Made for music teachers
Lesson material that keeps your judgment.
Use the engine for a draft; use your ear for the teaching copy.
Upload material you have the right to process, then review the declared capabilities and correct the score. 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
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.
- Capability-scoped Staff, Harmony and Indian notation views
- Confidence and maturity cues for the review pass
- Canonical score correction with revision history
- Transpose per student when the chart supports it
- PDF, MusicXML and MIDI only when declared by the result
Questions, answered.
Can I make materials for copyrighted songs?
You can chart anything you record or play yourself, privately, for your studio. Matra doesn't publish or host transcriptions of copyrighted songs — your charts stay yours.
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.
