Press and Release

5-92 AutoTouch+
functions differs from faders and encoders. The differences are operational
mostly in nature and will be described in this chapter.
Pressing a switch performs two basic functions:
• Audio Function: The switch state is toggled to its alternate position.
• Automation Functions:
- Switch Press
- Switch Release
Under normal circumstances, a Switch Press produces a Touch event.
However, unlike faders and encoders, switches do not produce a Un-touch
event when they are released. The Switch Press audio toggle (switch state
toggle) event may be suppressed by holding down the AUTO MODE modi-
fier key when the switch is actuated.
AutoTouch+ recognizes Switch Press and Switch Release as separate and
independent events. The Touch event produced by a Switch Press serves a
separate from the Switch Press itself. This system allows the user to de-
termine what will take place when a key is pressed and also when it is re-
leased.
This independence allows switches to take on different behaviors depend-
ing on which functions Switch Press and Switch Release are allowed to
perform. The result is the ability for switches to operate in different modes
depending on the needs of the user.
Switches may operated using the following modes:
• Press and Release: Momentary Press and Release; Pressing the key and
immediately releasing it.
• Press and Hold: Pressing and holding the key down beyond a predeter-
mined time threshold.
• Modified Press Function: Holding the AUTO MODE key will suppress
the audio toggle function, but produces the Touch event when a key is
pressed. This mode allows the switch to be punched-in without toggling
its state.
Each of these functions are described below. The Modified Press Function
may be used with either Press and Release or Press and Hold operations.
The next three chapters make the assumption that the switches actuated
are in the proper enabled Control Mode as operations are carried out.
Press and Release is defined as using switches in a momentary manner. To
perform a Press and Release operation, press a work surface key and im-
mediately release it. The key is not held down any longer than it takes to
toggle the switch state.
Press and Release operations perform the following functions:
• Switch Press:
- Toggles the switch state
- Produces a Touch event
• Switch Release:
- An Un-touch event is not produced.
