Disklavier

I thought I replied to this message this morning, but I must have hit the 
wrong button.  Please excuse if this reply comes across twice.

On Yamaha "silent" pianos, the sounds you hear coming from the headphones 
are coming from a different tone generator than the sounds you hear coming 
from the speakers.  The silent pianos use an MN board with the audio jacks, 
and the speakers are outputting tones from the XG daughter board inside the 
control panel.  On Disklavier Pros, there is a switch to toggle back and 
forth these soundcards.

Also, on the silent pianos, there is a rail installed to keep the hammers 
from hitting the strings.  In order to have the keys on the keyboard still 
feel the same using the silent mode, Yamaha has installed special piano 
action parts (jacks with an extra nub) to accomplish this special "let-off" 
adjustment.

However, I think that it might be possible to make a regular Disklavier play 
in silent mode if you did the following:

1) install a rail to keep the hammers from hitting the strings.  Keep in 
mind that the let-off adjustment would be tricky and probably not as nice to 
the touch as a Yamaha factory install.  The rails are available from 
third-party vendors.

2)  you would have to put the Disklavier in "record" mode and select another 
instrument using the voices button.

3)  connect a speaker with a headphone jack or an amplied set of headphones 
(if there are such things) to the audio output on the rear of the control 
box.  I don't know if such things exist.

or

4) connect a computer to the disklavier, using appropriate MIDI interfaces 
and software, and connect headphones to the computer sound card.

However, I think the best idea, if you really, really need the Silent 
function, is to trade in your Disklavier for a model that has this feature 
already built into it!
