Assuming
you
have
succeded
in
making
the
'400mS'
delaytime,
which
is
a
medium
echo
time,
a
shorter
single
‘echo
repeat’
should
now
be
audible.
It
is
a
straightforward
echo
effect
without
any
modulations
or
feedback.
Now,
to
give
the
sound
a
bigger
impression
we
will
make
the
echo
repeat
a
number
of
times
instead
of
just
once.
The
parameter
taking
care
of
this
is
the
FEEDBACK
LEVEL.
With
this
control
the
delay
echo
output
is
fed
back
to
the
input
of
the
delay
to
make
the
echo
‘recirculate’
or
‘repeat’
a
number
of
times.
Since
we
want
more
repeats
we
now
go
to
the
‘FEEDBACK
SECTION’
(-
strange
isn't
it
?)
and
find
the
value
'
0’
which
means
‘no
feedback’.

Let's
