitone steps, then review the result against the recording.
Can I use it for worship sets?
You can process recordings and arrangements you have the right to use, then transpose and edit the private chart. PDF export is available only when the result declares it.
How accurate is it?
There is no single accuracy promise for every recording. Each available result carries its declared maturity and confidence, and you can inspect and correct the chart before using it.
What does it cost?
Invited members are not charged for analysis during the current private beta. Usage limits apply. Future credit, pack, subscription and discount policies have not been set.
Is my audio private?
Your recording stays private and can remain with your chart for playback or retry. Delete projects or your account yourself; see our Privacy Policy for retention and deletion. We never use your audio to train AI. Your corrections and your songs’ analysis (not audio) help improve Matra’s engines, separated from your account, unless you turn that off in Account › Privacy.
