To display information about an inlet, keep Cmd pressed while hovering the mouse over the inlet. A tooltip appears and displays
a parameter name,
a short documentation about this parameter.
Default Values
All box inputs have default values that are used by the box if no values have been specified by the user, or if the box is not connected to anything.
To visualize the default value of an inlet, hover the mouse over it. If it is connected to any kind of component – such as a value or a box – this default value will be ignored.
The default pitch of a note is 6000 midicents, that is, a C4.
The value remains hidden unless you hover the mouse over the inlet.
SHIFT click on the inlet to display the input value in a connected data box that will remain visible.
Saving Values
Always validate
after entering a value in an inlet :
click in the window
press Enter.
This is very important since default values can remain hidden.
Input Menu
When the number of possible values is very limited for an argument, some functions display a pop up menu where the user can pick the desired value.
To chose a menu item, click on the input, and click again in the pop up menu.
The list-filter function has three arguments : the numberp predicate, a list and an action (pass or reject). Here, it passes numbers only (pass + numberp) and returns (2).
