Using the gate function
The gate function in the A-178 gives you the facility to
have remote switching of events in real time, simply
by moving your hand towards the antenna.
The function can be used as a noise gate, using the
gate signal to switch a VCA on and off, either directly
or via an ADSR or slew limiter. Whenever the signal is
underneath a certain voltage, the VCA simply shuts
down.

In the patch in fig. 3, just a quick movement of one

fig. 3: User example for the gate function
An alternative to the patch in fig. 3 would be to use the
ADSR to control a filter as well.
Other possible uses: Start / Stop on a sequencer,
"one-shots" (ADSR-triggered noises, like thunder),
switching filter characteristics, etc. (see also the user
examples in the A-177 Foot Controller manual).
