The ability to play back at low volume on a piano player system is limited in part by the mechanical nature of the instrument, where the solenoids have to overcome the inertia and keep control of the solenoids (i.e keys, whippen, hammers, etc.) The other factor is the sophistication of the electronics, i.e. how accurately the key and hammer movements are monitored and how accurately the solenoids are controlled. On the Disklavier, the key & hammer sensors, as well as the solenoids are (obviously) built into the piano, not the DKV controller. The processing of the sensor information, as well as the fine control of the solenoids is handled by the PK-control circuit board. This is also built into the piano, which means that factors such as the lowest ppp volume cannot be changed by anything in the DKV controller. Basically, the DKV unit is a user interface which sends MIDI information to the piano and MIDI information cannot alter the characteristics of the hardware it is sent to.
If you think of an analogy, no matter how many DVD players, speakers or other gadgets you put into your car, you're not going to make it any faster, but you might enjoy the gadets so much, you don't worry about how fast you go.
