java.lang.Object

com.jsyn.unitgen.UnitGenerator

com.jsyn.unitgen.UnitGate

com.jsyn.unitgen.EnvelopeAttackDecay

All Implemented Interfaces:

UnitSource

public class EnvelopeAttackDecay
extends UnitGate

Two stage Attack/Decay envelope that is triggered by an input level greater than THRESHOLD. This does not sustain.
