Disklavier

Hi and Happy New Year to you all,

I'm new on this list so I will start by introducing myself. I'm a french
musician and singer working with guitars and synthesizers. I work in a
Pub in the city of Toulouse which owns a Disklavier. It's great for me
to play on such an instrument but no document can be found and I'm
facing some problems...

Can somebody tell me the age of this instrument ? It's a black bright
piano and the disk module is integrated in the top (not upon it). There
are only 5 or 6 buttons and a display on the right of the drive and the
words below them are in japanese, the display too ! Midi in and out are
below the keyboard, on the right side.

Playing a disk is OK and I have a Midi signal at the Midi out, but I
can't control my expanders from the piano keyboard. My aim is to add
some strings pads to the piano sound and to control the volume of the
strings with a FC7 control pedal plugged in my MCS2. Do you think it's
possible ?

Thank you and best regards.
