Velocity Curve (Vel Curve) - Kurzweil PC1 - MUSICIANS GUIDE REV B Manual

Here's another example: reversing a linear velocity curve so that it plays loud when you strike
the keys softly, and vice versa. You might think that all you have to do is set Vel Scale to -100%.
When you do that, you find that all the final attack-velocity values are at minimum. When you
set Vel Offset to 127, the velocity curve gets shifted as high as it will go, enabling the negative
scaling to work properly, as shown in the following graph.

Velocity Curve (Vel Curve)

So far we've been describing the velocity parameters in terms of linear velocity curves--that is, the
final attack-velocity increases at a uniform rate as your keystrike velocity increases so that on the
graph, the velocity curve appears as a straight line. You can use the Vel Curve parameter to
change the shape of the velocity curve, which provides variations in dynamic response.
The setting for Vel Curve in all zones of the default setup is Linear. There are two other values
whose effects are the opposite of each other. Sin+ causes the final attack-velocity value to increase
faster than the linear curve until your keystrike velocity is mf, than slower than the linear curve
as keystrike velocity continues to increase (the velocity curve resembles the first portion of a sine
wave, if you're wondering why the value is called Sin+). Cos+ causes the final attack-velocity
value to increase slower than the linear curve until your keystrike velocity is mf, than faster than
the linear curve as keystrike velocity continues to increase (resembling the first portion of a
cosine wave).
