# IO Event Triggers

## Overview

In the following section, all Cosmo event triggers and their characteristics will be presented. 

Generally, these event triggers are customized and can be configured via a profile as desired.

The purpose is to provide the option to connect a specific IO activity to a particular event or button.

## Trigger 'limitations'

### Custom\_IO

This trigger can be compared with its equivalent in FX - [Custom\_FX](/helmut4-releases/v4.9.1/helmut4-components/helmutfx/streams/fx-event-triggers/custom_fx.md).

It can be used within Premiere Pro / After Effects from the[ Helmut Panel](/helmut4-releases/v4.9.1/helmut4-components/helmut4-panel/panel-dashboard.md). Any assigned stream will be shown when clicking the 'Action' button.

The purpose of this trigger is to initiate a stream based on sequence, composition, or project criteria.
