+++RW: The Disklavier's dynamic range, the sound power between the
softest and loudest notes reproduced is limited, of course, by the range
through which the solenoids are driven. Those limits of sound power
remain fixed regardless of the note velocities in the file. What can be
varied is the DKV's Volume Control.
With the Volume Control set at "0", you will hear uniform gradations in
sound power as note velocities progress from about 20 to 95. Notes at
velocities from 95 to 127 will play with the same loudness as 95. In
other words, at DKV Volume = "0", loudness starts limiting at a velocity
of 95.
If you set the DKV Volume Control to "-3", limiting begins at about
velocity 113; at "-4", 125. At DKV Volume Control to "-5", a note of
velocity 127 begins to limit. Throughout the range of the DKV volume
control, the response curve pivots at velocity 22. In other words,
notes at velocity 22 play at the same loudness regardless of the Volume
Control setting. This all much easier to visualize graphically.
To answer your question, you may utilize the full dynamic range of the
DKV by keeping your note velocities in the range of 20 to 95 and the DKV
Volume at "0". If you scale-down the velocities further, you will
reduce the dynamic range. If your file does have velocities greater
than 95, you may be able to reduce the DKV volume to avoid limiting the
velocities above 95, but you will still reduce the gradations among the
lower velocity notes and, thus, reduce the dynamic range. There is no
free lunch.

+++ RW: On/off pedaling tends to "clunk-clunk" on the DKV--which is OK
for some people, I guess. Some of Yamaha's early PianoSoft diskettes
had only on/off pedaling and that seemed acceptable a few years back.

+++ RW: DKV-formatted floppies are "sort of like" DOS. I don't know the
details. I use the Giebler Utilities (www.giebler.com) to tunnel back
and forth and so have I have had no need to know.
I have "worked over" MIDI files. It's lots of work and a good
illustration of the law of diminishing returns.
