MIDI Out:
This example requires Jazz-Plugin v.1.0 or later.
If you have an external MIDI instrument connected to your computer, you will see its name in the drop-down list above. Select the instrument and press the button to play C chord on it.
Notice the try{...} block in the end of the script. It is required to get rid of error messages if the user has an old version of the plugin, or no plugin installed.
Alternative condition check if(Jazz.MidiOutList){...} does not work well with VBA controls in Microsoft Internet Explorer.
