Section 4 - Algorithms
SMALL ROOM REV, LARGE ROOM REV, HALL REVERB
The algorithm
name
is the first
parameter
for all of the algorithms:
00
-
Small
Room
Rev provides ambience.
00
- Large
Room
Rev, larger
than
Small Room Rev, also
provides
ambience.
00
-
Hall
Reverb is a large acoustic space,
and
provides
high
density reverb.
Small Room Rev, Large Room Rev, and Hall Reverb Signal Routing
58
Main
Outputs
R
These three reverb algorithms
share
essentially
the
same
signal
routing
topology. The signal
enters a
low
pass filter,
and
goes directly through the diffusers
which
smear
the signal. The
signal is
then
routed
to a larger decay diffuser,
known
as Definition,
and
is diffused
over
a
period
of time (creating a decay). There are
taps
from
both
the
left
and
right Definition that are
routed
to
the
output
to create a synthesized stereo output. A signal from
the
Definition goes
through
a
low
pass filter followed
by
a
low
frequency decay parameter, which controls the rate of decay of the
low
frequencies. There is also a
parameter
at
this stage
that
controls
the
decay time of
both
the
left
and
right signals. The left
and
right signals are
routed
back
into the Definition. There are
two
echo times
between
the diffuser
and
the definition
that
can
be
routed
directly to the
output,
or
sent
back
through
the definition. There is also
an
external
dry
signal (not shown) that goes
directly from the
input
to the
output
and
is
controlled
with
the
mix
parameter
(01).
The
parameters
available for
the
small room, large
room
and
hall reverb algorithms are:
01-Mix
02-Volume
These
parameters
are identical for all of the algorithms
and
are explained
in
detail
under
the
Mix
and
Volume Parameters description,
found
in
the beginning of this section. The reverbs
sound
best
with
a Mix of
wet
and
dry.
