Logic Gates
Most Logic Gates have no Control Dialog Boxes. They are used only to customize behavior of other control functions
in the system. Logic Gates are connected between the output and input control nodes of other components in the
layout. These components can represent internal or external control functions.
Examples
Internal
: Auto Mixer output nodes; Ducker input/output nodes; Remote Preset Button input nodes.
External
: S8 output nodes; V8 output nodes; Voltage Command Box input/output nodes.
Logic Gates alter the normal operation of component control outputs in the following ways:
NOT
: produces opposite/inverted operation (input ON turns output OFF; input OFF turns output ON).
AND
: all inputs ON causes output to go ON (any inputs OFF causes output to go OFF).
NAND
: all inputs ON causes output to go OFF (any inputs OFF causes output to go ON).
OR
: any inputs ON causes output to go ON (all inputs OFF causes output to go OFF).
NOR
: any inputs ON causes output to go OFF (all inputs OFF causes output to go ON).
XOR
: any inputs (except all) ON causes output to go ON (all inputs OFF/ON causes output to go OFF).
Flip Flop
: produces toggle/latching operation (input ON changes output state, ON/OFF).
Logic State
: provides manual latching operation only (includes no input node).
NOTES: NOT and Flip Flop gates have only a single input per output, whereas most other gates have multiple inputs,
up to 8. Flip Flop gates provide a control dialog box, for establishing their initial output state. Also, unlike most other
blocks, multiple control output nodes may be connected to a single control input node on a Flip Flop gate. Control
Dialog boxes for Logic State gates can be minimized to create user control surfaces (see Customizing Component
Objects).
Sample Application
Normally, a S8 control output connected to a Ducker control input provides a
momentary operation (ducking occurs only as long as the S8 control is being
pressed). However, connecting a Flip Flop Logic Gate between the S8 control
output and the Ducker control input produces a press-on/press-off operation
(ducking begins with the first press of the S8 control, and ceases only upon a
second press of the S8 control).
Logic Delay
Logic Delays are connected between the output and input
control nodes of other components in the layout. These
components can represent internal or external control
functions. Logic Delay outputs simply provide a delayed
version of the changes received at their inputs. On sets turn
on delay. OFF sets turn off delay. The range for either
selection is 0~60,000mS (1 minute). Bypass disable the delay
without changing settings. Right-clicking over certain settings
will provide a menu of additional options.
