Convert
Right-clicking on a value in the Parameters dialog brings up a context menu which has a sub-menu called "Convert". The "Convert" menu allows you to specify that the parameter should be controlled automatically in various ways. Depending on the type of the parameter the Convert menu will contain different options.
Contents
linear
Converting a parameter to be 'linear' adds two real-valued sub-parameters "Rate" and "Offset" for controlling the parameter's value.
The parameter's value will change linearly over time, start with the value specified by "Offset" at time zero, and increasing by the value specified by "Rate" every second.
reference
Converting a parameter to "reference" adds a single real-valued sub-parameter called "Link".
scale
Converting a parameter to "scale" adds two real-valued sub-parameters called "Link" and "Scalar".
sine
Converting a parameter to "sine" adds two sub-parameters: a angle value called "Angle" and a real-valued value called "Amplitude".
subtract
Converting a parameter to "subtract" adds three real-valued sub-parameters called "LHS", "RHS", and "Scalar".
