• (Parameter) max: One or more sliders that become available when the Apply Link pop-
up menu is set to “Source value below maximum,” “Source value between min and max,”
or “Source value outside min and max.” A “max” slider appears for each component of
the source parameter. Adjusting this slider defines a maximum value to limit when the
link behavior is active.
Logarithmic behavior in Motion
The Logarithmic behavior is the inverse of the Exponential behavior. Like the Exponential
behavior, it creates more natural animations when scaling objects, especially when using
high values. The Logarithmic parameter behavior applies a mathematical function to create
a logarithmic curve (rather than linear) between the two values—the effect ramps up
quickly, and then the effect slows down. This allows the animation to progress slowly when
the scale values are small and speed up when the scale values are large. When applied to
parameters other than Scale, the Logarithmic parameter behavior creates more organic
animations than other interpolation modes.
The Logarithmic behavior can be applied to parameters animated with behaviors or
keyframes; however, Logarithmic does not affect the parameter unless the Start Values or
End Values are nonzero.
Note: You can also change the interpolation modes of keyframes to Logarithmic. See Set
curve interpolation in Motion.
Adjust this behavior using the controls in the Behaviors Inspector:
• Start Value: A slider that sets the value added to the parameter at the first frame of the
Logarithmic behavior.
• End Value: A slider that sets the value of the Logarithmic behavior at the last frame.
Over the life of the behavior, the parameter that the Logarithmic behavior is applied to
makes a transition from the Start Value to the End Value, plus the original value.
• Start Offset: A slider that delays the beginning of the behavior’s effect relative to the
first frame of its position in the Timeline, in frames. Adjust this parameter to make the
behavior start later.
• End Offset: A slider that offsets the end of the behavior’s effect relative to the last
frame of its position in the Timeline, in frames. Adjust this parameter to make the
behavior stop before the end of the behavior bar in the Timeline. Using this slider to
stop the effect, instead of trimming the end of the behavior bar in the Timeline, freezes
the end of the effect for the remaining duration of the object. Trimming the end of the
behavior bar resets the object to its original parameter.
• Apply To: A pop-up menu that shows the parameter affected, and that can be used to
reassign the behavior to another parameter.
MIDI behavior in Motion
The MIDI behavior lets you edit and animate object parameters using standard MIDI
devices, such as a synthesizer. For the true motion graphics mixmaster.
Adjust this behavior using the controls in the Behaviors Inspector:
• Control Type: A pop-up menu that sets the mode of the MIDI controller. There are three
modes:
• Note: Use this mode when the control is a keyboard key on the MIDI device.
