From a file to material you can use

Import MIDI or MusicXML

The overview reports duration, bars, notes, channels, polyphony, and resolution; use these values to understand the file before selecting anything.

Read tracks, timing, and the piano roll

The piano roll is both a reading tool and a selection surface: velocity, track selection, and timeline range determine what is played or exported.

Isolate one musical idea before exporting it

  • Drop a supported file and wait for its overview to load.
  • Use the piano roll and track controls to isolate the passage or voices you need.
  • Play the selection, then download or save MIDI or MusicXML when it is ready.
