EFFECTS SECTION
Room programs simulate small rooms
with high frequency absorption caused by
drapes and furniture.
Plates simulate plate type reverbs with
their tight, dense early reflections and
sharp reverb build-up.
Chambers simulate medium sized rooms
with hard reflective surfaces.
Hall programs recreate the open, spa-
cious ambience of large concert halls.
Early Reflection programs consist of the
reflection cluster only without the reverb
decay. These effects are similar to a
multiple tap delay line and have a single
adjustable parameter - Ambience.
The special reverbs Rain & Shimmer are
variations of the early reflection programs
and consist of a dense group of short
echoes followed by longer echoes.
FXA:Hall 1
Decay Time: 165
Place the cursor underneath the reverb
name and use the data entry control to
change the type of reverb. Moving the
cursor to the lower line allows you to
change the decay time of the reverb.The
decay times of the reverb programs vary
from effect to effect (Rooms: 50-250,
Small Rooms: 10-128, Halls: 100-255,
Chambers: 50-200, Plate 1: 80-200,
Plate 2: 80-250.
The Early Reflection programs have an
Ambience parameter which is variable
between 0-100. The ambience parameter
is a diffusion control which simulates the
effect of an irregular wall surface as the
amount is increased.
REVERB EFFECTS
Room
A bright, medium sized room. The
apparent source position is fairly close to
the listener. Suitable for use with 100%
wet mix setting for adding ambience.
Warm Room
This reverb is similar to “Room” with
more high frequency absorption, slightly
larger size and a more distant source
position.
Small Room 1
This reverb is also similar to “Room” with
shorter initial reflections, shorter decay
times and higher reflection density due to
the reduced room size. The apparent
source position is closer to the listener.
Small Room 2
This reverb is a variation of “Small Room
1” with greater high frequency damping
and a more distant source position.
Hall 1
Hall 1 is a large, highly reverberant space
with auditorium-like acoustics. Like all
the Hall programs, “Hall 1” exhibits a
warm, distant ambience with slow reflec-
tion density buildup. With the decay
parameter set to maximum, “infinite”
reverberation effects can be obtained.
Adjustment of wet-dry mix can be used to
position the listener from the “front row”
(
≈
25%) to “back of the balcony” (
≈
100%).
Hall 2
This reverb is similar to “Hall 1”, but
harder and brighter, with more pro-
nounced slap echoes that come from
parallel reflecting surfaces in the room.
Hall 2 also exhibits a pronounced reverb
“bloom” or late-reflection buildup. A 50%
wet mix creates the optimum “close”
distance adjustment.
