JavaSound Midi applet notes, Windows XP Applets using JavaSound MIDI ( javax.sound.midi ) will not work using the standard Sun Java plugin distribution. You must manually install a soundbank for the Java plugin to use or load one from the codebase of the applet. This doc describes how I loaded one into Windows JRE. To find out where your Java plugin is installed, open Control Panel. You will see either Java Plug-in or Java If Control Panel shows Java Plugin-in then do this: Control Panel -> Java Plug-in -> Advanced tab (read location under Java Runtime Environment listing) My Java plugin is in C:\Program Files\Java\j2re1.4.1_07 If Control Panel shows "Java" instead of "Java Plug-in", do this: Control Panel -> Java -> "Java" tab -> Java Applet Runtime Settings -> View, see "Location" In Windows Explorer, I browsed to C:\Program Files\Java\j2re1.4.1_07 and opened the "lib" folder In "lib" I made New Folder named "audio" You can download a soundbank of your choice at http://java.sun.com/products/java-media/sound/soundbanks.html From various jsdk installations, I found and copied soundbank.gm into the new audio folder [ C:\Program Files\Java\j2re1.4.1_07\lib\audio ] Note that you may have to rename the downloaded soundbank as "soundbank.gm" (for example, rename from soundbank-deluxe.gm to soundbank.gm) Loading an applet that uses JavaSound Midi plays midi notes ok now.
