4.3 Control Trigger
The term trigger also called trig and often interchangeable with the term
gate is a common control element for connecting in and across modular
and other systems. There are differences between gates and triggers. A
trigger would activate an event, for example initiate a drum sound and is
typically a short pulse. While these examples are generic, there can be
differences in how they are applied across systems.

NOTES
Trigger
A trigger is typically a short voltage pulse that will activate an event. For example
a trigger may activate a note on. In drum machines this would normally be a drum
hit and therefore the short trigger duration seems logical. Typical trigger levels are
from 0V to +5V sometimes referred to as V-Trig - Voltage Trigger, and also +5V to
0V referred to as S-Trig - Shorting Trigger, switch to ground. Clocks are often a
series of time synchronised triggers.
Gate
Gate and Triggers are very similar functions, where a gate follows the principles
of a trigger very closely. The main difference is that typically a gate has a longer
duration than a trigger and the gate may even be held high or held low rather than
transmitted as a single pulse. This is more common in melodic synthesizers
where notes and chord envelopes are sustained.
