Disklavier

I was seduced by the disklavier DU1A (a Mark II system)  when I saw this :

/"One of the season's most remarkable new ideas is PianoSmart^(TM) 
technology, now featured on all Mark III Series pianos. This new system 
enables the Disklavier to play along with standard audio CDs, matching 
the playback of the commercial audio track with accompanying MIDI files 
and synchronizing them automatically. //Owners can even record their own 
piano accompaniments to their favorite CDs, and the PianoSmart 
technology will synch them perfectly on playback."

I still want to try this, but the manuals give no clue as how to do this.
And Yamaha does not speak...

What about this :

*PianoSmart^(TM)* A truly revolutionary breakthrough in Disklavier 
technology, the PianoSmart system opens up a world of additional ways to 
enjoy your digital/acoustic piano. PianoSmart intelligently synchronizes 
Disklavier recording and playback with the operation of the built-in CD 
player. What this means in real terms is that you can now record your 
own piano or electronic instrumental tracks while listening to your 
favorite CDs, and play them back in perfect combination with the 
original recordings. 'Sit in' with the hottest new groups, classic 
combos or a full symphony orchestra, then sit back, press a couple of 
buttons, and listen to yourself performing 'live' with the pros! Through 
the use of MTC (MIDI Time Code), PianoSmart can also synchronize 
recording and playback with external devices such as multi-track 
recording equipment and video cameras*. These features enable pianists, 
families and educators to create audiovisual records of any performance, 
complete with 'live' Disklavier acoustic piano playback, stereo audio 
instrumentals and vocals, and full-motion video--all as one integrated 
presentation. They also allow creative musicians *(1)* to collaborate in 
ways seldom dreamed of before. In combination with the many other 
Disklavier capabilities, PianoSmart extends digital/acoustic creativity 
into a whole new universe of options. *Video synchronization requires an 
external video MIDI sync interface.

*(1) *Still no clue, though...

... and if Carol and PianoBench or the other nice experts on the list do 
not know, who will ?
