To conclude, selecting the REVERB folder allows you to display the page relating to programming
of the Reverb effect.
Reverb originates as the sum of the various acoustic reflections produced by a sound in a natural
environment. If you clap your hands inside a large reflective environment, such as a church, you
will hear a strong resonance which gradually dies away; this is due to the church’s internal
reverberation.
The acoustic response of a specific type of reverb depends on a large number of factors. These
include the size and design of the room, the material with which it is lined, and many other aspects.
The Reverb algorithm is able to reproduce all these factors digitally.
The video page contains the following parameters:
•
STATUS
([CHORUS])
: inserts the Reverb effect in the effects chain (INSERTED) or bypasses it
(BYPASSED).
•
TIME: sets the reverb time, meaning the time for which the sound is propagated and reflected
inside a room, in a range of values from 0.2 sec. to 24 sec.
•
TYPE: sets the type of environment in which the reverb occurs. The possible options are the
following:
-
HALL 1: reverb in a large hall with highly reflective walls, such as a church.
-
HALL 2: reverb inside a room smaller than the LARGE HALL and with less reflective
rooms, such as a concert hall.
- ROOM 1: reverb in a medium sized room with not very absorbent walls.
-
ROOM 2: reverb in a small room, with highly absorbent walls.
-
VOCAL: reverb picked up with a microphone.
-
PLATE: reverb generated by means of a metal plate, using the simulation method of
the ‘70s.
•
PRE-DELAY: regulates the cut-off frequency of a low-pass filter capable of eliminating all
frequencies above that set.
•
LEVEL
([LEVEL] with the LED of the [LEVEL/PARAMETER] button off)
: regulates the level of the signal
leaving the Reverb effect.
•
PARAMETER KNOB ASSIGNED TO: defines which of the parameters shown in the video
page can be regulated using the trimmer associated to the Reverb effect (the first from the left
in the EFFECTS) when the LED of the [LEVEL/PARAMETER] key is on.
