Tremolo
A periodic modulation of the amplitude (level) of the sound is known as tremolo. The
modulation is controlled via an LFO. The Fender Rhodes suitcase piano features a
stereo tremolo and many other electric pianos have a simple, but quite obtrusive,
mono tremolo that can introduce a strange kind of polyrhythmic feel to performances.
Note: The original Wurlitzer piano has a mono tremolo with a fixed modulation rate of
5.5 Hz. For an authentic Wurlitzer sound, choose 0°. For Rhodes sounds, select 180°. The
settings in-between result in nice spacey effects, especially at low LFO rates.
Rate
Speed of the tremolo effect (LFO frequency).
Intensity
Amount of amplitude modulation. With 0 selected, the tremolo effect is switched off.
Stereophase
At a setting of 0°, the level undulates in phase on both channels. With 180° selected,
the modulation is perfectly out of phase, resulting in a stereo tremolo effect that is also
known as “auto panning. The effect is similar to manually turning the pan pot from side
to side.
Chorus Intensity
The well-known chorus effect is based on a delay circuit, the delay time of which is
permanently modulated by an LFO, while the delayed effect signal is mixed with the
original dry signal. It is the most popularly used effect on electric piano sounds. This
parameter regulates the intensity (the amount of delay time deviation), while the LFO
rate is fixed at 0.7 Hz. Pay close attention when using high values as this may result in
the piano sounding detuned.
