116 UltraProteus Operation Manual
Each axis of the three-dimensional cube changes the filter in a different way. In
the example above, key number is being applied to the Frequency Tracking
parameter in order to make the filter frequency track or follow the notes played
on the keyboard.
In the 3-D filter model, there is another note-on (defined at the time the note is
pressed) parameter, Transform 2. Unlike the frequency tracking parameter, the
effect of Transform 2 varies from filter to filter. In the example above, Trans-
form 2 is being used to vary the size of the peaks and notches in the filter. The
frequency plots in the upper plane of the cube have sharper peaks. In the
example above, key velocity is being used to control Transform 2 and the
sharpness of the filter peaks.
Filter Transform 2 sets the Initial Point along the Transform 2 axis. Subsequent
modulation (from note-on modulation) adds to this initial setting for the
primary and secondary filters.

Filter Reverse
This function allows you to reverse the direction of all of the filter controls. Key
Tracking, Transform 2 and the Morph parameters will all operate in reverse.
The Offset points are reversed, as well as the direction of filter modulation.

Auxiliary Envelope
This is a supplementary, utility envelope that can be routed to any realtime
control destination including the Morph filter. The auxiliary envelope param-
eters are: Envelope Amount, Delay, Attack Time, Hold Time, Decay Time,
Sustain Level, and Release Time. The delay time is variable from 0 to 13 seconds
(000-127). The envelope amount is variable from -128 to +127. Negative values
will produce inverted envelopes.
