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...

I have seen Disklaviers used in theatre work.  Your singer could play a few
notes, then the Disklavier could be controlled remotely through a MIDI
connection. It worked at the Kennedy Center.  Or you could just hide the
remote control where she could press Play and start the accompaniment
instead of a key that "shows up".  For some silly reason, I don't think
Yamaha is being secretive - it's just knowing who to ask.  Most Disklavier
technicians and salespeople don't even know what sysex codes are. Maybe
PianoBench could help you to make your own SmartKey arrangements as he
probably knows more about Yamaha MIDI than anyone else.

BTW, neither Maintenance Mode or Test Mode are no big secrets to access.
The only reason they aren't included in your owner's manual is that if you
press the wrong button  you can put the piano into the wrong language or
worse yet, tell your DKV it is the wrong model and nothing would play right!
Like most mechanical things you buy, these modes really don't have any
"user" functions.

Until you find your sysex codes, why don't you explore some of the other
capabilities of the DKV like remote access, time-delayed start, the foot
pedal switch, etc.  With MIDI, there is usually more than one way to do
things!  Meanwhile, good luck and Happy New Year!

You are right, and that' what we do now. One of the problems left, as
far as "Le piano de Nanette" is concerned, is that we sometimes have
to use a very long cable (some 120 feet long...) going from from the
DKV control box that our sound and light tech  manipulates, to the
stage. Most of the time we do not need that length, so we use a 60
feet cable, and  add another 60 feet cable whenever necessary. But
during the rehearsal we've had a few problems, with the control box
suddenly going crazy, off and on, and I still fear itmight happen in a
performance. I could not use a midi cable with "amplifiers" because
the control box is a very good tool to control the DKV (Hurrah Yamaha
!), an I did not want to tour with a computer this time.

I guess that's my problem...  I kept asking to the wrong people I am
afraid. And Yamaha Europe is in Belgium, they simply do not have a web
site...

I've been into computer music for quite a while, and composed music on
synthesizer for some 50 theatre productions here. Then 10 years ago I
stopped doing that because I was tired of  computers pretending to be
violins... <G>  Then when I had the opportunity to buy a DKV, I  was
so happy : I could have the best of both worlds !
Now I must admit that in ten years, one loses tracks in computer
music. The new  concepts in sequencer programming - like object
programming - are quite difficult  for me to deal with. I was in a
hurry and  did my best to make music, using very simple tools (my
hands as one, excuse me as two... ;-) ) leaving the  computer tasks
for a more relaxed atmosphere. I will do that now !
I guess the smartkey system is not THAT complicated. I can think of
ways to do the job without using it. But  I am thrilled by the idea of
giving the actors a way to decide themselves when the music comes in.
I hate to tell the actors that they are free to improvise onstage,
within limits of course, then tell them that, as soon as the music
comes in, controlled by the sound tech, they will have to obey it and
transform themselves into CD-player-controlled-robots. The DKV was, to
me, a first step in liberating the actor from that point of view... I
see now that I am still a few steps behind ! But I like it, anyway.
(and I am even further away from getting enough money to buy me a live
orchestra, which would be heaven !)

Fortunately,  Jorge Fernandez sent me -and the group-  the address of
 Yamaha UK site, full of very interesting links about Midi and the XG
format tutors. I am still searching through it all, and hope I will
find what I need.

I totally agree with you. I sometimes use the "auto calibrating
function" (not sure of the name, because the piano is actually on
tour, and I do not have an access to it).  I guess it might be useful
 because of the number of moves the piano endures, bravely and almost
without complaints...  It's a pretty good, pretty solid piano !

I am afraid ther's no pedal switch on the DU1A. The remote control
will not do as the tech undestandably  insists on knowing the title
(or  number) of the music he's gonna cue in.   The Cue Time and
Smartkey systems seemed to be very good answers to my problems, but I
lack the precise informations on how to use them. For example,
regarding cue-time, I would love to design a simple electro-mechanical
device -like a barrel organ of some sort- to let an actor control the
tempo of the music played by the DKV. I made a prototype of that for
use with a midi sequencer, controlling the SMPTE code, some 10 years
ago, but then I stopped using synthesizers and samplers, it's all in
my attic now.  I would love to have that on my DKV, but I am not sure
I could bring the old Atari computers I used then, back to life ! <G>

Which brings me even more choices to wander through !

Thank you, Carol
I really appreciate your dedication and  answers to the group !

As a matter of fact it does in my case. My mother's name is Annette,
and her grandchildren call  her Nanette. She was a great pianist -to
my ears at least !-  and when my daugther decided  to stop  playing
piano,  I was a very sad father. And this is the story behind "le
Piano de Nanette", although  I disguised it quite a bit.  But the play
is a tribute to my mother, the Great Nanette. She decided to stop
playing piano onstage at the age of 19, after having missed the last
chord of some tricky Lizt piano competition tune by a whole key ! 
And, again, I agree  with you : Nanette is a very special name, and
probably does not apply to every Granny  in the world ! ;-)))
I will think it all over when the text will be translated in English,
probably in the next few months ! I've sent a couple of  photographs
of the play on this group website, by the way.
