Reference Functions

A function box refers to an underlying function that allows to execute a given operation.

OM Functions / Lisp Functions

There are two main types of function boxes : OM functions and Lisp functions .


	OM functions are specifically declared and assigned particular graphical properties : an icon, default inputs, etc. In other words, they have been designed for OM.
	Lisp functions are defined in the Lisp standard programming language. Their differ from OM functions by a "LISP" icon.

Both function types can be added and used in a patch following the same modalities.

Most of the time, it is necessary to thype the name of Lisp functions to add them in a patch editor, for they are not provided in the OM menus.

However, a set of useful Lisp functions is accessible

through the Function / OM Kernel / Lisp menu
in the OM Kernel / Lisp package of the Library.

Function Boxes Names

Changing the Name of a Function Box


	When added in a patch editor, a box shows the name of the function it stands for. Out of convenience, this name can be edited : double click on the text field and type a name.

Note that some boxes – for instance, basic functions like om+ – do not have editable names, due to their obvious meaning.

Name Changes and Function

Changing the name of a box doesn't affect its underlying function. Renaming a reverse box into a rotate box doesn't turn the box into a rotate function !

The function hasn't changed, although its name has been modified, as shown by its online documentation.
