To try to answer your questions.
1. Unknown. It is one of those cards with music attached to it.
2. Unknown. All it says for the plugin is audio/midi. And when I go to the netscape plug-in page, and search under midi and Linux, nothing comes up.
3. Plugger is installed and running on my system.
Thanks for the help. I am still stumped as to what to do. I installed a midi player, or tried (it didn't install) and still nothing. Thanks again
