4.3 Curves

All available 12 Step curves:

Linear

A 1:1 linear “curve”. Values passing through will not be modified in any way.

Sine

Applies a sine curve to incoming values.

Cosine

Applies a cosine curve to incoming values.

Exponential

An exponential table. Lower values rise slowly —

 

higher values rise quickly.

Logarithmic

A logarithmic table. Lower values rise quickly, higher values rise slowly.

DeadZone

Similar to the Linear curve. This curve also has a “dead zone” in the center —

 

values near the center 

will not move at all until the dead zone has been exited. This is good for sources like Tilt, making it 
much easier to accurately return to center.
