Disklavier

In posting my reply above, it made me think about the functionality 
of my piano that I had questions about.

I have a C2 grand with the disklavier and silent system.  It has 
always seemed strange the way the silent system functions, here's 
what happens.

I turn on the disklavier and press the button on the silent system.  
There is a brief humm while the silent bar moves into position.

Now here is the strange part.

If I just start playing the piano, the sythesized piano sounds come 
out of the speaker under the piano.  Every time I want to use the 
silent system I have to climb under the piano and shut off the 
speaker (otherwise it kind of defeats the purpose of the "silent" 
system).

Could this actually be the way Yamaha designed this system?

I've lived with this for about 3 1/2 years now and every time I climb 
under the piano I try to think of a new way to torture the Yamaha 
technician that couldn't get the speaker to shut off when the silent 
system is on (arrggh).

Is there something I am missing?  Does everyone's silent disklavier 
function this way?

just wondering.
