Disklavier

In truth the volume on a DKV is a voltage limiter and not a volume control 
like on a stereo.  The exception is the volume that comes thru the speakers 
on the MarkIII, or thru the Silent Mode, which is audio anyway.

This is not a Yamaha problem.  MIDI is a set of standards and the Disklavier 
is a MIDI player.  So is PianoDisc and the QRS Pianomation system.  All 
modern day electronic player pianos are driven by solenoids placed under the 
back of the keys.  There must be a minimum voltage be make these solenoids 
fire. Choking this voltage tends to make the system overheat. Piano actions 
are mechanically driven, so the voltage pulsing through the solenoid 
ultimately determines how hard the key is activated.

A MIDI velocity value has no friction taken into the calculation.  It is an 
electronic measurement translated into data that plays your piano.  Buying 
PianoSoft, PianoDisc or QRS music for your player piano guarantees that this 
data is safe to play on your DKV.  The velocity data on these disks is 
between 64(QRS) and 100 (Yamaha).  Therefore, Yamaha has already built 
controls into this system if you buy their music or record your own on your 
Disklavier.

As a piano owner, you are responsible for the data you download off the 
internet to put into your piano.  No piano manufacturer could possibly have 
control over data generated by a teenager with an electronic keyboard!  Use 
the veloset program to make sure none of the numbers goes over 90.
