3. Choose the desired Path type ( S-Linear , Linear , or Curve ). If Curve is
selected, you can use the soft knobs or data pads to change the values
for
Tension , Continuity , and Bias .
4. Add the new values to a keyframe in the effect with Insert or Modify , or
Learn. You must change the keyframe, because current work buffer
values are overwritten during the running of an effect.
5. Run the effect to see your changes.
General Curve Tips
Although adjusting the Curve path type Tension, Continuity, and Bias con-
trols can feel like a guessing game, here are some general tips to help you
build desired effects in a timely manner:
• Tension in the minus direction (up to -1.0) creates bigger, looser curves.
• Continuity at +1.0 is the same as S-Linear motion.
• Continuity in the plus direction gives a bigger bounce, with +2.0 a good
value.
• Bias in the plus direction makes the curve happen after the keyframe.
• Bias in the minus direction makes the curve happen before the key-
frame.
