Linen | SuperCollider 3.12.2 Help

Class Methods

Linen.kr(gate: 1.0, attackTime: 0.01, susLevel: 1.0, releaseTime: 1.0, doneAction: 0)

Arguments:

gate	This triggers the envelope and holds it open while > 0. If gate < 0, force release with time `-1.0 - gate`. See EnvGen: Forced release.
attackTime	The duration of the attack portion.
susLevel	The level of the sustain portion.
releaseTime	The duration of the release portion.
doneAction	An integer representing an action to be executed when the envelope is finished. See Done for more detail.
