Z-PLANE FILTER DESCRIPTIONS
F134 TSweep.4
A grouping of inharmonically related peaks gives this filter some-
thing of a metallic quality, although it can also produce voice-like
sounds. Increasing Morph Offset increases overall filter resonance
and raises the cutoff point of the lowpass filter. Frequency Track-
ing can be used to tune the filter.
Morph: Controls ‘Q’; controls lowpass cutoff.
Freq. Tracking: Tunes the filter.
Transform 2: Not used.
F135 SweepHiQ1.4
Morph: Sweeps from peaks at 150Hz, 430Hz, 870Hz , 1500Hz,
3000Hz and 7000Hz to peaks an octave higher.
Freq. Tracking: Introduces high Q peaks at 1.2kHz and 3.4kHz to
narrowly spaced peaks at 1500Hz to 15kHz.
Transform 2: Not used.
F136 V>FcQuad.4
Designed for velocity to control filter cut-off. Each frame has an
octave higher cut-off than the one before it.
Morph: Moves from a bump at 320Hz then a brickwall cut-off up
an octave.
Freq. Tracking: Tracks keyboard.
Transform 2: Not used.
F137 Nexus.4
Morph: Moves from a brickwall low pass to higher frequency,
relaxed slope response.
Freq. Tracking: Frequency Tracking at maximum inverts effect of
morph.
Transform 2: Not used.
Comments: Designed for Frequency Tracking to control brightness
with velocity.
F138 Krators.4
Morph: Provides resonant peaks at low-frequencies, morphing
from lower to higher frequency.
Freq. Tracking: Controls brightness.
Transform 2: Not used.
Comments: Designed to control brightness by assigning Velocity
to Frequency Tracking.
••• A “brickwall” filter is one
with an extremely steep
slope.
