Disklavier

Hi Geoff,

I don't think DKVBrowser has anything to do with this.  My best guess is that the songs that you are playing when using DKVBrowser are somehow exercising the pedals quite a bit more than the songs that you normally play from your laptop.  If this is a reproducible situation, you might want to try moving some of the songs from your laptop to the piano's "From-To-PC" folder, and then play them from DKVBrowser.  You should experience the same pedal-failure rate as playing from your laptop directly.  (I think the demo songs on the MarkIV are marked as "don't copy", so you probably can't do the reverse.)

You also said that you play your files from your laptop "wirelessly via USB".  I'm confused.  I assume you mean that you are playing MIDI files (using what player?) via USB, but the wireless part has me intrigued.

Anyway, for further conversations on DKVBrowser, I run a yahoo group dedicated to the software over here:

Enjoy!
-Kevin

Hi Bill
 
Thanks for your detailed reply.
 
I have carried out the tasks you set and
the pedals worked flawlessly.  
 
The piano in 9 months old –
purchased March 2013 from a Yamaha Australia dealer.  The serial no. is
6338593.  I would be interested to know when it was manufactured.
The problem only occurred yesterday when I
was playing around with DKVBrowser.  After the comment in these pages “The
best software since the dawn of time”, I thought I should check it out
some more.  The only files I played were those demo and sample files which
came with the DKV (I retain all my music files on a laptop which I connect to
the DKV wirelessly via USB).  In doing that the pedals stopped working 3
times.  The first time I completely powered down and fixed it.  The 2nd and 3rd times, going to standby was sufficient.
The piano has the latest operating system
and was calibrated when new. I think the pedal problem I experienced yesterday
will remain a mystery.
 
Another question, if I may:  How
often should a full keyboard calibration be done?  I have the full service
manual and have previously done a full calibration myself.
 
Kind regards
 
Geoff

Hi Geoff,
 
I am sorry to hear about the problems you explained in your email. If
your pedals are failing as often as you say, then you have a hardware problem.
Having your pedals quit 3 times an hour is NOT the norm with the Disklavier
Mark IV and is a problem that needs to be corrected. The problem I described in
an earlier post is something that occurs after leaving the Disklavier on for
long periods of time (typically longer than 2 weeks.) This problem is corrected
by doing a complete power down, disconnecting it from power and letting it
"rest" for 30 minutes or more. Through the years of Mark IV
production, this problem was pretty much solved, but not totally eliminated. I
have found that if I go through this power down procedure about once a week,
then I never have a pedal playback problem.
 
Lets troubleshoot this a little bit. How old is your piano? If you are
not sure, give me the serial number of the piano (a seven digit number on the
plate or harp) located under the treble end of the music desk. How long has this
problem been happening? Have you reported this problem to Yamaha? If so, what
was recommended and what was the result? When was the last time you had the
piano calibrated? Has your piano been updated to the latest operating system?
 
If I was there, I would try the following. Normally this is done by a
Disklavier technician, but if you are careful, you can do it yourself. Power
down the piano again and disconnect it from power. On the back side of the key
drive unit under the treble end of the piano, you will find a box that contains
the CSP (Central Signal Processor) board. There are a number of RCA connections
to this box. Disconnect and re-insert the the two connectors labeled TO I/O
BLUE and GREEN. Disconnect and re-insert the connector labeled TO PD. Go to the
I/O unit and disconnect and re-insert the BLUE and GREEN connectors located on
one end of the I/O  Center above the LAN
connector.
 
Plug the piano back into the A/C and power back up. Record a two minute
song of playing the damper pedal and shift pedal (right and left pedals),
depressing each pedal every two seconds. Then, play this song back 4 or 5
times. If the pedals continue to work, then play your music as you normally do
and see if the pedals continue playing or not.
 
Let me know the results. Hopefully, your pedal issue is solved.
 
Bill

Hi Bill
 
I also
have a Mk IV  (C3 DKV).  I experience the pedal problem often, 3
times in the space of an hour when playing files on the HDD through
DKVBrowser.  I can fix it simply by going to standby mode and on
again.  I rarely have the problem when playing midi files from my laptop
using VanBasco's Karaoke Player.
 
I power down
and turn the power off at the wall socket every night.
 
This
seems to be an identifiable and common bug affecting a lot of users - probably
every Mk IV user.  Do you know why Yamaha doesn't  put out a fix for
it?
 
Many
thanks for your knowledge, wisdom and help in these pages.
Geoff
 
Long live
