Chorus/Flanger/ADT
Effects
And
now
to
something
completely
different.
The
TC
2290
can
also
be
used
to
produce
some
very
nice
delaytime
modulation
effects
such
as
Chorus,
Flanging
and
ADT
(automatic
double
track).
Quite
short
delaytimes
are
used
for
these
effects,
so
that
the
‘delay’
is
not
experienced
as
an
echo
but
rather
as
an
extra,
syncronized
voicing.
But
delaytime
modulation
can
be
applied
to
longer
delaytimes
to
produce
what
we
would
call
‘delayed’
chorus
effects.
Some
typical
delay
times
and
feedback
levels
are
tabulated
here.

We
will
use
our
preset
‘1’
again
as
the
base
for
making
a
chorus
setting.
Recall
preset
1
(which
you
haven't
destroyed
yet
7?
).
Press
<PRESET><1><ENTER>.
Now
we
are
back
at
the
delay
time
of
400mS,
with
no
modulations
-
(no
<MOD>
keys
should
be
on).
To
get
a
chorus
effect
we
want
to
decrease
the
delaytime
to
say
25mS.
Press
:
<DELAY
UP>
<2>
<5>
<ENTER>.
This
changes
the
sound
suddenly,
and
gives
it
a
somewhat
somewhat
more
‘bathroom’
sound
or
a
rather
static
‘flanger-like'
sound.
So
remove
the
feedback,
press
<FEEDBACK
UP>
<0>
<ENTER>
to
set
zero
feedback.
Now
press
the
<MOD>
key
in
the
DELAY
section
to
enable
delaytime
modulation,
which
gives
a
chorus
effect.

The
chorus
effect
is
simply
a
‘mix’
of
the
direct
signal
and
a
modulated
short
delaytime.
The
sound
is
characterized
by
a
‘moving
space’
or
‘multivoice’
character,
as
if
more
instruments
were
being
played
simultaneously
-
hence
the
name
‘chorus’.
When
the
<MOD>
key
of
the
DELAY
section
is
on,
the
delaytime
is
not
just
that
shown
in
the
delaytime
display.
It
changes
up
and
lower.
When
delay
and
direct
signals
are
mixed,
the
changing
delaytime
creates
the
movements
of
the
chorus
sound.
A
slight
pitchshift
also
occurs,
just
as
if
you
were
changing
the
playback
speed
of
a
taperecorder
up
and
down.
