F168 CntrySweep4
Multiple peaks are swept in a variety of directions, imparting a phase-
shifter-like, almost vocal quality when this filter is morphed.
Morph: Set this higher to move widely spaced peaks closer together.
Freq. Tracking: Set this higher to move low-frequency peaks towards
the higher ranges.
Transform 2: Not used.
F169 Diffuser4
Morphing this filter upward sweeps a resonant peak up in frequency and
increases low frequency content. The Frequency Tracking parameter can be
used to tune the peak.
Morph: Use to tune the resonant peak and control low-frequency
content.
Freq. Tracking: Use to 'tune' the resonant peak and control low-fre-
quency content.
Transform 2: Not used.
F170 MdlySweep4
Morphing this filter upward sweeps several resonant peaks up in frequency.
The Frequency Tracking parameter can be used to tune the peaks.
Morph & Freq. Tracking: Tune the resonant peaks.
Transform 2: Not used.
F171 StrongShimr
This filter produces several deep notches in the frequency spectrum, which
can be tuned or swept according to the settings and modulators for the
Morph Offset, Frequency Tracking, and Transform 2 parameters.
Morph: Raising this value lowers the frequency of the notches, produc-
ing thinner sounds.
Freq. Tracking: Raising this value lowers the frequency of the notches,
producing thinner sounds.
Transform 2: Raising this value raises the frequency of the notches,
producing fatter sounds.
F172 Acc.Vel-1
Morph: Fixes soft "Start-point".
Freq. Tracking: Provides key tracking to balance keyboard brightness.
Transform 2: Controls brightness and volume.
Comments: Velocity cube. Use Morph to establish soft start point.
F173 Acc.Vel-2
Variation of "Acc.Vel-1", except somewhat brighter on bottom and mel-
lower on top.
