Before you start

  • Windows 10 / 11 and an available trial or license.
  • A MIDI file and the instrument screen open in your game.
  • When you open DreamLyra, Windows shows a User Account Control prompt. Click Yes. DreamLyra runs as administrator so it can send keystrokes to the game.
  • The first time you open DreamLyra, the Quick start tutorial starts automatically and walks you through playing your first song with the Canon in your library. To follow this page on your own, first click Skip tutorial or press Esc. To watch it again later, click the ? button in the title bar, then click Replay the quick start.

Things to know

  • DreamLyra controls the game instrument through keyboard input; the game produces the sound.
  • If prompted to switch to the game, return to its instrument screen and press F8.
  • If the app reports that the game has higher privileges than DreamLyra (for example, because a system service started the game), restart the game normally.

First performance questions

No sound after installation?

DreamLyra turns MIDI into keystrokes; it does not output audio. Sound comes from the game. Open the game instrument screen, check the game volume, and verify the key profile.

F8 does nothing?

Check that DreamLyra is open, your trial or license is active, and a MIDI file is loaded. In MIDI file mode, F8 pauses or resumes playback. In creator mode, F8 starts or stops recording. Check whether another app uses F8.

The game does not respond to playback?

Set a 3- or 5-second start delay. Press play and return to the game instrument screen before the countdown ends. Keep the game in the foreground. If prompted to switch to the game, return to the instrument screen before pressing F8.
