ER-301/Skewed Sine Env

Description

This AR-type envelope is generated from a single lobe of the sine wave. Instead of separate controls for attack and release which would complicate setting the duration, there is a skew parameter to lean the envelope left or right, and a parameter to set the total envelope duration.

Parameters

input

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


This parameter gives you access to the threshold level of the input comparator used to detect the rising edge of the incoming trigger signal. There is also a button for manually firing triggers.

duration

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

bias (0s to 1s)

time in seconds


This parameter determines the duration of the envelope from start to finish.

skew

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

bias (-1 to 1)

linear


Pulls the apex of the envelope forward (positive skew) or backwards (negative skew). A good value for a punchy attack with pleasant amount of release is -0.5.

level

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

bias (-1 to 1)

linear


Sets the height of the envelope's apex.
