Chapter 5 – Overview of Effects

Quad Chorus

Quad Chorus modulates four delayed signals, each with independent rate and depth
controls. Each of the four signals has a separate Predelay variable, allowing you to
change the "rhythm" of the phasing.

Quad Pitch Shifter

The Pitch Shifter effect transposes the pitch of the incoming signal by a fixed amount.
It is useful for creating parallel harmonies, detuning, chorusing, and special effects.
The Semi parameter shifts the pitch in increments of one half step, with a range of up
or down one octave. The Fine parameter detunes the signal in very fine increments,
with a range of up or down one half step. Also available are Delay and Feedback
parameters. The Delay parameter delays the shifted signal up to 250 ms, or can be
used with the Feedback parameter to produce decaying arpeggio effects. There are
also Low Cut and High Cut filters in the feedback loop which can be used to alter the
timbre of the sound as it repeats. The Quad Pitch Shift configuration provides two
discrete pitch shifters, each with their own Pan and Level control.
Both the Quad Chorus and Quad Pitch Shifter have stereo Input and stereo Output
routing. The Left Input feeds Voice 1 and the Right Input feeds Voice 4. Voices 2 and
3 are fed by a mix of the Left and Right Input. These Voices are similarly panned in
the Outputs: Voices 1,2,3 and 4 are panned from hard Left to Hard Right.

Chorus:Chorus

This is a dual mono configuration with two independent mono Chorus/Flangers.
Even though the configuration is called Chorus:Chorus, you can use it as a dual
Flanger, or even a Chorus and a Flange. Both the controls and the I/O are separate,
so stereo imaging will be maintained. By setting the left and right sides to slightly
different settings, you can achieve a wide stereo image.

Chorus

This is a mono, less processor-intensive version of the Stereo Chorus effect, used in
Multi Chain Configurations (Chorus Room, Room Flange, Flange Delay
Room) and Dual Configurations (Room+Chorus).

Lezlie

With the Lezlie effect (found in the Lezlie->Room Configuration), the pitch change
block becomes a rotating speaker simulator. This effect was extremely popular
during the 1960's and was achieved by mechanically rotating the speakers to produce
complex timbral changes. The Lezlie speaker system is most often used with rock
organs, but is occasionally used for guitar amplification as well. Parameters include:
Motor on/off, Speed, which can be slow or fast; and High Rotor Level, which lets
you attenuate the volume of the high frequencies. When switching the Lezlie effect
on and off, or when changing the speed between fast and slow, the effect will ramp
rather than change abruptly, just as a true Lezlie speaker system would do. By
raising the High Rotor Level, you can really make this effect scream. Tip: Try
modulating the Motor or Speed with MIDI Aftertouch.
