2Eq + Lowpass Morph; Peak/Shelf Morph - E-Mu ProteusX Operation Manual

2EQ + Lowpass 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.

Peak/Shelf 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.
