"I have 
your synthesizer Roland G-800......"
Well, if you were thinking that Roland rep's hang out here, you were wrong. This is just a site with a bunch of people who use synths, this happens to be the section to talk about Roland stuff. 
  Now, there are a few possibilities...... maybe those instruments' channels aren't set to transmit on the software sequencer, or maybe they are muted for some reason or another, or maybe the G-800 is running out of polyphony (although it would seem like the same problem would show with the disk drive) I really have no definite answer.
 If you want to contact Roland, there is an email address available at their UK site,
