MIDI: Noise At Beginning
Why do I occasionally hear noise or static at the beginning of a composition?
Occasionally you may hear static or a harsh noise on a PC when playing a MIDI program in QuickTime or in a browser using a QuickTime plugin. This is the result of a bug in QuickTime 6.x and can be fixed by changing the MIDI settings in QuickTime.
- Open QuickTime by going to Start > All Programs > QuickTime > QuickTime Player
- Go to Edit > Preferences > QuickTime Preferences.

- In the QuickTime Settings window go to the top drop-down menu and select Music.
- In Music settings choose General MIDI.
- Click the X in the upper right corner to close the settings window.
- Close the QuickTime player.
- Restart your browser.
