Chapter 21: Events
This chapter introduces the Events tab, and explains how to use
the Event list.
Introduction
An event consists of one or more triggers, which are configured
to cause one or more actions to occur.
Events can be very simple, such as the press of a Function switch
enabling a Mute Group, or the press of a connected footswitch
triggering a Recall Next Snapshot. These are examples of a single
trigger (a press of a Function switch or the press of a footswitch)
causing a single action (enabling a Mute Group or Recall Next
Snapshot).
Events can also be quite complex and involve multiple triggers
and actions. For example, a single event can be defined so that
moving a specific fader above and/or below a certain level sends
a General Purpose output, recalls a specific snapshot and mutes
one or more channels. Multiple triggers can be considered condi-
tionally using the available logic operators AND, OR, and XOR.
Each event can have between 0 and 8 triggers, and each event can
have between 0 and 8 actions. Up to 999 events can be created.
The Event list is easy to configure, and many pre-configured
events are provided for Tap Tempo, next/previous snapshot, and
other functions.
Terminology
Event A user-defined combination of one or more triggers and
one or more actions. Each event serves as a type of software
“macro” in which you establish a cause-and-effect relationship
between one or more triggers and their results (actions).
Trigger A conditional check used to fire an event, such as the
press of a Function switch.
Action A command, mode or other response resulting from an
event being triggered.
GPI General Purpose Interface, also commonly known as a logic
interface. S3L provides 2 GPI inputs and 2 GPI outputs.
Open GPI input or GPI output is floating, or at its reference volt-
age.
Closed GPI input or GPI output is closed.
Footswitch Footswitch ports are functionally identical to GPI in-
puts and share all of the same properties and behaviors.
Important Information about Snapshots
and Events
Because events can trigger snapshot recalls, and because snap-
shot recalls can trigger other events, it is possible to create logic
“feedback loops.” For more information, see “Avoid Feedback
Loops” on page 223.
For more information on the default events and other exam-
ples, see “Default Settings, Templates and Examples” on
page 224.
