Envelope Generator Component

The Envelope Generator creates a series of control levels with which you can control another component's control(s), typically a gain type control, to travel through the series of levels that define the envelope. For example, you can cause the gain of a component to go immediately from -100 dB to the Release Level of -20 dB then to the Attack Level of 10 dB in 3 seconds, then fall to the Sustain Level of 0 dB in 5 seconds where it stays for 10 seconds, then goes back to the Release Level of -20 dB in 2 seconds, then immediately back to -100 dB. All of the times and levels are adjustable.

Key

Engaging this toggle button causes the output level to go from the Release Level to the Attack Level, then to the Sustain Level where it is held until this button is released. When released, the output level goes from the Sustain Level to the Release Level, then to -100 dB. All the time settings are observed for all levels.

Trigger

Clicking this trigger button starts the envelope running through one complete cycle.

Function

Default/Range

Attack Level

(dBFS)

The first level of the envelope. The output level rises or falls from the Release Level setting to the Attack Level setting.

Prior to starting the envelope, the output level is at -100 dB, when the envelope is started, the output immediately goes to the Release Level setting then starts moving towards the Attack Level setting.

Default = 0

Range = -100 to 20

Attack Time

(seconds)

The time it takes for the output level to reach the Attack Level from the Release Level.

Default = 1

Range = 0.03 to 10

Decay Time

(seconds)

The time it takes for the output level to reach the Sustain Level from the Attack Level.

Default = 1

Range = 0.03 to 10

Sustain Level

(dBFS)

The output level is sustained at this level for the time set in Sustain Time.

Default = -6

Range = -100 to 20

Sustain Time (seconds)

The length of time the output level is kept at the Sustain Level.

Default = 1

Range = 0.03 to 10

Release Level

(dBFS)

The last level of the envelope. The level at which the envelope is released at the end of its cycle. After the envelope reaches this level, the output immediately goes to -100 dB.

Default = -40

Range = -100 to 20

Release Time (seconds)

The time it takes for the output level to rise or fall from the Sustain Level to the Release Level.

Default = 1

Range = 0.03 to 10
