Attack Time
This parameter determines the time required to reach the Break Level (see below) value.
You may use the Filter Attack Curve Form node parameters to alter the shape of the Filter
Attack curve.
The combined total of the Filter Attack and Decay Time parameters is equal to the total
length of the (synthesized or sampled) Impulse Response (determined by the Length
parameter, see “Length” on page 122), unless the Decay time is reduced.
Break Level
This parameter determines the maximum filter cutoff frequency, the envelope reaches.
It also acts as the break point between the attack and decay phases of the overall filter
envelope. In other words, when this level has been reached after the Attack phase, the
Decay phase will begin.
Note: You can create interesting filter sweeps by setting the Break Level to a value lower
than that of the Init Level.
Decay Time
Determines the time required (after the Break Level point) to reach the End Level value.
You may use the Filter Decay Curve Form node parameters to alter the shape of the Filter
Decay curve.
The combined total of the Filter Attack and Decay Time parameters is equal to the total
length of the Impulse Response file (determined by the Length parameter, see “Length”
on page 122), unless the Decay time is reduced.
