Using the EVP88 Tremolo Effect
A periodic modulation of the amplitude (level) of the sound is known as a 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,
which can introduce a strange kind of polyrhythmic feel to performances.
Rate knob: Sets the speed of the tremolo effect (LFO frequency).
Intensity knob: Determines the amount of amplitude modulation. When it is set to 0,
the tremolo effect is turned off.
Stereophase knob: Determines the relative phase shift between the left and right
channels, ranging from 0 changes the level of both channels—in phase. A 180-of-phase
modulation, resulting in a stereo tremolo effect that is also known as auto panning.
This is similar to manually turning the pan pot from side to side.
Tip: The original Wurlitzer piano has a mono tremolo with a fixed modulation rate of
5.5 Hz. For an authentic Wurlitzer sound, select a Stereophase value of 0 degrees. For
Rhodes sounds, set the Stereophase value to 180 degrees. The settings in-between
result in nice, spacey effects—especially at low LFO rates.
Using the EVP88 Chorus Effect
The well-known chorus effect is based on a delay circuit. The delay time is modulated by
an LFO. The delayed-effect signal is mixed with the original signal. It is the most popularly
used effect on electric piano sounds.
