Notation · capability-scoped
Music notation that states what it knows.
One canonical score, exposed through only the available lenses.
Matra can expose Staff, Harmony, Hindustani Sargam or Carnatic Sargam without pretending they are interchangeable. 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. 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.
How it works
- 01
Describe, then upload
Upload audio you have the right to process and declare the tradition, material and recording role when known. Studio checks current limits as analysis starts.
- 02
Inspect the produced lenses
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
Correct the canonical score
Edit the available musical facts and retain the revision history. 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.
- Staff notation only when the Staff lens is available
- Harmony events with confidence when Harmony is available
- Separate Hindustani and Carnatic Sargam producers
- One canonical score for correction, playback and projection
- PDF, MusicXML and MIDI only when the result declares each export
Questions, answered.
Is this real notation or just chords over lyrics?
When the result declares a Staff lens, Matra renders score events such as notes, meter and key from the canonical graph. Harmony is a separate capability and is never implied by Staff availability.
How good is the notation today?
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.
Can I edit the notation?
Yes. Corrections create a new canonical score revision instead of overwriting the original result. 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.
Which editors and DAWs does it export to?
MusicXML, MIDI and PDF appear only for results that declare the corresponding export capability. Verify an exported score in your chosen editor before production use.
Can I get the chords of a famous song?
Matra accepts audio you have the right to process—your own playing, recordings or practice takes. It does not host a famous-song chart library, and the engine may abstain from unsupported or uncertain results.
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.
Built with the musicians who use it.
