KeyState : UGen : AbstractFunction : Object

Respond to the state of a key
Source: MacUGens.sc

Description

Respond to the state of a key.

NOTE: Note that this UGen does not prevent normal typing. It therefore may be helpful to select a GUI window rather than an SC document when using KeyState, as the latter will be altered by any keystrokes.
