Z-PLANE FILTER DESCRIPTIONS
190
F067 Ntches2Oct4
This filter is composed of a series of notches, tuned in octaves.
Morph & Freq. Tracking: Moves notches lower in frequency.
Transform 2: Not used.
Comments: Maximum shift is two octaves along either axis, for a
combined total of four octaves if both axes are modulated.
F068 Odd>+
Morph: Changes from odd to even harmonics.
Freq. Tracking: Provides key tracking to maintain spectrum.
Transform 2: Provides volume and brightness control.
Comments: Hints at odd harmonics which are then changed into a
different shape depending on the position of Transform 2.
(Transform 2 mostly respects natural changes in brightness, how-
ever.)
F069 VarSlope.4
A low-pass filter in which the rolloff above the cutoff point (400Hz) be-
comes steeper as the value for Morph Offset is increased.
Morph: Changes the slope of the rolloff.
Freq. Tracking: Moves the filter toward flat response.
Transform 2: Not used.
Comments: A good choice when more subtle filtering is desired.
EQUALIZATION FILTERS
Most of these filters are variations of traditional parametric EQ filters.
F070 BassEQ 1.4
Morph: Contains deep notch at 196Hz, morphing to a slight bump at
132Hz and a dip at 2600Hz.
Freq. Tracking: Frequency Tracking opens filter completely at maxi-
mum offset.
Transform 2: Not used.
F071 B BOOST.4
Morph: Boosts frequencies around 60Hz, sweeping to open response.
Freq. Tracking: Provides gentle rise at 320Hz and 5kHz.
Transform 2: Not used.
