Resonator
A resonator is a special filter whose response is so sharp that it actually imparts a
pitch to any signal going through it. By tuning the resonator to your instrument and
balancing their relative amplitudes you can accentuate different harmonics in a
guitar tone, for instance. This can be very useful to dramatically change the
character of an instrumentÕs sound.
Mono/Stereo Tremolo
The Mono Tremolo modulates the amplitude of its input signal according to three
parameters: speed, which controls how often the sound changes amplitude; depth,
controlling how strong the tremolos will be; and shape, which controls whether the
amplitude transitions will be hard (drastic) or soft (gradual). Mono tremolo can
recreate the sound of older guitar amps.
Stereo Tremolo alternates the loudness of the signal in opposite channels according
to the same three parameters as the Mono Tremolo effect. On slow speeds with a
soft shape, stereo tremolo provides continuous automated panning. At low to
moderate depths and moderate speeds, the vibrating sound of traditional electric
pianos can easily be reproduced.
Stereo Simulator
This effect is useful for ÒwideningÓ a flat sound to produce a wider stereo field. It
takes a mono sound source and creates the illusion that sound is emanating in stereo
from a pair of speakers placed somewhere around the listener. By doing so, the
sound appears spatially distributed, and takes on a lively new ambiance. When
placed at 0 degrees, there is virtually no effect. At 90 degrees, there is an illusion
that the speakers are on either side of the listener. At 99 degrees, the sound
appears to come from slightly behind the listenerÕs head.
