Curve (Curv); Entry (Ent) And Exit Values - Kurzweil K2600 Musician's Manual

Curve (Curv)

This lets you taper the controller response. The default setting is Linear, which means that the
response follows a straight line as you move the controller.
Expand produces a curve that is less steep than the linear curve at keystrike velocities below 64,
and steeper than the linear curve at keystrike velocities above 64. In other words, when youÕre
playing softly, youÕll notice velocity differences less than with a linear curve, while when youÕre
playing hard, youÕll notice velocity differences more.
Compress produces a velocity curve that is the opposite of the expanded curveÑthat is, youÕll
notice velocity differences more when youÕre playing softly than when youÕre playing hard.
Crossfade (Xfade) is designed to be used in tandem with the Reverse Crossfade curve, enabling
you to perform smooth crossfades between different programs.
Bump tapers velocity response to resemble a bell-curve, making its response greatest at medium
strike velocity, and progressively weaker as strike velocity increases or diminishes. If you start
playing softly, then progressively louder, the response will increase from 1 to 64; if you keep
playing harder, the sound will get softer.
The next Þve curves are Reverse Linear (rLin), Reverse Expand (rExp), Reverse Compress
(rCmp), Reverse Crossfade (rXfd), and Reverse Bump (rBmp). These taper controller response
in reverse of the Þrst Þve curves. For example, Reverse LinearÕs response is such that moving
the pitch wheel forward decrease pitch, moving it back will increase pitch, and so on. As with
velocity, the reverse curves offer you a quick way to achieve negative scaling of physical
controller response.
To get an idea of how these curves affect controller response, refer to the Velocity Curve charts,
which begin on page 7-14.

Entry (Ent) and Exit Values

Entry value allows you to specify an initial value for a controller in a setup that will be sent
whenever you select that setup. For example, if you want to make sure that all of the modulation
in a zone is turned off when you select a setup, assign a physical controller to a destination of
MIDI 01 (MWheel) and set Entry Value to 0.
Entry values ignore the current position of the physical controller when the setup is selected. In
fact, if the physical controller is above or below the entry value when the setup is selected
(which it often is), moving the controller will have no effect until it is past its entry value. In the
modulation example above, moving the assigned controller wonÕt turn on any modulation until
itÕs pushed all the way down, and then up again.
An entry value of None is quite different from a value of 0. None means that there will be no
initial controller command when the setup is selected, and any subsequent movement of the
physical controller will be effective.
Exit Value tells the K2600 to send a value for that controller whenever you leave the setup, either
by selecting another setup or by selecting a different mode altogether. It can be very useful when
a controller is doing something to the sound, and you donÕt want that effect to continue after
you leave the setup. For example, if you want to make sure a zoneÕs pitch returns to normal
whenever you leave a setup, you would set Exit Value to 64 for any controller whose Destination
parameter is set to BendUp. Again, None means no command is sent.
