I would like to know what is the best way to
clean the disk drive of my keyboard. Can I use
the same cleaning diskette and solution as I
use with the computer? At the moment I have
Yamaha PSR-4000 and I am waiting for the new
PSR-9000. The problem is that we are run out
of PSR-9000 keyboards here in Finland. Can I
clean both keyboards the same way? I want to
keep all my keyboards on a top condition.
