Another way to look at the Z-Plane filter is simply as a “black box”.
You don't really need to think about all the possible filter permuta-
tions in order to use it. You just need to know what the controls do
and listen to the sound. Each Z-Plane filter is described in the Refer-
ence Section of this manual.

Filter Type
The Morph and Transform 2 parameters vary in function from filter to
filter.
About half of the Z-Plane filters are not Cubes and
therefore DO NOT use Transform 2. The Frequency Tracking
parameter usually controls the frequency of the filters, moving peaks,
shelves or notches up and down in frequency. Refer to the Reference
Section of this manual for specific information on each filter.
Many of the filter types in Morpheus are models of traditional acoustic
instruments such as electric piano or guitar. When an electric piano
sample is played through an electric piano filter, the harmonics of the
sample can now be controlled using the filter parameters.
Of course, you can put any instrument through the filter and the filter
will shape the basic character of the instrument. This “building-block”
approach to synthesis is only a part of what makes Morpheus such a
unique and powerful synthesizer.

The Z-Plane filter can change its function in time.
Imagine a Lowpass filter transforming into a Bandpass filter. The
Morph parameter (Morph Offset) typically handles this type of
function.

Frequency Tracking param-
eter DOES NOT control the
filter frequency. See the filter
descriptions in the Reference
Section for details.
