I've been trying to help a new PSR9000 owner get around his keyboard and since this is my first experience with this particular instrument I'm not too familar with the Operating System.
The problem we have is trying to edit Style sound volume levels, after a sequence has been recorded. For example, having made a recording, we wish to change the volume level of the Bass part or Drum part in the recording and then save the sequence back to Disk.
We spent quite some time looking through the User manual but have drawn a blank......
Can any PSR9000 user help ?

Thanks
