Morpheus Operation Manual90
PRESET PROGRAMMING
Because creating the complex filtering is difficult and very time con-
suming, we have created hundreds of filters and installed them perma-
nently in ROM for your use. You simply select and use the filters in a
manner similar to choosing an instrument. Because there are so many
types of filters to choose from, the number of possible permutations is
staggering. For example, you could play a guitar sound through a
vocal tract filter and create a talking guitar sound. Or you could have
an acoustic guitar whose body shape changes as you play.
In the current example, two complex filters were created and the
Morph parameter was used to interpolate between them. This is the
simplest way to visualize a Morpheus filter
The next logical extension of this two filter model would be to add yet
another filter pair. The diagram below shows an example using four
filters. Now we have two parameters that can be controlled.
The diagram above, adds a Frequency Tracking parameter which varies
the frequency of the filter. If we had set the frequency tracking and
morph parameters as shown in the diagram above, the dot would
represent the resulting filter position: a mixture of all four, but closest
in nature to the left rear filter.
In the Morpheus filter there is only one parameter that can be continu-
ously varied in realtime and that is the Morph parameter. Other filter
parameters, such as Frequency Tracking, can only be changed at note-
on time.
