In these
two
pages, these
parameters determine
the
depth of
LFOs
1
and
2
that
are applied to the
TVF
cutoff
frequency.
The greater the value, the greater the variation
in
the cutoff frequency. Setting the
parameter
to
either
positive
or negative values reverses the direction of the cutoff
frequency change.

Filter

Settings:
OFF/LPF/HPF
This determines
the
type of
TVF
for
each Tone.
The LPF
(low pass
filter)
setting
allows the
low elements of
the
frequency
to
pass unfillered.
The
HPF
(high pass
filter)
setting
allows
the
high elements of the
frequency
to
pass
unfiltered.
The
filter
does not function
when
set to
OFF.

This determines
how
the
TVF
cutoff
frequency of each
Tone
changes
in
response
to
the
key range played.
With
the
C4
key
as a
standard of
reference,
when
the
value
is
positive
(+).
the
higher
the
key
played, the higher the cutoff
frequency.
When
the value
is
negative
(
-
),
the
lower
the
key played,
the
higher the
cutoff frequency.
The
farther
the
value
is
set
from
0.
the
greater
the
change
(increase
or decrease) of the cutoff
frequency
becomes
for
both
positive and
negative
values.
