Modulation Effects
Although “modulation” usually implies some sort of cyclical variation, the VL1
Modulation stage allows selection of Flanger, Pitch Change, and Distortion effects (only
Flanger fits the traditional definition of a modulation effect). Since most of these effects
produce a marked change in the sound, you’ll probably only want to use them on certain
voices, and maybe not all the time.
NOTES Refer to page 46 of the Feature Reference manual for full details on
the Modulation effects and parameters.
Feedback Delay Effects
All three effects available in the Feedback Delay stage are basically designed to
produce distinct repeat delays or echoes. You have extensive control over the number of
repeats produced and the way they decay.
This type of effect is created by slightly delaying the sound and
periodically varying the delay time. The delayed signal is then added to
the direct signal causing a variable comb-filter effect which results in
the familiar “swishing” flanger sound.
A dual pitch change effect which can be used in the Mono mode, in
which both pitch-shifted notes appear on both channels, or the Stereo
mode in which one pitch-shifted note appears on the left channel and
the other on the right. The pitch of the two pitch-shifted notes can be
set over a two-octave range — from one octave below to one octave
above the input note.
An extremely versatile distortion effect which offers transistor, vintage
tube, fuzz and other distortion types, a variety of speaker types, and a
comprehensive range of other parameters that can be used to refine
the distortion sound.
Since the goal in producing a delay effect is often to match the delay time to a
musical time value, the VL1 includes a “time calculation” function that makes it easy to
convert standard note values to their corresponding delay times in milliseconds.
The Mono delay effect produces a single delay sound which appears in
the center of the stereo sound field.
This variation provides independently programmable delays for the left
and right stereo channels.
Independent delays are provided for the left and right channels, plus a
center delay.
