Piotr, you probably cannot. That said, it may be possible. It depends on
how much room there is between the bottom of the keyboard and the top of
the exhauster bellows. The PianoDisc system does hang down a bit. Contact
them for just how much drop is required. Most player bellows are pretty
snug to the bottom of the key bed.

Another requirement is how far back the bellows are at its top. The
PianoDisc system does come forward a bit as well. Again, contact PianoDisc
for measurements. Plan on making adjustments, in any case.
