I imagine he is referring to the wind system, which for this organ is entirely Jiri Zurek's invention. As JZ mentions in his notes on the sample set, the actual Rotterdam Marcussen organ has rock solid stable wind, so for the purposes of the sample set he has created a wind model entirely of his own invention, which employs 11 wedge-bellows to create a "lively" (his word) result. To mimic the behavior of the actual real Rotterdam organ itself, the wind model should be turned off, however. (Those of us in the USA don't have the choice of using it anyway.)
