Parameters

input

Control Type Has Sub-chain? Sub-chain Parameters Behavior
Threshold no threshold (-1 to 1) gate


This parameter gives you access to the threshold level of the input comparator used to detect the rising and falling edges of your incoming gate signal. There is also a button for manually firing gates.

attack

Control Type Has Sub-chain? Sub-chain Parameters Fader Scale
Gain/Bias yes gain (-10 to 10)

bias (0s to 99s)

time in seconds


This parameter sets the (maximum) amount of time it takes for the envelope to ramp up to a value of 1 when it receives a gate signal. The attack portion of the envelope is triggered by a rising edge at the unit input.

decay

Control Type Has Sub-chain? Sub-chain Parameters Fader Scale
Gain/Bias yes gain (-10 to 10)

bias (0s to 99s)

time in seconds


This parameter sets the (maximum) amount of time it takes for the envelope to decay from 1 to the sustain level.

sustain

Control Type Has Sub-chain? Sub-chain Parameters Fader Scale
Gain/Bias yes gain (-10 to 10)

bias (0 to 1)

linear


This parameter sets the amplitude of the sustain portion of the envelope. The decay stage ends at this level and the release stage begins at this level.

release

Control Type Has Sub-chain? Sub-chain Parameters Fader Scale
Gain/Bias yes gain (-10 to 10)

bias (0s to 99s)

time in seconds


This parameter sets the time it takes for the envelope to fall back to zero. The release portion of the envelope is triggered by a falling edge detected at the unit input.
