section::Unary messages
Some synthesis processes can be initiated with a unary message (a message with no arguments).
////////////////////////////////////////////////////////////////////////////////////////////////////
For example, compare
code::
{ SinOsc.ar(500, 0, 0.5) }.scope;
::
to
code::
{ SinOsc.ar(500, 0, 0.5).distort }.scope;
::
The .distort message modulates the SinOsc to create more partials.
////////////////////////////////////////////////////////////////////////////////////////////////////
Q: Where does the .distort message come from?
A: It's defined in the AbstractFunction class. The UGen class is a subclass of the AbstractFunction class. The idea is that all classes inherit methods defined in their superclasses; all ugens thus inherit from AbstractFunction).
Compare
code::
{ SinOsc.ar(500, 0, 0.5) }.scope;
::
to
code::
// .cubed is a unary operation
{ SinOsc.ar(500, 0, 0.5).cubed }.scope;
::
