Z-PLANE FILTER DESCRIPTIONS
196
F100 MoogVocSwp
Similar to "MoogVocodr4", but brighter. Can create variety of interesting
responses by altering offsets of each axis, such as sweeping Morph with
Frequency Tracking at maximum.
Morph: Sweeps frequency.
Freq. Tracking: Increases resonance.
Transform 2: Changes the effect of the Morph parameter.
F101 StrngThing4
A series of widely spaced notches produces this filter, which can sound
somewhat like a phase shifter when Morphed - especially if the value for
Frequency Tracking is set fairly high. With Morph Offset and Frequency
Tracking set high, the curve is essentially flat, with a gentle bump ap-
proaching 20kHz, so this filter might be a good choice for adding a subtle
sparkle to some sounds.
Morph: Controls cutoff frequency and depth of notches.
Freq. Tracking: Tunes the filter.
Transform 2: Not used.
F102 StrSweep.4
Set Frequency Tracking between the ranges of 200 and 255, and gently
modulate the Morph Offset parameter in its upper ranges for an effect that
will accentuate bowing sounds in string programs.
Morph: Positive modulation increases filter center frequencies and
resonance.
Freq. Tracking: Positive modulation decreases resonance, increases
brightness slightly.
Transform 2: Not used.
F103 BassXpress
This filter provides increased bass, and a sharp notch.
Morph: Controls the depth of the notch.
Freq. Tracking: Tunes the notch.
Transform 2: Controls the lowpass filter cutoff frequency.
F104 Qbase.4
Morph: Sweeps from a bright nasal response to accentuated low-
frequency boost.
Freq. Tracking: Tracks filter with keyboard.
Transform 2: Not used.
