Why do I hear noise or static at the beginning of a MIDI 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, or at the beginning of a QuickTime MIDI song. This is the result of a bug in QuickTime 6.x and can be fixed by changing the MIDI settings in QuickTime.
*Note that this fix changes the soundbank to one that might not be preferable in a MIDI authoring environment.
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.
