F106 Tube Sust.4
Use this filter with broad-band waves to produce sounds character-
istic of distorted guitars. The fullest sounds are achieved with
Morph Offset set to 255, and Frequency Tracking set to 000
Morph: Increasing this increases bass and midrange.
Freq. Tracking: Controls the lower-midrange.
Transform 2: Not used.
F107 GtrSkwk
Morph: Plays the squeak.
Freq. Tracking: Provides key tracking to balance keyboard bright-
ness.
Transform 2: Makes brighter, adds more volume and squeak.
Comments: Higher Transform 2 allows morphing to "string
squeak". Best used with Aux. Env or Function Generator to control
this. Routing Velocity to Transform 2 will reduce squeak on low
velocities.
F108 GuitXpress
Increasing the Morph Offset value places a notch in the frequency
spectrum, the tuning of which can be controlled via the Fre-
quency Tracking and Transform 2 parameters. In addition, in-
creasing the value for Frequency Tracking and/or Transform 2
raises the cutoff point of the lowpass filter. This filter can be used
to add a measure of expressiveness, particularly to acoustic instru-
ment simulations. Try using velocity to control Transform 2 and
key position to Frequency Tracking. For an additional measure of
control, assign Control A (the mod wheel) to control Morph in
the Note-on Control section.
Morph: Increases the depth of the filter notch.
Freq. Tracking: Tunes the notch and controls filter cutoff point.
Transform 2: Tunes the notch and controls filter cutoff point.
F109 FG MajTrans4
This filter features a series of peaks tuned to the intervals found in
a major triad. Modulating the Morph Offset from 000 to 255
moves the 'chord' from first to second inversion; the Frequency
Tracking parameter can be used to tune the chord over a range of
several octaves. The effect is perhaps easiest to hear applied to one
of the noise waves. It also works well with the RecrdScrch waves.
Morph: Moves the 'chord' of resonant peaks from first to second
inversion.
Freq. Tracking: Tunes the chord.
Transform 2: Not used.
