You know I have to confess I have never tried either of
procedures as outlined by posts to the message board. It looks
like both methods work, under different circumstances. I suspect
the cable loop back method is the physical control surface/ midi
diagnostic. The latter method more of a "ctrlaltdel".
I probably will post those two methods on their own page
with the factory presets in sysex form. Both reset procedures
seem to have saved a few peoples butts. It would save people
having to hunt through the archive.
I wonder if it's possible to buy a service manual from
without being a "factory authorized" service center. I'd get one
if it were available.
