Velocity Offset (VelOffset)
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
Velocity Offset. Note that Velocity Offset is the only parameter changed in this example; the
other parameters are set to their defaults (scale = 100%, curve = linear, min = 1, max = 127).
