How to set up a button press delay for control signals

Product:Composer Management Software

Type: Control

In some situations, you may need to avoid unintentional button presses on a control screen or external controller. This could be to trigger a preset, power down a system, or a myriad of other cases.

This could translate into the user needing to hold a button for a given amount of time before a control will activate. We can achieve this with a ramp processor and threshold detector.

Drag in these modules and wire them as shown below.

This functionality can be used with either a momentary button or latched button. The control meter at the end of this example simply shows the 100% signal flowing through the TRUE output of the threshold detector. This could be a remote control number output, preset trigger, network string output, etc.

When the ON button is pressed and held, we can see 100% control signal inputting into the ramp processor which slowly raises its output level from 0% to 100% over the span of time set by the UP rate. We see the ramp processor output then inputting into the threshold detector’s input.

Once the ramp processors output has reached 98% or higher (as set by the Threshold A slider), the threshold detector allows the signal to pass through its TRUE pin, causing the control meter to reflect 100% input.

The threshold detector could also have its FALSE pin connected to something that would trigger something else when the button is in the off state.

Additional note: logic functionality doesn’t work live in Composer unless it is online with the system.
