Velocity Scale (VelScale)

This lets you amplify or diminish velocity response. Normal response is 100%. Higher values
make the keyboard more sensitive (you donÕt need to play as hard to get higher MIDI velocities)
while lower values make it less sensitive (playing harder doesnÕt change MIDI velocity as
much). You can also set the scale to a negative number, in which case the velocity response is
turned upside-down: playing harder produces a softer sound and vice versa. This is useful for
creating velocity-based crossfades between zones. See the following section on Velocity Offset
for ideas about negative scaling.
The following illustration shows what happens when you change Velocity Scale. Note that
Velocity Scale is the only parameter changed in this example; the other parameters are set to
their defaults (offset = 0, curve = linear, min = 1, max = 127).

Velocity Offset

VelOffset also changes the response, but in a more direct way, by adding or subtracting a
constant to the key velocity. For example, if this is set to 25 (assuming a scale of 100%), then 25 is
added to the velocity of every keystroke, usually making the sound that much louder. The
softest possible keystroke will have a value of 25, while a keystroke with velocity of 102 will
produce the same sound as a note with velocity 127 (102+25=127). Negative values diminish the
response: a setting of -25 means the loudest velocity available will be 102, while any keystroke
25 or below will produce a velocity of 1 (a velocity value of zero has a special meaning in MIDI
and cannot be used for Note Ons).
You can think of Scale as being a proportional change to the velocity, while Offset is a linear
change. The maximum values for Offset are ±127. The following illustration shows the effects of

Strike Velocity
Velocity Scale: 100%
as you strike the keys harder (increase the
velocity) MIDI velocity increases proportionally
Velocity Scale: 200%
MIDI velocity reaches maximum on
medium strike velocity
Velocity Scale: 50%
MIDI velocity never reaches maximum, even on
maximum strike velocity
