Play a score

First steps

  1. Connect a MIDI keyboard
  2. Start Expresseur.
  3. Open a MusicXML file.
  4. The score is displayed, with a rythm part, added on the bottom.
  5. Play this rythm on the MIDI keyboard.

Catalog of scores

You can download any musicXML score available on the Internet, including the Expresseur musicXLM repository.

To create your own score :

  • optionally scan the paper of PDF score with a music-OCR software ( e.g. sharpeye  )
  • use any music-editor software to key-in notes, or arrange the score  ( e.g. the freewareMuseScore )
  • export the score in the MusicXml format

Advanced usage

Edit the parameters-file to change the interpretation of the MusicXML score 

A text file is added by the Expresseur. It contains parameters to interpret the score.

By default, this file has the  same name than the MusicXML file, with "txt" extension. It is possible to "save as" this text with another name, to keep different interpretations of the same musicXML score.

When you update the musicXML file with minor changes ( pitch error, .. ) : open the text file. It will load automatically the new version of the musicXML score, and apply the parameters of interpretation you've already set.

 When you change the structure of the musicXML ( new parts, ... ) : open the musicXML file. It will reinterpret the structure of the score in the text file. Former parameters can be copy-paste, with attention to the new structure.

The parameters contains differents sections :

  • The MusicXML score to load
  • The tracks in the score ( to change the name, make it visible, played or not )
  • The marks to set names of milestones in the score
  • The string of marks to play ( to organize repetition, codas, ... )
  • The ornaments, dynamics, instruments, ...

Play the score

 In the menu shortcut, it is possible to select the keys ( MIDI or computer keyboard ) which are used to play ( or move within ) the score.

In the rhythm track, generated by the Expresseur software, some notes have a number above ( e.g. x3 ) : it means that you have to play many ( e.g. 3 )  times to achieve ornaments attached to this current note.

A click on a note moves to this note. The command CTRL-G allows to go directly to a position.

Use the mixer to balance the tracks and set the instruments

Inside the mixer, you can tune :

  • volume with the cursors
  • device to play the tracks ( a MIDI piano, an SF2 soundfont, ... )
  • the instruments selected in the device ( list can be set in specific files )
  • the tuning of the instruments ( pan, ... ) 

To reuse common turnings between different scores, change the name of the tracks in the parameters-file

Playback the performance

Play the accompaniment on the Expresseur, after starting the recording ( menu edit /record playback).

Start the playback ( menu edit / playbalck )

Play your solo over your own playback, reading the score and following the accompaniment on the Expresseur.


Tips : when accompaniment does not play under the solo, add "silent note" in the accompaniment to help the synchro.

Connect a piano, or use a specific device

Any MIDI keyboard can be used.

When a numeric-MIDI-piano is connected, it is possible to play the piano-sound of this piano ( selct the right device in the mixer ).

For intensive use ( or specific issue linked to handicap ), it is possible to adapt MIDI devices ( pads, .. ), or to build ad-hoc MIDI devices.
