Z-PLANE FILTER DESCRIPTIONS

F116 Bel>Crs>Bel

Morph: Sweeps from flat to dissonance.

Freq. Tracking: Provides key tracking to fix dissonant partials.

Transform 2: Increases bell-like effect. Makes the sound brighter and louder.

Comments: Low velocities on Transform 2 reveals a hint of bells when Morphing. Higher Transform 2 values create a more bell-like and dissonant sound.

F117 Chrs>Flng1

Morph: Sweeps to a flange effect.

Freq. Tracking: Provides key tracking to enhance flange effect.

Transform 2: Makes brighter, increases volume.

Comments: Degree of flanging effect depends on velocity.

F118 Chrs>Flng2

Morph: Sweeps to a flange effect.

Freq. Tracking: Provides key tracking to enhance flange effect.

Transform 2: Makes brighter, adds volume.

Comments: Velocity controls degree of flange effect.

F119 Ev/OdNtch.4

Morph: Sweeps from even notches at 200, 400, 800Hz, etc with an overall low frequency cut-off to notches at 300, 600, 1200, 2400Hz, etc. effecting a warm to bright transition.

Freq. Tracking: Provides key tracking.

Transform 2: Not used.

F120 Odd/EvnNtch

Morph: Provides subtle modulation between odd octave intervals starting at 75Hz and even octave intervals starting at 50Hz.

Freq. Tracking: Controls brightness.

Transform 2: Deepens the effect and adds volume.

F121 NotchPkSwp4

Morph: Sweeps from nasal to bright; vowel shifts from ‘oh’ to ‘ee’.

Freq. Tracking: Controls brightness and tracks keyboard.

Transform 2: Not used.

F122 1.5/3KNBPR4

Morph: Morphs from thin and high to richer and deeper to a yet a different timbre resonance; adds energy.

Freq. Tracking: Frequency Tracking thickens the spectral plot.

Transform 2: Not used.

Z-PLANE FILTER DESCRIPTIONS

F123 Swingshift

Morph: Try setting Transform 2 to 255 for brighter morph. Modulates from low-frequency cut-off to series of peaks at 349Hz, 494Hz, 698Hz, 988Hz etc.

Freq. Tracking: Tracks filter with keyboard. Transform 2: Adds depth, volume.

F124 500up.4

Poles and zeros alternate, spaced at 500Hz intervals. Increasing Morph Offset boosts the peaks slightly, and greatly deepens the notches, producing an effect similar to band-pass filtering. This effect is further accentuated by increasing the Frequency Tracking value, as well as tuning the entire filter higher.

Morph: Increases depth of notches. Freq. Tracking: Tunes the filter.

Transform 2: Not used.

F125 C1Harmonic5oct.8R

Morph: Try setting Transform 2 to maximum. Controls resonance.

Freq. Tracking: Controls resonance.

Transform 2: Tunes the filter.

F126 Odd>Even

Morph: Changes from odds to even harmonics.

Freq. Tracking: Provides key tracking to maintain spectrum. Transform 2: Controls brightness and volume.

Comments: Odd harmonics are replaced by evens. Can give an impression a raising one octave.

F127 0>Shp1

Morph: Changes from flat to shape.

Freq. Tracking: Provides key tracking to maintain spectrum. Transform 2: Controls brightness and volume.

Comments: Imposes a vowel like shape on a pure sound. (Can be useful for morphing in and out using two samples.)

F128 0>Shp2

Morph: Changes from flat to shape.

Freq. Tracking: Provides key tracking to maintain spectrum.

Transform 2: Controls brightness and volume.

Comments: More vowel like changes than 0>Shape1.

Z-PLANE FILTER DESCRIPTIONS

F129 0>Shp3

Morph: Sweeps to shape.

Freq. Tracking: Provides key tracking to balance keyboard brightness.

Transform 2: Controls brightness and volume.

Comments: Morphing imposes a shape on the sound. Low velocity for mellow, high for bright.

F130 Shp>Shp1

Starts with peaks every half octave from 66Hz and morphs to peaks every octave beginning at 66Hz Effect is “ee” to “u” with Frequency Tracking fully offset. Transform 2 reveals a completely flat response with all axes offset.

F131 Lpeq Vel

Morph: Moves between different “softs” & “brights”.

Freq. Tracking: Provides key tracking to maintain spectrum. Transform 2: Controls brightness and volume.

Comments: Position of the Morph determines the nature of the softness and brightness.

F132 CleanSweep4

A number of lowpass, highpass and bandpass type effects can be produced using this filter. It works particularly well on solo brass waves to produce a variety of mute effects.

Morph: Effects range from lowpass with low ‘Q’ to highpass with high ‘Q’.

Freq. Tracking: Increase for thinner, brighter and more resonant sounds.

Transform 2: Not used.

F133 PowerSweeps

Alternating resonant peaks and notches, spaced at approximately half-octave intervals can be used to produce a number of flanging and vocal effects. The direction of Morph depends on the Freq.

Tracking setting.

Morph: Modulating this sweeps the peaks/notches up and/or down.

Freq. Tracking: Tunes the filter; determines polarity of Morph. Transform 2: Can also be used to tune the filter.

Z-PLANE FILTER DESCRIPTIONS

••• A “brickwall” filter is one with an extremely steep slope.

F134 TSweep.4

A grouping of inharmonically related peaks gives this filter something 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 Tracking 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.
