Disklavier

Hi everyone, here's my problem :
I am triggering the piano from within a PC with Cubase, i am sending 
very little information at a time for example if i send only 1 Note 
On (and velocity) and a sustain pedal down message (c64 127(i've 
tried lower values like 95 to no avail)), the sustain pedal will 
randomly start clanking very fast (i'm french for lack of a better 
word the analogy would be it sounds like someone that hits their 
teeth very fast), sometimes it does it sometimes it doesnt you can 
hear the mechanical part sound when it's working right it's like a 
humm but as soon as the clanking begins you can't hear the sustain 
pedal mechanics anymore, if i look in the piano i can see the whole 
section that goes down when a sustain pedal goes down going up and 
down at a very high rate of speed about 2 times per second, it does 
it gently but still loud enough so that you can hear it.

I've tried different midi configurations with same results, i'm 
thinking this is mechanical and either part of or the motor 
controlling the pedal is damaged or there's a problem with the 
disklavier controler.

Anyone ever get this problem, is there a special midi trick to this 
or is this purely mechanical ?

also, is there any way around the 16 second note length lock on the 
piano ? i'd reall like to be able to get 20 seconds....

Thx guys
Franky.

You did not state whether you are connected to the Disklavier's MIDI 
connectors or to the "To Host" connection.

It sounds as though you are experiencing loopback.  Do you have two MIDI 
cables connected between your Disklavier and computer?  If so, 
temporarily disconnect the MIDI cable from the "Out" connector at the 
Disklavier.  If the chattering stops, loopback was the problem.

Here is how loopback occurs:

A. Your computer sends a MIDI messaage to the Disklavier's "In" connector.

B. The Disklavier returns the same message to the computer.

C. The computer returns the same message to the Disklavier, etc., etc.

Check the documentation for Cubase.  You should be able to set that 
software to NOT send back received MIDI signals.  In Cakewalk, it is 
called "Echo Mode".  If you are using the "To Host" connection, you can 
stop the chattering only by killing the software's echo mode.

I have had the same problem using Cakewalk.  When the program is 
launched, it is set by default with the "Echo Mode" in "Auto".  It needs 
to be set to "None".  It was often catching me off guard and requiring 
me to mouse through menus to turn it off. To preclude that problem, I 
built a simple switchbox that allows me to open or close either of the 
two MIDI lines.  Through forgetfulness, I still occasionally get 
chattering, but, to stop it, I need only reach over for the switch.

As for getting a 20-second note, you have probably tried to use the 
sustain pedal to accomplish that and you may not wish to have all the 
strings undamped.  That maximum note length function is surely buried in 
a control program in ROM.  It is extremely unlikely that Yamaha would 
share the code with you or burn a custom PROM.  In principle, through 
reverse engineering, that probably could be done on your own at great 
expense.

Unfortunatly, the only midi cable connected was from the midi out of 
the computer to the midi in of the disklavier so midi loopback 
shouldnt be the problem. :(

Thx for responding :)
Frank.

Does the Disklavier and pedals work properly when you play and record from a 
floppy disk?  If so, there is nothing wrong.  If the problem occurs when 
using the computer, try putting the pedal information on Channel 1 or 2.  or 
you could convert this MIDI file to Eseq file and put the pedal info on 
channel 3?

You certainly have something peculiar going on.  The next step should be 
to try to discover if the problem is within the DKV or within Cubase and 
the computer. Do you have a friend with a different computer, sequencer, 
and cable that you could substitute for yours?  Or, can you borrow some 
simple synthesizer that you could substitute for the DKV?

Have you experimented with the MIDI input settings?

Contact me privately if you need a simple MIDI test file guaranteed to 
play on a Disklavier.
