This
parameter
determines
the cutoff frequency, above or
below which
the TVF is applied to filter
out
the
specified frequencies
of the waveform.
Range:

The greater the value,
the higher the cutoff frequency.
If the filter has been
set to
LPF, lower
cutoff frquency values will decrease the higher
partials of
the spectrum, causing
the sound
to
become darker, and lower
in
volume.

If the
filter has been set to HPF, higher
cutoff frequency values will decrease
the
lower partials
of
the
spectrum, causing the sound to become
harder
or brighter.
Depending on the waveform,
high cutoff frequency values may
result
in no sound
if
the selected waveform does not contain
any partials
in the
frequency
range that is allowed
to pass.

Cutoff and
Envelope
The
normal
cutoff frequency, set in the cutoff
parameter,
is that frequency
where
the
level of the
envelope is 0. Therefore, the cutoff frequency increases or decreases
according to
changes
in the envelope level.
