Input Boxes

The inputs of an abstraction are represented by inner boxes. Once edited, the patch can be evaluated internally and autonomously.

Editing Inputs

To edit the inputs of an abstraction, double click on an input box to open its editor.

The editor displays :

  • the input name,
  • an editable "Documentation" frame,
  • an editable "Default Value" frame.

To edit information :

  1. enter values and / or a documentation,

  2. choose Apply

  3. close the input box once to validate the default values and documentation.

To display the information :

  1. Ctrl / right click on the patch and choose Update Doc

  2. press Cmd while hovering the mouse over the patch.

Using Default Value

Default values allow to evaluate an internal patch from the inside.

Using an Instance as a Default Value

The lower left frame of the input editor can take an instance as default input value.

To add an instance or a global variable there, drag an instance box from a patch editor – or from the Globals package to this frame.

An instance can be created out of a factory box and dropped, as well as a global variable, from a patch editor to an input editor.

Reminder

SHIFT + Cmd click on an outlet to create an instance in a patch editor.

About Instances and Global Variables :

Internal Evaluation

Default values are designed to test if a patch works with an internal evaluation.

To evaluate a patch internally, Cmd click on the internal output box.

Default values are ineffective as soon as a patch is evaluated from the outside.

Note

Default values are also ineffective if values are sent to the patch from other boxes.
