Velocity Curve (Vel Curve)
So far weÕve been describing the velocity parameters in terms of linear velocity curvesÑthat is,
the Þnal 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 Þnal attack-velocity value to
increase faster than the linear curve until your keystrike velocity is mÄ, than slower than the
linear curve as keystrike velocity continues to increase (the velocity curve resembles the Þrst
portion of a sine wave, if youÕre wondering why the value is called Sin+). Cos+ causes the Þnal
attack-velocity value to increase slower than the linear curve until your keystrike velocity is mÄ,
than faster than the linear curve as keystrike velocity continues to increase (resembling the Þrst
portion of a cosine wave).

Keystrike Velocity
Minimum Velocity (Min) and Maximum Velocity (Max)
These parameters work in tandem to deÞne the velocity range for the zone. If the Þnal attack-
velocity value of a note is below the minimum or above the maximum, the note wonÕt sound.
Note that itÕs not your keystrike velocity that determines whether the note sounds, but your
keystrike velocity plus (or minus) the adjustments applied by the other velocity parameters.
In the default setup, these parameters are set to values of 1 and 127 for all zones. Intuitive entry
works nicely for editing: hold down the Enter button, and strike any key. Your keystrike
velocity sets the value.
You can also set the value of the Min parameter higher than the value of the Max parameter for
any zone. In this case, the zone plays outside the velocity rangeÑthat is, youÕll hear notes when
the Þnal attack-velocity value is below the minimum or above the maximum. Þnal attack-
velocity values within the velocity range donÕt produce notes.
