To have delegate pitch considered for motion synthesis, turn on Use Pitch, choose Range or Unique, and then make the appropriate settings.

Pitch is determined by the angle in degrees of the delegate about the world X-axis. In world coordinates, the delegate's pitch is positive when it's aimed upward, negative when it's aimed downward, and 0 when it's aimed parallel to the home grid.
Interface
- Use Pitch
-
Turn on to have the motion synthesis engine consider delegate pitch in determining whether to activate the state.
Range group
When you choose Range, the motion synthesis engine activates the clip when the delegate's pitch falls inside the specified range.
- Min/Avg/Max display
-
After you synthesize the Master Motion Clips, displays delegates' minimum, average, and maximum pitch.
- Min
-
Set a minimum pitch for the range.
- Max
-
Set a maximum pitch for the range.
Unique group
When you choose Unique, the motion synthesis engine activates the clip when the delegate's pitch matches a specific value, optionally with a rising, falling, or constant value before or after the specified value.
- Value
-
Set a unique pitch value
- In and Out groups
-
These radio buttons let you specify the behavior of the parameter before and after the unique value is met.
- Anything Pitch before or after the target value is not relevant.
- Decreasing Pitch decreases before or after it reaches the target value.
- Constant Pitch before or after the target value is constant.
- Increasing Pitch increases before or after it reaches the target value.
Scale Pitch Orientation group
These settings let you scale the pitch at which the animation is played, depending upon the pitch of the delegate. By default, when Scale Pitch is off, the animated object will pitch normally. If you turn it on, you can then set a Base Pitch at which the animation should play, plus a percentage to specify how much the Base Pitch is modified by the actual delegate pitch. If the Percentage is 100, then only the Base Pitch will be used; anything else will scale between the base pitch and the delegate pitch. This is useful for when birds and other objects elevate, but don’t pitch up.
- Scale Animation
-
Scales the clip's pitch based on delegate pitch.
- Percentage
-
Specify how much to alter the pitch based upon the difference between the delegate's pitch and the Base Pitch setting.
The formula used is this:
Pitch change % = (current pitch/Base Pitch – 1) x Percentage %
- Base Pitch
-
Specifies the delegate pitch at which the animation should be played back at its normal rate.
Scale Playback Speed group
These settings let you scale the rate at which the animation is played, depending upon the pitch of the delegate. By default, when Scale Animation is off, the object animation will always play at its normal rate. If you turn it on, you can then set a Base Pitch, at which the animation should play at its normal rate, plus a percentage to specify how much the animation rate is modified by the actual delegate pitch.
- Scale Animation
-
Scales the clip's animation based on pitch.
- Percentage
-
Specify how much to alter the playback speed based upon the difference between the delegate's pitch and the Base Pitch setting.
The formula used is this:
Animation Speed change % = (current speed/Base Pitch – 1) x Percentage %
For example, if a delegate's pitch velocity is 50 percent above its base pitch rate, and the Scale Percentage value is 50, then the playback speed is scaled up by 25 percent.
- Base Pitch
-
Specifies the delegate pitch at which the animation should be played back at its normal rate.
