2EQ + Lowpass Morph
Peak/Shelf Morph
This unusual filter has two EQ sections and a
lowpass filter whose Fc is also controlled by the
Morph parameter. The Lowpass filter is
completely open at a setting of 255. As the Morph
value is increased, the filter interpolates from the
low to high settings and the lowpass filter allows
more high frequencies to pass. The Q of the
lowpass filter has an initial setting and can also be
modulated realtime using the Filter Resonance
parameter. The gain parameter for each EQ
section stays constant during the morph.
This 2-frame morphing filter offers independent
control over frequency, shelving and peak for
each of the two filter “frames”. The Peak
parameter can also be modulated in realtime by
controlling the Filter Resonance parameter.
When the Shelf parameter is negative, the filter
will have a low shelving response. When the
Shelf parameter is positive, the filter will assume
a high shelving response. With Shelf at zero, the
filter assumes a peak filter response.
Note that the three controls of the two morphing
frames are grouped in this filter and all three
controls are morphed.
