Z-PLANE FILTER DESCRIPTIONS
212
F185 EvnHrm+rez
This filter cube is nearly identical to the 'OddHrm+rez' filter, but it's based
on the even harmonic series. The overall effect is quite similar, though
somewhat less 'hollow' sound at certain settings.
Morph: I n creasing this parameter pushes the filter towards a flat curve
and reduced 'Q'.
Freq. Tracking: Tunes the filter.
Transform 2: Tunes the filter. Higher values add a high-frequency
bump.
F186 MellowPeaks
This filter provides two or three mildly resonant poles which can be swept
through the frequency spectrum in a number of ways, depending on the
settings for the various parameters. With lower settings for Frequency
Tracking , the filter takes on a distinctly vocal quality on most source
material.
Morph: Positive values generally move the poles upward in frequency.
Freq. Tracking: Positive values generally move the poles upward in
frequency.
Transform 2: Positive values generally move the poles upward in
frequency.
F187 AHmBnd.4
The Morph Offset can be swept to sweep a cluster of resonant peaks,
producing a pitch-bend effect. The effect is generally most pronounced
with Frequency Tracking set to a fairly low value.
Morph: Sweeping produces 'pitch-bend' effect.
Freq. Tracking: Tunes the filter.
Transform 2: Not used.
F188 Vintage
Features an accentuated low end, and a series of notches which can be
swept via morphing. The most dramatic resonant sweeps are produced with
Frequency Tracking set to minimum and Transform 2 set to maximum,
producing the classic analog filter sweep sound.
Morph: Use to sweep the filter.
Freq. Tracking: Tunes the filter.
Transform 2: Controls filter resonance.
F189 MildQPole
Morph: Sweeps between a shallow roll-off low-pass to almost flat
response.
Freq. Tracking: Tracks keyboard.
Transform 2: At maximum, inverts morph effect.
