Enable

The ‘Enable’ button activates processing on the relevant channel. If the chan-
nel is not enabled, signals pass through it unmodified.

Function

The ‘Function’ drop-down menu allows you to choose the function that
will be applied to the incoming signal. The options are:

Linear - a simple linear function. If no scale and offset are applied
(see below) this doesn’t modify the signal at all.

Logarithm - the output is 1.0 plus the logarithm (to base 2) of the input. The output is
zero for negative inputs.

Exponential - the output is the exponential (to base 2) of the input minus 1.0.

Absolute - the output is the absolute value of the input.

Scale and Offset

The ‘Scale’ and ‘Offset’ knobs apply scale (multiplication by a value) and offset
(addition/subtraction of a value) before and after the function chosen.

The input scale and offset knobs are to the left of the graph; the output scale
and offset knobs are to the right.

Graph

The display in the centre of the plug-in UI shows the chosen function as a
graph. The input is on the ‘x’ (horizontal) axis and the output on the ‘y’ (verti-
cal) axis.

A small moving indicator on the graph shows the current input and output values.

The output scale and offset knobs modify the graph to show their effect. The input scale
and offset knobs do not modify the appearance of the graph, but you can see their effect
on the movement of the indicator.
