again to hide the envelopes.
The ranges of volume and pan envelopes are equivalent to the ranges of the
corresponding track controls:

 Track pan envelope: The range is from 100% Left to 100% Right pan, with Centered at
the midpoint, 0 (zero).

parameters by adding an envelope for any parameter to the envelopes for the track,
bus, or output. The envelopes are different for each type of effect. For information on
adjusting effect parameters, see “
