TYPE: CHOP
TITLE: Lag CHOP

This CHOP adds lag and overshoot to channels. It can also limit the velocity
and acceleration of channels. Lag is an effect that slows down rapid changes
in the input channels. Overshoot amplifies the changes in the input channels.

Two values exist for each parameter. For example, in the Lag effect, when
the input channel value is rising, the first lag parameter is used, and
when the channel value is decreasing, the second lag parameter is used. This
can give a quick rise, and a slow fall. But lag up and down are often kept
at the same value.

This CHOP may be time sliced by enabling the Time Slice flag in the Common
page. It can also take advantage of Minimal Time Slice Cooks in time slice 
mode (see the Time Slice Preferences dialog in the Options menu).

The Spring CHOP has some similar effects.

Parameters
    Method             - The method by which lag is applied to the channels.
        Lag Value     - Up is defined as an increase in values
                         of the input channels, and down is a 
                         decrease in values of the inputs.
        Lag Amplitude - Up is defined as an increase in amplitude
                         (moving away from zero) and down is
                         defined as a decrease in amplitude (moving
                         towards zero) of each input channel.
        Lag Magnitude - All the input channels are treated as
                         components of one vector, and each
                         operation is applied to the vector as
                         a whole. Only the first parameter in
                         Lag, Overshoot, Clamp Slope and Clamp
                         Acceleration applies in this mode.

    Lag                - Applies a lag to a channel. The             /lag1
                         first value is for lagging up, and          /lag2
                         the second is for lagging down. It is
                         approximately the time that the output
                         follows 90% of a change to the input.
    Overshoot          - Applies overshoot to a channel. The         /overshoot1
                         first value is for overshoot while          /overshoot2
                         moving up, and the second is for
                         overshoot while moving down.
    Clamp Slope        - Clamps the slope (or velocity) to lie
                         between the values listed in "Max Slope"
                         below. Slope is expressed as value/Units.
    Max Slope          - The first value limits the slope when       /slope1
                         it is rising, and the second value          /slope2 
                         limits the slope when it is decreasing.
    Clamp Acceleration - Clamps the acceleration to lie between the
                         values listed in "Max Acceleration" below.
                         Acceleration is expressed as value/(Units*2)
    Max Acceleration   - The first value limits the acceleration     /accel1
                         when it is rising, and the second value     /accel2 
                         limits the acceleration when it is decreasing.

Local Variables
    I   - The current index.
    C   - The current channel (0 to NC-1).
    NC  - The total number of channels.
