Vel Scale and Vel Offset have a very close relationship; when you change the value of one of
them, youÕll often want to change the value of the other as well. For example, suppose you set
Vel Scale to 250% in a zone, to make it stand out from the other zones when youÕre playing hard.
You may Þnd that the velocity curve pins at the high end rather quicklyÑin other words, by the
time youÕre playing Ä, the Þnal attack-velocity value may already be 127, and playing ÄÄ or ÄÄÄ
doesnÕt give you any more dynamics. Setting a negative offset shifts the velocity curve
downward, preventing the Þnal attack-velocity value from maxing out before you get to ÄÄÄ.
HereÕs 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 Þnd that all the Þnal 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.
