14 Vocal Distortion
Program for distorting vocal sounds,
resembles the sound produced by a
distorted megaphone. The sound
depends largely on the selected
variation.
Try it and see! Can also be used for
processing organ sounds.
15 Rotary Speaker
A popular effect in combination with
organ sounds, as it simulates the
sound of a horn-loaded speaker
rotating in a wooden cabinet and
driven by an electric motor. The
resulting sound effect is somewhat
similar to a tremolo.
The Rotary Speaker effect is not
limited to organs and keyboards, but
also produces interesting sounds if
used with, for example, guitar
sounds.
16 Vocoder
Simulation of a "Voice Coder". The
left channel’s signal is controlled by
the right channel, i.e. you can control
a keyboard sound (left channel) by
singing or speaking into a
microphone (right channel).
This effect was frequently used in the
disco music of the 70’s, but is still
"in" today. Most often used to modify
voices in combination with
instrumental sounds.

APPLICATION
17 Pitch
Pitch shifters transpose the source
signal (tunable in cents and semi-
tones) and then add it to the original.
Particularly suitable for doubling
vocals and solo instruments.
18 Flanger
Similar to the chorus effect, but with
an addtional feedback parameter,
which is why flangers produce a
much more "floating" sound that
seems to wander through the room.
Suitable for all bright sounding
instruments such as guitar, bass,
electric piano or cymbals. Also used
to produce peculiar vocal sounds.
19 Chorus
Chorused sound produced by slight
pitch shifting and time delays.
Chorus is idealy suited to make
instruments sound "wider". In
particular, guitars and basses get
more punch from a chorus. Also
used to enhance thin-texture string or
pad sounds.
20 Tremolo & Delay
This program simulates the tremolo
effect typically found on guitar amps
and combines it with a delay. The
tremolo effect is produced by
modulating the volume of the source
signal. This algorithm also allows for
panning the signal.
Naturally, this effect is mainly used
for electric guitars, in particular, to
reproduce classic "vintage" sounds.
But it is also an interesting special
effect for vocal sounds.
Tab. 5.3: Modulation and pitch shifter effects
Effect algorithms nos. 20 through 24 are multi-effects algorithms combining various effect types with a delay
or a reverb algorithm. For example, effect #24 allows you to chorus a lead guitar sound and at the same time
add a room reverb.
