I purchased an S80 about a week ago, and want to hook it up to my computer, which is an HP7360.  I think I want to use the TO HOST out and into the serial port.  Is that the best way for me to go?  I can't seem to find the correct adapter plug to go from the TO Host end...is this a proprietary thing?  I considered going from the MIDI out and in ports to the computer's joystick hookup, which I was told by a computer store that that would work.  Is that a valid way to go?  My computer has no Midi hookups to go into or out of.  I want to be able to download music to my keyboard, and also to arrange my own music with Cubase or Cakewalk, when I figure out how to use them  

  I'm pretty new to this synth stuff, so any help would be greatly appreciated!  I have found a lot of useful information on this BB so far.
Thanks much, Kar
