I use the JAVA Script below since Netscape 4.x changed the way it 
plays MIDI.
Put the name of your MIDI file in the two places you see 
"yourmidi.mid".
The bgcolor= is the bacground color of the player. 
The txtcolor= is the counter color in the player.
Be very careful with this file Do not copy the text after you 
turn word wrap on. If it is on then turn it off.
Copy this file and paste it to your HTML document.

<SCRIPT LANGUAGE="JavaScript"> 
<!-- // Script for Crescendo MIDI playing.   

  if (navigator.appName == "Netscape") { 
     document.write('<EMBED TYPE="music/crescendo" ') 
     document.write('SONG="yourmidi.mid" ') 
     document.write('PLUGINSPAGE="http://www.liveupdate.com/dl.html" ') 
     document.write('HEIGHT=55 WIDTH=200 AUTOSTART="TRUE" LOOP="FALSE" bgcolor="#EFBD18" txtcolor="#000000"></EMBED>') } 
  else { if (navigator.appName == "Microsoft Internet Explorer") 
     document.write('<OBJECT ID=Crescendo ')
     document.write('CLASSID="clsid:0FC6BF2B-E16A-11CF-AB2E-0080AD08A326" ') 
     document.write('HEIGHT=55 WIDTH=200> ') 
     document.write('<PARAM NAME="Autostart" VALUE="TRUE"> ')
     document.write('<PARAM NAME="Loop" VALUE="false"> ') 
     document.write('<PARAM NAME="bgcolor" VALUE="#EFBD18"> ') 
     document.write('<PARAM NAME="txtcolor" VALUE="#000000"> ') 
     document.write('<PARAM NAME="Song" VALUE="yourmidi.mid"></OBJECT>')
     }
