Hi all,
(and a Happy New Year !)
(with the Great Sysex Mystery solved... ;-)  )

I just wonder why we, proud owners of a DKV, do not get an easy access
to the secrets of the DKV proprietary sysexes... I tried and could not
solve the puzzle of Yamaha's Smartkey sysex.
(I wanted a singer to be able to start her piano accompaniment by
merely playing a few notes (ending with the one that "shows up" by
silently moving), then leave the piano to its invisible player and
sing :  a very effective  trick when singing "Remember me" from
Orfeo...  No way.)
Does anybody have a solid connection to Yamaha in order to get those
infos?
I can understand that Yamaha does not want anybody get an access to
mantenance mode.  I saw my Yamaha tech enter this mode, then tried it
myself, and guys I don't want to get further into this without the
technical manual he used ! <G>
But as far as sysexes are concerned, this is a knowledge only midi
dedicated people could use, and it would not mean any harm to the
pianos (harmful codes could easily be kept secret...)
I've been trying to get those Smartkey infos for months, and could not
get an answer from Yamaha Europe. So I am among those, like Mark
Fontana or Midi Magic, who spend time to try and decipher unreleased
codes.
This is the same for the way Yamaha (brillantly but secretly) coded
the midi into .wav on the  right track of their  Pianosoft plus
CD's...  Why  don'they simply give the technical infos to the people
who need them to use their DKV in  an even more creative way ?
My play for children  "le piano de Nanette" (Granny's piano) makes
adults and children wonder before the amazing piece of art Yamaha
built. I could make it even more magical, but Yamaha seems more
interested in having their DKV play  easy listening music in hotel
lobbies...
 
Easy listening music is OK to me, but I think the DKV is just capable
of more than those beautiful musics of the past...
