Z-PLANE FILTER DESCRIPTIONS
220
F224 HarmShiftr3
Harmonically related filter bands can be moved around by adjusting Filt.
Freq. Track. Higher values for Transform 2 increase overall filter effect.
Morph: Higher values decrease bandwidth.
Freq. Tracking: Tunes the filters.
Transform 2: Increases depth of peaks and notches.
F225 Phaser
Morph: Spreads all the filters from a single frequency to multiple
frequencies.
Freq. Tracking: Controls polarity of the filters; below 127 yields
notches, above, peaks.
Transform 2: Controls filter bandwidth; higher values are wider bands.
F226 HrmncPhaser
The effect of Morph and Freq. Track used together is cumulative; the
highest-band effects are found with both set to 255.
Morph: Higher values tune the filters higher.
Freq. Tracking: Higher values tune the filters higher.
Transform 2: Notches if set below 127, peaks if above.
F227 HrmncPhsr2
Peaks and notches cross one another to produce a variety of phase shifter-
like sweeps.
Morph: Increasing values move peaks lower, notches higher.
Freq. Tracking: Higher values increase depth of peaks and notches (at
000, filter is flat).
Transform 2: Higher values increase filter bandwidth.
F228 Wide Bands
With Transform 2 set low, Morphing produces a series of widely spaced
notches over several octaves. Higher Transform 2 values result in widely
spaced peaks.
Morph: Increases depth of notches and peaks.
Freq. Tracking: Tunes the filter.
Transform 2: Controls polarity.
F229 New Boost
An attempt to make a more versatile version of the popular F71 B Boost.4
filter.
